Facing a starter who doesn't miss bats and hitting near the top of the order.
2 home runs in his last 15 games

Against left-handers this year he is well above average in exit velocity, 81st percentile, with the 49th in barrel rate and the 80th in expected slugging on contact. Nick Lodolo is where that plays: among qualified starters his fly balls leave the yard most often, 73rd percentile from a hitter's point of view. He is also in the 33rd percentile for launch angle allowed, the 48th for ground-ball rate, and the 59th for hard contact allowed. Conditions: a park that plays small for home runs, 92°F with 3 mph wind. We make him 16% to go deep, against the 12% he runs in a normal game; the market implies 11%.
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.
The park plays big for his side and a career-long barrel hitter.

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.
Rolling 30 days, by section
ELEVATED
1.33x95% CI [1.06, 1.59] · n=374 picks
Top 15 by delta (tonight's probability minus the bat's own baseline). The headline board.

One bat per game, the best by delta. Broad coverage rather than concentration.
FAVORITES

MOUND SUPPRESS

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.
