Mitch Keller

Keller, who was not a presence on the showcase circuit last summer, has a ton of helium this spring after making significant developmental strides. He joins Keaton McKinney to give the Hawkeye State two prep arms that could go in the top three rounds. At 6-foot-3, 195 pounds, Keller has a lean, projectable build with long limbs and is a good athlete. His fastball sits 90-92 mph with late life and downhill plane from a high three-quarters slot, touching 95 in shorter stints. His curveball has average potential, flashing better, though he doesn't consistently finish the pitch. His changeup has improved and flashes average potential. Keller has an easy delivery that should give him average control. His arm circle has some length, with a wrist wrap in the back, but he throws strikes. Keller is the younger brother of Orioles farmhand Jon Keller, a righthander who was also drafted out of Xavier High before signing out of Tampa last year. Mitch is committed to North Carolina.
