Mark Ginther

When Ginther came out of Jenks (Okla.) HS in 2009, scouts projected him as a future top-three-rounds pick. Four years later, they still like his athleticism and arm strength but wonder if he'll hit enough to make an impact against pro competition. After totaling 22 homers in 2010-11, he hit just five this spring. He has size (6-foot-2, 199 pounds) and strength but undermines his righthanded power potential by being too aggressive at the plate. He has struggled with wood bats in summer competition as well. A quarterback who led Jenks to two state 6-A football titles, he moves well at third base. A 48th-round pick by the Phillies out of high school and a 14th-rounder by the White Sox last year, he'll get drafted for a third time as a senior.
