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 [1.07, 1.57] · n=378 picks
Top 15 by delta (tonight's probability minus the bat's own baseline). The headline board.
SLEEPERS
0.68x95% CI [0.12, 1.31] · n=139 picks
Top 5 by lift among bats with a LOW baseline — the ones a power list would not surface.
AROUND SLATE
1.24x95% CI [0.96, 1.53] · n=347 picks
One bat per game, the best by delta. Broad coverage rather than concentration.
FAVORITES
0.85x95% CI [0.66, 1.05] · n=288 picks
Top 10 by raw probability. Published for transparency; NO edge is claimed here — expect roughly 1.0x baseline.
MOUND SUPPRESS
0.77x95% CI [0.60, 0.95] · n=98 picks(inverted — below 1.00x is the win)
The three starting pitchers whose opposing lineups project LOWEST. Graded inverted: below 1.0 is the win.
MOUND VULN
1.29x95% CI [0.97, 1.62] · n=44 picks
The single starting pitcher whose opposing lineup projects highest.

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 (1279 picks, deduplicated across sections). Buckets with fewer than 50 picks are greyed — they are too small to read.
