Phillies vs Dodgers, Game #2 Simulation
I used my simulator to simulate 100000 baseball games between the Phillies and 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. 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.
Today's Results... (Last simulation ran on Thursday at 9:30PM)
| Visitors | Home | Pitching Matchup | Favorite | Vegas Win Prob | Simulator Win Prob | AccuScore |
| PHI | LAN | P.Martinez vs V.Padilla |
LAN | 57.63% | 56.70% | TBD |
Skinny: Simulator Fun Facts... My simulator and Vegas are in very good agreement on the Game #2 win probabilities. The Game #1 loss dropped the Dodgers 'Series Win Probability' down to 38.1%. A win tomorrow will raise it back up to 51.9%, while a loss would drop it to a depressing 19.9%.

Note: Keep in mind I did this simulation before knowing the actual starting lineups, so some of the players I used may not be starting. Many of the "Players Most Likely To" stats depend on having the correct lineup. The lineups I used are listed below. Chances are you won't see a big difference in win probability from having the lineup order slightly off. Picking the correct starters is more important, especially if one of the better players is taking the day off. But you still won't see a big change in win probability if the starter and backup are interchangeable.

What’s the probability that the Dodgers score 9 runs in the first inning so I don’t have to stress, call my dad to talk me down from a ledge, have my girlfriend cower at the end of the couch fearing she may be a victim of domestic violence at any moment, and have my roommate wake up after my explictive laced tirade? .01%?
Xeifrank, can you determine the probablility that 9 runs are scored in the bottom of the 1st?

That joke still kills me
we need a post-season commenter award show (or post.)

No
I thought it would be funny to give UCLA a probability of his head not exploding.

Those scores are ridiculous
Another slug-fest predicted.
I’m really pulling for #45. We need to have our pitching shut-down this team like they have to so many all year and knock the crap out of their weak starter.
Walks have been the Dodger’s pitching staff Achilles’s heel all year long and this needs to end tonight!
FWIW
1025AM, the “smart money” is moving towards the Dodgers side. The ML is now -149/+141 or a 145/245=59.18% win probability. Hope they know something. Maybe someone saw Matt Kemp chowing down on some spinach at brunch.
vr, Xei
Wow, only one in the top 10 where we held them to one run.
Need the update though, win probability 1!
