Our engine ran 10,000 Monte Carlo plate appearances of Kyle Schwarber against Clay Holmes at Wrigley Field. It gives a 18.7% probability of a hit per plate appearance, with 25.4% strikeouts, 16.9% walks and 4.2% home runs per PA. Average simulated length: 3.49 pitches per plate appearance. No raw head-to-head rate drives any of these numbers; the inputs are regressed multi-season rates for both players (methodology below).
| Outcome | Sim probability | Rate |
|---|---|---|
| Walk | 16.9% | |
| Strikeout | 25.4% | |
| Hit by pitch | 1.2% | |
| Single | 11.0% | |
| Double | 3.2% | |
| Triple | 0.3% | |

Read rate: 12 career PA is 0.0% of one full batter season. One extra dropped popup changes the career average by 14.3 points.
Re-running the same 10,000 simulated PAs with Wrigley Field's factors (hit 1.02x, home run 1.04x) moves the hit probability from 18.2% in a neutral park to 18.7%, a +0.5-point move.

Inputs: Kyle Schwarber's and Clay Holmes's last-three-season lines (4243 PA / 2944 BF weighted 1x/2x/3x by recency), shrunk toward league average, blended with a log5 odds-ratio matchup model, conditioned on real league count-level pitch and batted-ball frequencies, and park-adjusted with committed park factors. The count process is calibrated per pair so simulated strikeout and walk rates land within 0.3% of the model targets (this page: 0.02% K error,0.01% BB error).
Head-to-head history never enters the simulation; a batter-pitcher pair shares a few dozen career PAs at most, and honesty means the model's priors are the players' own multi-season tendencies, not a 30-PA fluke. Full engine notes on the methodology page.
