Plan for 2027
- 1 Velocity medium ask Add fastball velocity
Ranks in the 16th percentile of Triple-A pitchers (500+ pitches) on fastball velocity. At 24, a 1 mph gain is realistic: 25% of 40 tracked minor-league pitchers 25 and under added 1+ mph the next season (vs. 9% at 26+); bigger jumps are rare. At 24, he’s about 3 years younger than the typical Triple-A player, so the level median is a high bar.
Fastball velocity: 91.1 mph target 92.1 mph 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
