1. OF Eric Hartman | 20 | AA | 2028

A 2024 20th-round pick as a high-school draftee out of Alberta, Canada, Hartman was the talk of the prospect universe early this summer as a 19-year-old laying waste to High-A pitching. Things haven’t gone as well since his promotion to Double-A, where he’s slashing .217/.336/.321 with two home runs and 34 strikeouts (27.2 percent) through 27 games. It’s still good for a newly minted 20-year-old, honestly, but it speaks to some hit-tool concerns that will linger perhaps even if/when Hartman has some success at the major league level. Everything else about the 6’1” 185 pound lefty bat is pretty exciting. He’s stolen 52 bases in 61 attempts and hit 26 home runs in 121 games across two levels.
