The Pirates' No. 1 prospect, Tyler Glasnow, threw six scoreless innings Tuesday before he was charged with a run that snapped his shutout streak at 18 innings. Despite giving up the lone run, Glasnow led Class A Advanced Bradenton to a 6-1 victory at Jupiter.
Before Tuesday, Glasnow hadn't allowed a run since July 27, when he gave up three in a loss at Lakeland. Against Jupiter, he gave up one run on four hits and three walks in 6 1/3 innings. He struck out 10 batters, marking the fifth time in 20 starts this season that he has reached double-digit strikeouts.
Glasnow, ranked No. 19 on MLBPipeline.com's Top 100 Prospects list, had thrown six scoreless innings in each of his last two starts and again made it through six innings without giving up a run Tuesday. But he returned to the mound in the seventh and issued a one-out walk to Sharif Othman. That ended his night and the Hammerheads scratched out a run on a single, a fielder's choice and an error off right-hander Tyler Sample.
Jupiter wasn't able to mount any more of a comeback and Glasnow picked up the victory, improving to 10-5 with a 1.52 ERA. He has struck out 132 batters and walked 54 in 106 1/3 innings this season. His ERA is the best in the Florida State League and he ranks second in strikeouts, despite missing most of the first month of the season due to a back injury he suffered in Spring Training.
