After being held back in extended spring training because of a back injury, Tyler Glasnow made his season debut Friday night for Class A Advanced Bradenton. The right-hander threw five scoreless innings, but St. Lucie came back to defeat Bradenton, 13-4.
Glasnow, the Pirates' No. 3 prospect and No. 26 overall, struck out six batters. He allowed two hits and three walks.
Glasnow broke out last season as a 19-year old with Class A West Virginia. He posted a 2.18 ERA and led all Pirates Minor Leagues with 164 strikeouts in 111 1/3 innings.
