Jack Hartman

Hartman began his college career as a position player at Tallahassee (Fla.) JC in 2017. He transferred to JC of Central Florida in 2018 and pitched out of the bullpen while continuing to swing the bat, then became a pitcher full-time when he arrived at Appalachian State in 2019. In his second year of focusing solely on pitching, Hartman had a significant velocity jump out of the Mountaineers bullpen before the season shut down due to the coronavirus pandemic. When he’s on, Hartman has a fastball in the 94-97 mph range and a plus slider that he can both throw for strikes. Inconsistency has been an issue, however, and he'll also have outings where his fastball sizzles but his slider is a well below-average pitch and his control abandons him. Hartman averaged 12.8 strikeouts-per-nine innings at Appalachian State, but also 6.9 walks per nine. Hartman was a reliever exclusively in college and will remain one in pro ball. Because of his limited time focusing on pitching, some teams believe they may figure out how to improve his command. If they can, his pure stuff is good enough to pitch in the seventh or eighth inning. Even with his warts, Hartman's stuff makes him is strong senior sign candidate for teams.
