August 17th, Rockies vs Dodgers - Simulation

I used my simulator to simulate 100000 baseball games between the Rockies and the Dodgers using what to the best of my knowledge will be close to today's starting lineups.  The simulator outputs a win probability for each team, along with the average total runs scored, a distribution matrix of all the final scores and how often they occurred, and an averaged box score tally of all games combined.  The simulator takes into account such things as defense, park factors, home field advantage, pitchers tiring and a proprietary set of hitter and pitcher projections that are calibrated on a daily basis.  There are many references to Vegas win probabilities.  This is just a measuring stick I use to determine how well my simulator does.  This by no means is meant as a tool to use to gamble on baseball games, it is more of an exercise in analyzing baseball games.  You may find it strange that there are so many one run games listed as the most likely score, and that the home team is always favored to win in the top couple of scores.  This is due to basic math and the way that baseball rules play out of having the home team bat last.  Here is a great article explaining this phenomenon.  Here are the latest Vegas MLB odds.

Notes:  The Dodgers are solid favorites to take the first game of the series against the Rockies.  There is not much at stake other than possibly third place in the NL West.  Nobody expects the Dodgers to throw games or want to lose, but the Dodgers could benefit from a few extra losses down the stretch of the season to make sure their first round draft pick in 2011 is protected.  But let's not go there quite yet.  Jhoulys Chacin the Rockies pitcher has a solid K/9 rate of 9.73 in 82+ innings of work this year.  But on the flip side he has a BB/9 of 4.15, so the Dodgers are likely to see an equal portion of flame throwing and wildness from the young Rockies pitcher.  Kershaw is putting up similar numbers, albeit in a much larger sample size.  Kershaw has a rather large difference between his FIP and xFIP due to a very low HR/FB of 5.5%.  Get your game score and over/under guesses in.

Over/Under Questions:

1. Total runs both teams combined: 6.5
2. C.Kershaw number of pitches: 107.5
3. C.Kershaw strikeouts minus Jhoulys Chacin strikeouts: 1.5
4. Number of walks allowed by all Rockies pitchers: 4.5
5. Dodgers runs scored minus Rockies runs scored: 1.5
