2010 Simulation Results


The 2010 regular baseball season is over and below are the statistics of how the simulator did for the 2010 season. Method of measurement is Return On Investment (ROI), which is calculated by taking the total amount won betting, divided by the total amount of money bet.

Measurement ROI
Overall 3.42%
April 8.95%
May -1.37%
June 1.20%
July 5.52%
August 1.28%
Sep/Oct 5.66%
National League 4.98%
American League 1.53%
Interleague 5.03%
Favorites -4.00%
Underdogs 8.04%
Visitors -0.75%
Home 6.06%
Home Underdogs 15.55%
Home Favorites 0.19%


To put this in perspective, let's say that you average bet was $10 on each game, (this is a simplified example) - but just to get an idea on what you'd make, it would be around $730 and $7300 on average bet sizes of $100. From the table above, the simulator cleaned up on "home underdogs".

Seasonal Team Projections, Read View Mirror


It's time to take a look at how the simulators pre-season team projections are working out. Keep in mind that the simulator simulated the season 10,000 times, and the actual empirical result is nothing more than one sample, so you are bound to see a few teams miss their projected win totals by quite a bit. Here is how the projections look thus far.

Team Division On Pace Wins Simulator Wins Delta Wins Closest Rank
Padres NL West 93.9 72.3 21.6 30th
Dodgers NL West 90.2 93.8 3.6 10th
Rockies NL West 90.2 86.7 3.5 9th
Giants NL West 86.5 75.6 10.9 19th
DBacks NL West 61.9 82.7 20.8 29th

Blue Jays AL East 80.1 74.7 5.4 14th
Orioles AL East 53.4 71.5 18.1 28th

Notes: The five closest seasonal win total projections so far are the Royals, Yankees, Angels, Twins and Cardinals. The five biggest surprises have been the Padres, Diamondbacks, Orioles, Mariners and Pirates.

All Star Break, NL West Simulated

Using my simulator to play out the remainder of the schedules for the 2008 season for the five NL West teams. Here is how the simulator predicts the final outcome of the division to be (20 seasons were simulated for each team).
  Current Final / Simulated Best Worst
Team Wins Losses Wins Losses Season Season
Dodgers 46 49 80.2 81.8 88-74 75-87
DBacks 47 48 80.1 81.9 89-73 70-92
Giants 40 55 74.7 87.3 82-80 69-93
Rockies 39 57 73.0 89.0 81-81 66-96
Padres 37 58 68.0 94.0 74-88 60-102

Skinny: The simulator is predicting the top four teams to play close to .500 ball the rest of the season, with the one exception of the Padres who are predicted to go 31-36 in their remaining games. Surprisingly, the Giants are expected to have the best record in the NL West the rest of the way winning at a .517 clip. The Rockies posted the 2nd best remaining season record, with a .514 winning percentage. The Dodgers finished narrowly behind the Rockeis with a .510 winning percentage. The DBacks mirrored their pre-All Star break record with a .494 winning percentage the rest of the way out. The simulator is predicting a dead heat between the Dodgers and DBacks for the NL West crown, with the Dodgers averaging a season total of 80.2 wins and the DBacks 80.1 wins. The difference, most likely within the margin of error. The NL West title will most likely come down to a factor like, who makes the best trade before the deadline, or which team stays the healthiest, or which team gives the most playing time to it's best players. The latter of which is something that could easily kill the Dodgers 2008 season.

Note of personal interest: I was quoted in ESPN The Magazine, which has an article ranking the top sports franchises. My comment was a bit sarcastic but nonetheless very serious in regards to nickle and diming that takes place in order to attend an MLB game. (Hat Tip: Molly Knight)

NL Central - Best Bullpens

Note: Updated 1/29/08
Time to rank the NL Central bullpens. The method I will use to rank NL Central bullpens is to give each team the same batting lineup and to start each simulated game in the top of the 7th inning with the score tied and the starting pitcher about to be relieved for each team in their opponents half of the 7th inning. This way the only difference between the two teams will be the bullpens. 5000 games are simulated home and away with each team facing each other. Winning percentages are added and then averaged. All games are played in a neutral park environment and of course 2008 ZIPS projections are being used. See the table below for results.

Note: The simulation may output slightly different results if I start in the 6th inning or 8th inning as opposed to the 7th inning. Bullpen depth charts from Rototimes and Yahoo were used in determining bullpen depth chart listings.

Rank Team Total
1 STL .5345
2 HOU .5122
3 CHC .4987
4 MIL .4932
5 PIT .4848
6 CIN .4767


No time for an indepth breakdown of these results. If you'd like any further information from this sim study please leave a comment of email me.

NL East - Winter Rankings

Note: This simulation includes Johan Santana as a Met.

NL East - Winter Rankings

For a description for how these rankings/numbers were created, please see the NL West rankings a few posts below.

Team NYM ATL PHI WAS FLA Total
NYM NA .5240 .5449 .5632 .5923 .5561
ATL .4760 NA .5247 .5389 .5620 .5299
PHI .4551 .4753 NA .5332 .5517 .5078
WAS .4370 .4611 .4668 NA .5175 .4706
FLA .4288 .4380 .4483 .4825 NA .4494


Skinny: The addition of Johan Santana makes the Mets a rather large favorite to win the NL East. The one factor that could possibly bring the Mets back down a little bit is the health and effectiveness of Pedro Martinez. The Braves have a decent offense and a solid top half of the rotation. The Phillies offense is not potent enough to make up for some questionable pitching and the simulator puts them in third place. The Marlins aren't very good, and the Nationals are a team on the rise, though still a long way off from competing in the NL East.

NL West - Best bullpens

Note: Updated 2/7/08
Time to take a break from our divisional ranking series and take a look at which bullpen in the NL West is the strongest. Once again the simulator comes in handy at this task. The method I will use to rank NL West bullpens is to give each team the same batting lineup and to start each simulated game in the top of the 7th inning with the score tied and the starting pitcher about to be relieved for each team in their opponents half of the 7th inning. This way the only difference between the two teams will be the bullpens. 2000 games are simulated home and away with each team facing each other. Winning percentages are added and then averaged. All games are played in a neutral park environment and of course 2008 ZIPS projections are being used. See the table below for results.

Note: The simulation may output slightly different results if I start in the 6th inning or 8th inning as opposed to the 7th inning. Bullpen depth charts from Rototimes and Yahoo were used in determining bullpen depth chart listings.

Rank Team Total
1 SD .5405
2 SF .5111
3 LAD .4947
4 COL .4797
5 ARI .4739


Skinny: No surprise here with the Padres coming out on top. Surprisingly, the Giants come out a strong 2nd with the Dodgers a solid 3rd. The Rockies and Diamondbacks who have very similar bullpens on paper come out in a statistical tie for 4th/5th place. The Diamondbacks, while one of the strongest teams in the NL West, didn't fair too well.

Bullpen Configurations used:
Type SD SF LAD COL ARI
Closer Hoffman Wilson Saito Corpas Lyon
#1 Setup Bell Hennessey Broxton Fuentes Pena
#2 Setup Meridith Kline Proctor Vizcaino Qualls
Middle Hampton Messenger Beimel Speier Slaten
Middle Cameron Taschner Brazoban Herges Cruz
Long Ledezma Correia Guo Capellan Petit


How can the Diamondbacks possibly rank at the bottom in this study, you ask?

Well, let's start off by taking a look at the top three pitchers in each bullpen in the following table (Yes, I like tables).

Team IP HR Hits SO BB HR/9 (K-BB)/IP WHIP
SD 229 15 216 196 51 .590 .633 1.166
SF 197 17 191 127 85 .777 .213 1.401
LAD 255 28 222 279 85 .988 .761 1.204
ARI 233 22 225 165 70 .850 .408 1.266
COL 213 21 191 173 79 .887 .441 1.268
Note: All stats adjusted to nuetral park.


How about a look at just the top two relievers from each team.

Team IP HR Hits SO BB HR/9 (K-BB)/IP WHIP
SD 138 8 124 130 36 .522 .681 1.159
SF 146 12 139 98 60 .671 .260 1.363
LAD 162 12 131 195 46 .605 .920 1.093
ARI 149 12 125 98 44 .725 .362 1.134
COL 142 15 124 118 45 .951 .514 1.190
Note: All stats adjusted to nuetral park.


Team Analysis:

Padres: The Padres top half of the bullpen is by far the strongest of any NL West team. They are stingy giving up the long ball and any hits at all. Only the Dodgers fair better in the strikeout and walk ratio category.

Giants: Steve Kline is listed at #3 in their bullpen depth chart and he brings down the Giants numbers in the strikeout and walk ratio and WHIP categories. The Giants top two relievers do a good job of supressing the homerun. It's very interesting that the Giants come out in second place in this analysis when on paper they look like they should come in anywhere from 3rd to 5th.

Dodgers: The Dodgers have an excellent 1-2 punch in Saito and Broxton, then a large drop off to Proctor. The Dodgers will suffer greatly if either Saito or Broxton gets hurt. The Dodgers are the only 1-2-3 bullpen to average over a K per inning (9.847). Scott Proctor drags the Dodgers down quite a bit in the HR/9 category. The Dodgers would benefit greatly from having a more effective pitcher pitch in high leverage innings than Proctor.

Rockies: The Rockies are hurt mainly by their tendancy to give up the long ball, otherwise they are a middle of the road bullpen. They could also use another hard throwing strike out pitcher in their bullpen and perhaps a little bit more control wouldn't hurt.

Diamondbacks: The Diamondbacks bullpen takes a huge hit in the loss/trade of closer Jose Valverde (K/9: 10.91, K-BB/IP: .808). The Diamondbacks bullpen on paper looks very similar to the Rockies bullpen. The Diamondbacks lack an effective southpaw in their bullpen that most of the other teams seem to have. They may suffer in some late game situations if this problem is not remedied. Brandon Lyon, the Diamondbacks new closer does not tend to give up too many homeruns, but he also does not strikeout too many batters either.

NL Central - Winter Rankings

Hot Off The Press!



NL Central - Winter Rankings

For a description for how these rankings/numbers were created, please see the NL West post below.

Team CIN MIL CHC HOU STL PIT Total
CIN NA .5141 .5066 .5006 .5109 .5411 .51466
MIL .4859 NA .5033 .5087 .5183 .5499 .51322
CHC .4934 .4967 NA .5023 .5139 .5474 .51074
HOU .4994 .4913 .4977 NA .5122 .5486 .50984
STL .4891 .4817 .4861 .4878 NA .5185 .49264
PIT .4589 .4501 .4525 .4514 .4815 NA .45888


Skinny: Quite a logjam at the top of this division. Three teams, the Reds, Brewers and Cubs all within the margin of error (.005) of the top spot with the Astros right there behind. Then a significant dropoff to the Cardinals and a huge dropoff to the Pirates. The Reds were bouyed by their good showing against the Brewers, they were the only team to outplay the Brewers head to head. For the Reds Harang was an impressive 4-1 against other #1 starters only suffering a close defeat to Gallardo. Bailey was 5-0 at the #4 spot and Volquez was 5-0 at the #5 spot. The Reds get alot of their strength from the tail end of their rotation. Hill and Sheets were the best #2 pitchers, each going 4-1 in H2H matchups. Ted Lilly dominated the #3 spot with a perfect 5-0.

NL West - Winter Rankings

NL West - Winter Rankings (Updated: 1/28/08)

It's been a busy offseason for most of the teams in the competitive NL West. Using my baseball simulator, I am having each NL West team go head to head against every other NL West team. Each team will play 1000 games, both home and away, against every other team, with their #1 starter facing the other teams #1 starter, with the same being done for the #2, #3, #4 and $5 starters. From this I will get an average winning percentage for each matchup. The totals are then added up and averaged, viewable in the table below, sorted from the top to bottom team. Rosters are still not 100% decided and I had to made some assumptions as to which 5th starter to use on some teams. The sim analysis is not taking into account, pitchers that are injury prone and won't likely make every start for their team, so there is some margin of error. During spring training I will run a more thorough sim test. This will do for now. Please leave comments if you feel like it.

Team LAD SD ARI COL SF Total
LAD NA .5049 .5256 .5330 .5718 .5338
SD .4951 NA .5035 .5301 .5485 .5193
ARI .4744 .4965 NA .5084 .5550 .5086
COL .4670 .4699 .4914 NA .5263 .4887
SF .4282 .4515 .4450 .4737 NA .4496

Skinny: There is a nice separation between all five teams now that ZIPS projections are in for all 5 NL West teams. The Dodgers and Padres matched up evenly head to head. The Dodgers gained some separation with their better performances against the Diamondbacks and Giants. I did not use Jason Schmidt in this sim study, but I did use Randy Johnson. The Dodgers would get a nice boost from Jason Schmidt, as Loaiza would get kicked to the pen. The Diamondbacks would suffer somewhat with the loss of Randy Johnson. The Rockies come down to earth in this study and will be challenged to repeat last years exeptional season. The Giants are a mess!

Think of each sim game as:
Team A(Starting Pitcher, Bullpen, Offense)
VS
Team B(Starting Pitcher, Bullpen, Offense)
