Our engine ran 10,000 Monte Carlo plate appearances of Matt Olson against Tyler Glasnow at Dodger Stadium. It gives a 16.3% probability of a hit per plate appearance, with 34.1% strikeouts, 11.2% walks and 2.9% home runs per PA. Average simulated length: 3.35 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).

Read rate: 17 career PA is 0.0% of one full batter season. One extra dropped popup changes the career average by 7.7 points.
Re-running the same 10,000 simulated PAs with Dodger Stadium's factors (hit 0.97x, home run 0.93x) moves the hit probability from 17.0% in a neutral park to 16.3%, a -0.7-point move.

Inputs: Matt Olson's and Tyler Glasnow's last-three-season lines (4227 PA / 2118 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: 0.05% K error,0.04% 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.
