What these mean
BTB Value
His pitches' physics graded on what they should produce this season, 5 = 2025 league average, 1 point = 1 SD.
BTB Trust
Percentile among MLB pitchers (SP 50+ IP, RP 20+ IP), starters and relievers in one pool; higher is better. A typical reliever's season is about 200 batters, so about half the gap between two relievers is noise: expect it to move more than a starter's. A season read of how far the player can be trusted: it describes the player, not tonight's line or projection.
