Blake Keitzman

Lefthander Keitzman was a 15th-round draft pick by the Mariners last year Keitzman after his velocity jumped from 84-85 to 87-90 mph, even though he was pitching on a sore knee. He chose to return to school and held the 87-90 mph velocity all year. He also throws a slider and a changeup, and he can command all three pitches. Keitzman can vary his delivery between three different arm slots.
