A career-long barrel hitter and a career hard-contact hitter.
2 home runs in his last 15 games
The full read
Against right-handers this year he is roughly average in exit velocity, 47th percentile, with the 43rd in barrel rate and the 40th in expected slugging on contact. Freddy Peralta is where that plays: among qualified starters he gives up the highest launch angles, 70th percentile from a hitter's point of view. He is also in the 58th percentile for ground-ball rate, the 56th for hard contact allowed, and the 68th for home runs per fly ball. Conditions: a park that plays big for home runs, 73°F with 2 mph wind. We make him 18% to go deep, against the 11% he runs in a normal game.
Percentiles are against this season's qualified population — 30+ batted balls vs that hand for the hitter, 50+ for the pitcher — computed before tonight. Weather is context; it is not a model input.

Against right-handers this year he is well above average in exit velocity, 86th percentile, with the 82nd in barrel rate and the 79th in expected slugging on contact. Jacob Misiorowski is where that plays: among qualified starters his fly balls leave the yard most often, 70th percentile from a hitter's point of view. He is also in the 45th percentile for launch angle allowed, the 33rd for ground-ball rate, and the 19th for hard contact allowed. Conditions: a park that plays big for home runs, 70°F with 4 mph wind. We make him 16% to go deep, against the 11% he runs in a normal game; the market implies 14%.

Colour is league-relative, not slate-relative — the same percentile cuts the matchup table uses, so a green cell means the same thing every night. Everything is coloured from the hitter's point of view.
The record
Written plainly on the boards; defined exactly in how to read our numbers. The intervals below are the full technical version.
Every pick this model has published since 2026-07-09, and how each one graded. The boards are posted before first pitch and graded the next morning against what actually happened. Misses are shown exactly as prominently as hits — that is the point of publishing this.
How to read it.BASE is how often this bat homers in a normal game. PROB is tonight, given the pitcher, the park and the weather. The gap between them is the entire product — a high PROB on a slugger is not a finding, a high PROB on a bat whose BASE is low is. Ratios below compare home runs actually hit against what those same bats' baselines expected: 1.00x means the picks did exactly what ordinary bats would have.

The three starting pitchers whose opposing lineups project LOWEST. Graded inverted: below 1.0 is the win.

The calibration curve
Of the bats we said had a ~14% chance, did about 14% homer? This is the claim nobody else publishes, and it is the one that cannot be cherry-picked. Every graded pick on a batter board is here (1175 picks, deduplicated across sections). Buckets with fewer than 50 picks are greyed — they are too small to read.
