View Draft Report

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.

Top Rankings

Hartman began his college career in 2017 at Tallahassee (Fla.) JC where he was a position player and hit .267 with three home runs. In 2018, he went to JC of Central Florida where he pitched out of the bullpen and continued to swing the bat. In 2019, Hartman began pitching full-time, and scouts got interested recently when Hartman had a fairly significant jump in velocity. He’s now up to 97 mph on his fastball with a slider that flashes easy plus at times, though the breaking ball is inconsistent. In fact, inconsistency has been one of the concerns scouts have noted of Hartman this spring. When he’s on, Hartman has a heater in the 94-97 mph range, with a banger of a breaking ball while throwing solid strikes. When he’s not on, the fastball still comes out well, but his slider looks more like a well below-average pitch and his control is a much bigger concern. Hartman has posted a 4.28 ERA in 33.2 innings of relief with Appalachian State over the last two years, with 12.8 strikeouts per nine and 7.0 walks per nine. He’s a no-doubt reliever at the next level, but because of his limited time focusing on pitching, teams might believe they can figure out how to improve his command at the next level, where his pure stuff could be good enough for a seventh- or eighth-inning role. There’s a lot of refinement that will need to happen before he gets to that level, but he should be a no-doubt senior sign candidate for teams.
