Jack Leathersich

UMass-Lowell's Jack Leathersich has been in the Riverhawks rotation since his freshman year, but he's best suited to pitch out of the bullpen, which is where he had success in the Cape Cod League last summer. An arm-strength lefty, Leathersich struck out 31 batters in 21 innings of relief for Orleans, running his fastball up to 95 mph, while he works at 88-92 as a starter. He shows two fringe-average breaking balls, a slurve and a curveball, but he slows everything down in his delivery on secondary offerings. Scouts have concerns about Leathersich's mechanics, as he throws across his body with recoil and often loses his arm slot. Some talked him up as a potential top-five-rounds selection, but he'll probably be taken in the eighth- to 12th-round range.
