Dodgers "Just Another Ho Hum Game" Simulation, September 29th
I used my simulator to simulate 50000 baseball games between the Dodgers and Padres 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. For your viewing pleasure I have also listed a few other games of local interest.
Today's Results... (Last simulation ran at 10:00PM)
| Visitors | Home | Pitching Matchup | Favorite | Vegas Win Prob | Simulator Win Prob | AccuScore |
| LAN | SD | C.Billingsley vs C.Ramos | LAN | 59.68% | 60.43% | 49% |
| MIL | COL | C.Narveson vs J.Marquis | COL | 62.55% | 58.92% | 56% |
| HOU | PHI | W.Lopez vs J.Happ | PHI | 73.33% | 65.20% | 71% |
| FLA | ATL | J.Johnson vs T.Hudson | ATL | 54.13% | 47.13% | 45% |
| MIN | DET | N.Blackburn vs R.Porcello | DET | 54.75% | 56.74% | 51% |
| MIN | DET | B.Duensing vs J.Verlander | DET | 60.94%% | 61.86% | 61% |
Skinny: Simulator Fun Facts... The Dodgers just wanted to celebrate the division title in front of their home fans in San Diego, right? Well, Vegas and my simulator are in pretty good agreement as to the odds of that happening. Someone, please wake up the AccuScore operators, as they actually have the Padres as favorites to win tonight. I mean, yeah... anything could happen, but C.Ramos favored over C.Billingsley??? I often look at the games where my simulator is a huge outlier to look for ways to improve my projections, but this blunder by AccuScore is rather embarrassing. I was worried about my simulator picking the Marlins over the Braves, but then noticed that AccuScore had the Marlins as even bigger favorites to beat the Braves than me. So, I am not sure what to think about these guys. Anyways, back to the Dodgers game. The Dodgers were favored heavier in each of the games against the Pirates and only the game vs the Nationals in which Padilla started were the Dodgers ever a sub 60% favorite to win on this road trip.

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.

I wonder if AccuScore weights more than you do on recent performances by the pitcher. Billingsley, for example.
Yeah, I wonder. They would also be weighting a lot more than Vegas and the general public does too. Who really knows though, as AccuScore is a big black box and there appears to be some important details that they don’t even take into consideration. Atleast that was the case last season when I queried them on their message board before they went dark and started charging for their reports.

that would be my guess
what is the D’s record in Bill’s last ten starts?

3-7
But since wins/losses don’t reflect skill very well and since it’s a game simulator we are talking about, AccuScore would be looking at his peripherals not his won/loss record. In this case, his peripherals over the last 10 games are probably not great but they aren’t terrible.
For example, over the past 30 days he has an ERA of 5.70. On the surface that looks pretty bad. When you calculate his FIP over that same time period it is 3.62, with 24Ks, 10BBs and 4HRs in 23.6IPs. The 15ERs are a product of a lot of bad luck. Fangraphs won’t let me filter by last 60 days, otherwise I would’ve posted those numbers.

Surprise, Surprise, Surprise
I have to give credit where credit is due. AccuScore had a rather nice day.

I'm sure accuscore new Bills would have an awesome game
and that our hitter would hit like the Pittsburgh Pirates.
