Every number here is a probability, not a call. Over the last 14 days the next-pitch model was graded on 34,173 real pitches: the top pick was right 39% of the time, and stated probabilities landed within 1.4 points of how often things actually happened. It grades itself every night and corrects what it can.

Each figure is the median of the simulated games with an 80% range beside it. Pitch counts are estimated from batters faced (fitted on 17,200 real outings; typical error 8 pitches). These assume the starter is not pulled early for a reason the model cannot see — an injury, a blowout, or a quick hook.
Park and weather
1.09×park
1.09×run environment
the park favours hitters (1.09x runs). Park factors are measured from 25,110 games by comparing each club at home with the same club on the road, so a good offence does not inflate its own park. Player rates are park-neutralised before this is applied, or the park would count twice.
What this does not know
- starters are pulled around their own typical workload and a bullpen composite finishes, but individual relievers are not modelled, so a specific closer in a specific inning is not
- defence beyond what is already in the pitcher's line is not modelled, and neither are pinch hitters or intentional walks as a choice
- lineup not posted; using the order most recently used
- 2 of 18 hitters have under 50 plate appearances on record
- bullpen ordered by measured availability: Brayan Bello (long, 4d rest, 45% likely); Jovani Morán (middle, 3d rest, 46% likely); Tommy Kahnle (middle, first appearance in a while, 45% likely); Alec Gamboa (middle, 2d rest, 40% likely)
- run environment: the park favours hitters (1.09x runs)
- no weather posted yet; temperature and wind are not in this projection
