It's almost hard to believe in his one year at Cowley County C.C., Rosenthal was only throwing to first as the team's short stop.
After just one season of JUCO ball as a starting shortstop and closer Rosenthal was drafted by St. Louis in the 21st round of the 2009 draft.
The 21-year old Lee's Summit native is in Double-AA Springfield this season after making the rare jump over High-A Palm Beach.
Rosenthal boasts a mid to high 90s heater that touched 101 m.p.h. on the Hammons Field gun on Sunday, but will pull the string with a change up here and there. The differential between the pitches averages at least 10 miles per hour.
Rosenthal needs to develop his secondary pitches to get to the big leagues. And he's mixing them in more and more.
Rosenthal was invited to major league camp this spring where he made the most of his time on the mound and in the clubhouse.
The solid spring earned him this year's Double-AA nod and even a start for the big league birds in their Hammons exhibition.
