    He strikes out more often than 66% of Triple-A hitters (150+ PA): the 66th percentile for strikeouts. 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 24, he’s about 3 years younger than the typical Triple-A player, so the level median is a high bar.

    Strikeout rate: 25% target 21% no plan ≈ 24% No one-season check: a lean. Telling this target from noise takes about 464 plate appearances; he had 202 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
