Streakin 7/31

,
Cricket matches can take a long time and I'm not spending the time to research how many ends or whatever today's match is supposed to go to, so just the soccer match for me early. I probably won't be around to post anything over the weekend. This is hopefully my last weekend of running around for a while.

230p SV Reid (win or draw) vs. FC Magna Wiener Neustadt
Current Streak: 2

Spread-to-Moneyline Converter

,
This is the best link I can find. Does anyone have anything better?

I know about the SBR converter, but it is seriously flawed. I'd rather intelligently extrapolate on my own after 13 than use it.

The Nugget Vs. Sportsbook.com

,
Here's the comparison of the two GOY datasets I have. Games highlighted in yellow are different by three or more points. There doesn't appear any correlation for the teams in yellow. I'll be analyzing these further as I work to get the first team projections up next week.

Streakin 7/30

,
Slightly better early card today.

745a S. Verplank (win only) vs. S. Appleby
1235p Baltimore vs. Kansas City
815p Los Angeles vs. St. Louis
Current Streak: 2

How much is half of a stroke worth in golf? Verplank is -160/+144 at Pinny, which I assume is large enough to overcome the tie, but I have no idea if my assumption is true. O's later today.

Golden Nugget GOYs

,
I'll be comparing these to Sportsbook in the near future (assuming there are differences), but this ought to give a good idea where teams stand heading into the season in the Golden Nugget's eyes.

These will also give me a good estimate for determining the assumed lines for the team-by-team analyses I plan on putting together.




My initial leans are highlighted in orange. It's kind of hard to figure out exactly how to get a lean late in the season. For example, I think Texas Tech should be garbage this year, so if they are only getting 9 against Oklahoma late in the year, they would be a lean. But currently, Texas Tech is still remembered as being tit's hair from the Big XII championship game, so 9 doesn't seem so ridiculous. That line probably closes north of two touchdowns. Especially late in the season, take them with a grain of salt.

Streakin 7/29

,
The early card blows, but I'm at zero so I suppose I have to play the garbage.

1225p Manchester United (win only) vs. Boca Juniors
345p Zach Duke more innings than Matt Cain
8p Chicago vs. Los Angeles
Current Streak: 1

Duke actually has a slightly higher expected value than Cain (139.1 IP for Duke vs. 131.0 for Cain both in 20 games). No doubt Cain will throw a complete game later when I pick Duke.

2009 CFB Average Odds From Vegas

,


The average odds from Las Vegas show Florida with a 36.3% chance of winning the national championship this year. That seems pretty high to me, but given what they lost from last year, I suppose it could be reasonable.

I'm surprised that OU is the consensus number two team out there. Even with Bradford et al. coming back for another year of school, they have a much harder non-conference road than Texas. While Texas gets UTEP, UCF, UL-Monroe, and at Wyoming, the Sooners play BYU at the House That Jerry Built and Miami at Joe Robbie. For two teams that are otherwise similar (though I would put Texas slightly above OU anyway), it's hard to imagine that OU should be higher than the Horns.

The ACC Coastal Division race should be a dogfight according to Vegas, with Virginia Tech slightly ahead of UNC, Tech and Miami. Obviously, you know who I think is going to come out on top. Throw in Free Shoes and Clemson and the ACC has six teams in the Top 21. In taking GT, I am playing the same game The Saw does with golf plays. VT, Miami*, FSU, and to a lesser extent Clemson all have name value, whereas GT and UNC are up and comers in the ACC. The market is likely overvaluing the first four and undervaluing the latter two.

The only other team worth mentioning is Ole Miss. They are ranked tenth in average odds rankings. I strongly believe they are going to be overrated at the beginning of the season. Judging by their position on the sheets I brought home with me, this is not an opinion of Vegas, but a market reaction. Ole Miss was often 15th to 20th down the list, meaning their lines have move up relative to the rest of the teams. I guess it's only a matter of time before I lose money fading them.

At the moment, I am leaning towards shutting down baseball betting. I clearly derive no pleasure from it and it's not like I am turning a profit, either. In the meantime until football, I plan on approaching team by team analyses based on schedules and anticipated spreads, similar to what Moneyline did last year. I've got some Excel programming to do for Bernoulli trials in order to get expected win distriubtions**, but I'm hoping to compare the lines I come up with to the information Jonny posted last week. I'm not expecting my analysis to be terribly accurate, in fact I'm hoping to get some constructive criticism as I post the lines, but hopefully, it will stimulate some good CFB discussion before the season gets started.

*I realize Miami is up and coming at the moment, but they still have name value to the average square.

** Since I need the entire population of W-L probabilities, I need to find the probability of a team losing to the 1st, 2nd, 3rd, 4th, 5th, 6th (and the 1st, 2nd, 3rd, 4th, 5th, and 7th, etc.) teams on their schedule exactly, then summing over all to get the probability of six losses. 12-choose-6 is 924 and 12-choose-5 (or 7) is 792, so I have a lot of copying and pasting in Excel ahead of me.

Vegas CFB Futures Odds

,
I uploaded the all of the CFB futures data I collected to Google Docs. The families can be found here. I stopped by Wynn and Planet Hollywood, but didn't get printouts of their odds so their data is missing. There was nothing spectacular at either shop. The juice is awful across town except at the Plaza, where the sum of the expected probabilities is 152%.

The CFB Futures Positions

,
I'm glad I did quite a bit of price shopping while I was in Vegas, because I think I got decent value with these picks. We'll see. I'm not entirely settled on my unit size for football, so these are in current units, but I don't think it makes a huge difference for record keeping purposes.

Georgia Tech 75-1 4x to win 300x at the Plaza Hotel and Casino
Michigan State 125-1 2x to win 250x at Four Queens Casino

The rationale for these picks are somewhat square, but in college football, where there are no good metrics, there will be some squareness to any future pick. In my opinion, in college football, schedule analysis plays some role in determining how teams will do, and that was a driver in both these picks.

Georgia Tech is returning 17 starters from a middle of the pack ACC team last year, though everyone except Duke was middle of the pack last year. Their schedule is set up somewhat favorable, getting North Carolina, Virginia Tech, and Georgia at home. Their hardest road game will be in Tallahassee on October 10th.

While those are decent reasons for liking Tech, I have to admit that my opinion of them is driven strongly by the Flexbone offense they run. I'm a bit of a Smart Football fanboy and think GT will thrive in Year 2 of Paul Johnson's offense. With teams only seeing the flex once a year, it gives a strategic advantage to the offense (see: 2008 Georgia game).

The big question mark for Tech will be do they have the talent to compete for the MNC? North Carolina continues to amass talent and Virginia Tech always has a strong defense. Even if they get through the ACC unscathed, they would be heavy dogs to Florida, Texas, or USC in the national title game. Still, 75-1 is the best price I've seen on the Jackets since futures opened and that represents value in my mind.

Michigan State loses Brian Hoyer and Javon Ringer, but neither are big time losses. Hoyer was a typical mediocre Big Ten quarterback, while Ringer got a lot of touches but wasn't particularly explosive when he had the rock.

This pick is basically like Jonny's Penn State future on steroids. Ohio State is universally regarded as the Big Dog in the Big Ten, but have a lot of holes to fill on both sides of the ball and Terelle Pryor was not particuarly impressive throwing the ball in his freshman year (not because he was a freshman, either; the guy had the worst throwing motion I've seen from a D-1 QB). Penn State is regarded as their closest competitor, but again, faces big holes at WR, OL, and DB. Sparty has been picked mostly third in the conference this year and Dantonio has been bringing in good recruiting classes somewhat quietly, but like Tech, faces a talent disparity with the UFs and UTs of the world.

Michigan State's schedule sets up somewhat favorably. I'm not on the Notre Dame bandwagon yet, but the two Directional Michigans will be difficult non-conference tests. Once getting to the Big Ten schedule, they miss Ohio State and get Penn State and Iowa at home, so they couldn't have asked for a better set up heading into the season.

Obviously, all of what I have written is stuff that the books have likely considered in setting these lines, but the fact that I saw GT as low at 40-1 at many books and Sparty as low as 45-1 at one leads me to me think that these plays have value going into the season (or, at least, someone who matters banged these teams down).

I've got some cleaning up to do after getting back from Vegas, but I hope to put up a basic analysis of the futures I found in Vegas which maybe will illuminate some value at offshore books looking forward (or not, but it will be fun to play with numbers anyway).

Going Dark Again

,
This has been one of the worst days for me in recent memory. I was supposed to be getting married in Vegas this weekend, but TheFiancee's mom is ill to the point that doctors aren't allowing her to fly (she'll be ok eventually, just not this weekend).

Instead, now it's just me and a good friend heading out to Sin City tomorrow for the weekend, sans TheFiancee. Those of you with your own TheGirlfriend, TheFiancee, or TheWife can imagine how trying today was.

I'll be back on Tuesday with college football futures bets placed at various casinos throughout Vegas.

Sigh. Down to 12x left in the bankroll again. Whatever. Baseball this year is a sunk cost. I'll be reloading for football season, where I expect (hope?) that last year's aberration will not be repeated.

Record Update - 12 July 2009

,
This is a few days late, but it didn't really matter because of the All-Star Break. A late week surge pushed me back into the green for the week, which was a nice way to start a four day break.



I'm experimenting with this new color scheme, since orange plays a larger role in the site's new theme. Orange indicates teams that did well last week, blue not so much. I wish a pox on Arizona, Oakland, and Washington's front offices.

Where the Value Lies - Week 15

Future Win Totals Thinking, Take 3

,
On Walter's suggestion, I played with the binomial distribution. It's not perfect, but it's better. I now get an expectation of 1.53 teams going undefeated and 2008 USC with a 33.85% chance of having exactly one loss and 19.02% chance of going undefeated, both of which make a lot more empirical sense.

This isn't perfect, because I tried to reverse engineer the E(wins) out of the binomial distribution, until I realized I couldn't get half wins back out, so the E(wins) calculation is using the same assumptions as before (e.g. symmetry).

In any case, I'm not really planning on using this for anything other than making fun of retard fanboys who think Georgia is going to win the national title (these numbers give 2008 UGa a 17.1% chance of exactly one loss and a 5.1% chance of going undefeated -- prescient), so it doesn't need to be perfect, but I think Jonny will be able to write some good posts with these.

SftC 7/14

,
Just one early.

10a Zec Pesciric vs. Llagostera Vives
7p Connecticut vs. Los Angeles
Current Streak: 3

None of the other early options are much better than a coin flip.

Future Win Totals Thinking Revisited

,
I've got time to put the full record update up since games don't start again until Thursday, so I figured I would add to this post from last week.

Since I figured out the expected wins of each team from the totals posted at BetUS, all I needed was a standard deviation to come up with a distribution of the probability of each team having a particular number of wins. I did this by using last year's totals and actual results to come up with a root mean squared error estimate of the standard deviation, which was around 2.16.

I'll let Jonny analyze each particular team, but I came up with an unexpected and almost assuredly erroneous result. The numbers show the expected number of teams that should go undefeated is 4.27.

There a couple of reasons that immediately spring to mind why this number is wrong. First off, my methodology could be wrong. I used a normal distribution to estimate probabilties for discrete data. While not terrible, it's still not good (for math geeks, this is analogous to using the trapezoidal rule for estimating integrals).

Also, it may not be a good idea to use a symmetric, normal distribution for totals that are 10, 11, or 12, since the tails of a normal distribution go to infinity and you are buttressing against the total possible number of wins.

Another reason would be that last year's RMSE is not representative of the true standard deviation of the distribution. The last thing that comes to mind is the books shading the lines high for the expected good teams, expecting to take a lot of over action.

To use a further example, last year Moneyline, when he was still running a blog, estimated USC's chances of going undefeated at 14.8% and their chances of one loss at 32.4%. Using this methodology, 2008 USC had a 31.3% chance of going undefeated and a 17.7% chance of one loss. Obviously, Moneyline's numbers are way closer to reality than these are.

There is quite a bit of room for improvement here, I'm just not sure where.

Derby Night 7/13

Future Win Totals Thinking

,
Earlier today, Jonny approached me with a question regarding win totals for the upcoming college football season. BetUS has regular season win totals up for most of the major conference teams for 2009. I was asked to compute win expectancies based off the juice. It seems straightforward at first, but I made some assumptions along the way and I want to make sure they are right.

Here is the methodology: first, find the actual juice adjusted probabilties from each line by adjusting each outcome's odds to probabilties then dividing through each outcome's probability by the sum of the probabilities of the two outcomes.

Then, if the total is a whole number, multiply the over juice adjusted probability by the total plus one and the under juice adjusted probability by the total minus one. If the total is a half number, the procedure is the same, except instead of adding/subtracting by one, I added or subtracted by one-half. Two examples follow.

--------------------------------

Example 1.
Team A o10.5 -130/u10.5 +110

p(-130) = 1.3/2.3 = 56.52%
p(+110) = 1 - (1.1/2.1) = 45.73%

.5652 + .4573 = 1.0414

56.52%/1.0414 = 54.27%
45.73%/1.0414 = 45.73%

E(A) = 11*.5427 + 10*.4573 = 10.54 wins



Example 2.
Team B o10 -130/ u10 +110

E(B) 11*.5427 + 9*.4573 = 10.08 wins

---------------------------------

So, the assumptions I want to check are: the juice adjustment to the probabilities and the calculation of the win expectancies by adding one or one-half.

Obviously, one assumption is that the probability distribution is symmetric, which may not be valid for Florida (o/u 11), for example.

I decided on adding one or one-half because of my SftC experience with soccer odds. When calculating the probabilities for three outcomes (Team A, Team B, or Draw), they are proportional to the Team A pk/Team B pk odds. In other words, If Team A is 35% to win, Team B is 35% to win, and there is a 30% chance of a draw, the odds end up at Team A pk 50% and Team B pk 50%. So, by adding one or one-half, I am calculating the odds of the outcomes that can actually happen, since there is no push option.

The reason why I am questioning myself, beyond never really thinking about it before today, is because the cutoff point for moving a line is different if the total is an integer or a half-number. For a whole number, over -200/under +150 equals a quarter of an expected win. Any higher, and you would expect the book to move it.

---------------------------------

Example 3.
Team C o9 -200/u9 +150

p(-200) = 2/3 = 66.67%
p(+150) = 1- 1.5/2.5 = 40%

66.67%/1.0667 = 62.5%
40%/1.0667 = 37.5%

E(C) = 10*.625 + 8*.375 = 9.25

---------------------------------

If you do the same calculation for a half number line, you don't get to the value to move the line.

---------------------------------

Example 4
Team D o9.5 -200/u9.5 +150

E(D) = 10*.625 + 9*.375 = 9.625

---------------------------------

Obviously, the mathematical reason for this is the larger spread on the endpoints (8 and 10 vs. 9 and 10). But is this right? Should the books be more willing to move the total off an integer than a half-number?

I'm finding myself questioning this outcome, because I think win expectancy should be normally distributed, and therefore the same amount odds should persuade the book to move a number, whether the total is a whole number or a half number.

On the other hand, there is also the push factor that has to be thought about. By moving the line off a half-number, the book creates an opportunity for a push, which I assume would be an undesireable outcome. Does the math prove that or did I make a mistake somewhere? I assume the latter.

In any case, assuming the math is right, Jonny should have win expectancies posted on his blog sometime soon.

This was I wanted to see when I got home from work today.

Looks pretty normal to me.

Honduras +1.5 is the best look, but even it is less than 60%.

Well, what do you know. A big WNBA favorite won.

Plays
310p Washington +159 2x

I was surprised that with so many early games, this is the only one I liked.

Leans

710p OAK (Cahill) +160 @ BOS (Wakefield)
810p CLE (Laffey) +127 @ CHW (Contreras)

I think Oakland is the only sure look here.

Current Streak: 5

I can't find good lines for any of the afternoon options. Cavendish is obviously the favorite at the Tour, but I can't tell if he >50%, let alone higher than that for my streak. DSB says he found -225 at BetUS.

The Cubs/Braves total isn't listed at the moment, so trying to figure the correct side on the baseball prop is failing.

And Argentinian soccer odds are kind of hard to come by. I think because Rosario Central is pk and +0.5 -131 at Pinnacle, that means RC w/d is right, but unless someone confirms that, I'll pass.

Tuesday 7/7

Me, this morning:

Is the market really reacting that wildly to the 22-1 beatdown last night?

JA Happ, 2009: 5-0, 2.96 ERA

Or it could be that. One or the other. Thanks to the returning Jonny for relaying that information to me. As always when it comes to anything baseball related, I'm an idiot.

Plays
705p Cincinnati +129 2x
810p Cleveland +147 3x

The books don't want any part of Bruce Chen against Verlander. Surprising.

Leans
805p ATL (Vazquez) -104 vs. CHC (Dempster)
810p CLE (Sowers) +150 @ CHW (Buehrle)

245p St. Patrick's/Cork u2.5 goals

Not sure how shaded that line is (LANCE!!!111!1!!), but if it's fair, it's a solid early pick. The under is definitely the play in the soccer match later.

Monday 7/6

You win, Wagerline.

Plays
705p Kansas City +127 3x
805p PIT/HOU o9 +100 2x
840p Washington +188 2x
940p SD/ARZ o10 -116 3x

That SD/ARZ total is assuming Matchbook opens a 10.5 market. I'd rather not lay -117 at o10. I need to get better at assessing baseball line movement, because that was at o10 ev this morning.

UPDATE: I changed my mind on the 10 vs. 10.5. I figured it would end up at -102 once MB opened the 10.5 market. o10 -116 is slightly better mathematically.

Streak for the Cash
705p Philadelphia vs. Cincinnati

Where the Value Lies - Week 14

,
The Royals and Tigers are new additions to this week's lists. The Nats, Dbacks, and Tribe are all going to be good options for the forseeable future. I feel like going forward, fading the Tigers and Rangers should be advisable, as well, just based on what I read on the internet.

These numbers are for games through Saturday. July 4th.

Overrated
1. Tigers +5.2
2. Giants +5.1
3. Astros +4.7
4. Brewers +4.0
5. Rangers +3.7

Underrated
1. Nationals -10.4
2. Rays -7.8
3. Indians -6.3
4. Diamondbacks -5.8
5. Royals -3.2

I'm adding a new feature this week, that will be expanded going forward. For now, I am going to add the teams that had the largest delta-D3 over the last week. As I save more data, I'll add bi-weekly and monthly deltas as well.

Best Delta-D3 LW
1. Astros +1.8
2. Marlins +1.6
3. Yankees +1.5

Worst Delta-D3 LW
1. Giants -1.5
2. Blue Jays -1.4
3. Red Sox -1.0

I'm not sure these weekly numbers are going to have much value, because the top teams and bottom teams will have likely played each other and because people's opinions won't change a whole lot over the course of a week. Going forward, I expect the bi-weekly and monthly numbers to have a lot more value from a gambling perspective.

My guesses were way off of what Wagerline is showing this morning. The only sure play is Kansas City tonight. Otherwise, I'll need to re-examine things when I get home. Oakland and Washington have large Wagerline splits, but I'm struggling to see how those lines are shaded, even though they are two of my favorite teams to play.

Streak for the Cash
1p Kalmar FF (win or draw) vs. Malmo FF
Current Streak: 1

I guess the sports books enjoy paying out 2.5-to-1 a helluva lot more than 28.5% of the time on WNBA games. What is that, like the third time we've lost on a favorite better than -250?

Why have four different people hit my blog in the last 24 hours from googling "Stallone's namesake?" I mean, on what planet does someone need to search for that?

Record Update - 5 July 2009

This week didn't feature any particularly rough days, but there wasn't a good day to be had either, except Saturday.



No teams even really stood out as being particularly bad or good. It was a boring, losing week.

Two. Months.

Yes, I'm obviously getting too excited about the return of football.

Current Streak: 6

Tiger to win is -165/+145 at 5Dimes. I think that is fair, but hopefully The Saw or ML will confirm. If it is, I'm passing until the Sparks (that's Los Angeles' WNBA team - I looked it up, too) late.

Looks like another stressful weekend upcoming.

1005p Baltimore +138 2x

Streak for the Cash
8p San Antonio vs. Chicago
Current Streak: 6

I played the Cubs this afternoon, so the streak is pending.

Real Salt Lake is -160 to win. That would be right on the borderline for a play at 10p at W6, if the WNBA game is over. Obviously, when the Cubs or Silver Stars lose, it's a must play.

What Else Is There To Do There?

Well, at least SftC went well this afternoon.

I guess I missed it when he started a game earlier this year for the Royals, but I had no idea Bruce Chen was still in baseball.

Plays
1235p ARZ/CIN o8.5 -102 2x
Pass: Pirates

This seems marginal. It's based solely off consensus numbers. I think the Maholm play might be better, but it's too early in the morning to trust instincts.

Leans
710p ATL (Vazquez) -138 vs. PHL (Happ)
1005p BAL (Guthrie) +149 @ LAA (Lackey)

Streak for the Cash
8a Dementieva/Williams o18.5 games
1120a Venus Williams wins by 2-0
245p FC Zestaponi (win or draw)
Current Streak: 3

Venus is a surprising -160 to win 2-0 in the second tennis match. FC Zestaponi w/d is about 61% later in the afternoon, too, so it seems like a straightforward plan today.

Seattle and Colorado have flashy Wagerline numbers, but neither of them particularly excite me this morning.

Streak for the Cash
10a Hewitt/Roddick 3 or 5 sets
Current Streak: 1

I've got the set prop around 62% to win. Start w/d in the afternoon.

Did the Streakmaster screw up yesterday? The Norwegian soccer game was definitely available when I posted, but obviously was taken down by the afternoon, replaced by an internation friendly the WSOP HORSE winner. Not that it matters.
