Plan for 2027

  1. 1
    Bat speed high ask Get bat speed back to his best season

    70.3 mph average (27th percentile); he averaged 71.4 in an earlier season. Only bat speed he has already shown.

    Bat speed: 70.3 mph target 71.4 mph Check at the 2027 All-Star break · noise then ±0.2 mph Bat 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

Does the most damage down over the middle (+1.1 vs. league per 100; 0.5 standard errors on 86 pitches, inside the noise for the best of nine cells).

Weakest down and in (−3.6), but only 1.6 standard errors from average on 59 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,237 pitches · faded cells are within one standard error of average. A spot is called only when it is farther from average than the best or worst of nine average cells gets 95% of the time (set from the league’s own pitches: about 3 standard errors above, 2 below).
