World Series Simulation, Game #3
I used my simulator to simulate 100000 baseball games between the Yankees and Phillies 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 |
| NYA | PHI | A.Pettitte vs C.Hamels | NYA | 52.83% | 46.70% | 52.40% |
Skinny: Simulator Fun Facts... It looks like according to Vegas, the Yankees are going to be favored in every game of this series. Vegas has the Yankees as slight favorites to win Game #3, while my simulator has the Phillies as slight favorites. The spread between Vegas and my simulator is around 6%. AccuScore has come in with numbers similar to Vegas in terms of win probability, but is predicting an over/under of 10.6 runs, while both Vegas and my simulator see the over/under in the low 9s.

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.

frank, since this is your sim
why not list your favorite and not that of vegas
maybe some of the folks here might like it better to see their fave team listed as better odds

Hey Frank
I have been asking you for days but you keep ducking me. Show me your simulator has a predictive accuracy equal to or higher than 60% based on running simulation on prior post seasons and I will ease up on you. But you won’t, you won’t even tell anyone your accuracy rate. Yet you come every game spouting percentages with absolutely no reliable data to give anyone ANY reason to believe your numbers. You keep calling me names, I simply am asking you to back your shit up… show me why anyone should believe your numbers. If you can’t, like I have been saying… you are about as useful or interesting as a coin flip.

Good morning PSA troll. As I’ve told you atleast a half a dozen times on various SB Nation blogs that you are following me around on, my results are proprietary and I actually don’t care what you think about my simulations. If you want to run some tests on prior data you can visit my blog and scrape all the data yourself and then present it to us in a pie chart, balloon chart or candied apple chart, pick your favorite.

What a sweet boy. Glad you’re here.
I love when people take projections/simulations super seriously, good and bad. They’re just exercises in probability. Nothing offensive about them one way or the other. Take with a grain of salt, and have fun.

FInal Lineups
Phillies WP from 53.30% to 52.43%
With the correct lineups. Only switch was Swisher back in for Hairston Jr. The move helps the Yankees chances slightly according to the simulator.

Score #48 hits
High scoring game, 4 runs above the over/under therefore score number 48 hits.
