    Walks a bigger share of batters than 76% of Triple-A pitchers (500+ pitches): the 76th percentile for walks. The player page’s tracking bar ranks the other way (higher is better). The target beats regression to the mean: it is his expected next season with no plan (a value this far from the Triple-A median tends to come back part of the way) plus the step a quarter of similar players beat. At 25, he’s about 2 years younger than the typical Triple-A player, so the level median is a high bar.

    Walk rate: 13.9% target 10.5% no plan ≈ 12.7% No one-season check: a lean. Telling this target from noise takes about 384 batters faced; he had 137 in 2026. Triple-A tracking

Each goal is checked when his sample can tell the target from noise: the 2027 All-Star break if it can by then, else season’s end or the sample it needs; if no single season can, it’s a lean. Coach card
