Making his MLB debut, Glasnow (0-1) pitched 5.1 innings, allowing four runs on three hits and two walks while striking out five against the Cardinals.
The No. 8 prospect in baseball, according to MLBPipeline.com, was impressive in his long-awaited debut. He threw 55 of his 87 pitches for strikes while inducing nine swings and misses. Glasnow held the Cardinals off the board for three frames before giving up one in the fourth, a solo shot in the fifth and running into more serious trouble in the sixth. The 22-year-old right-hander has an uncanny ability to rack up strikeouts, but has struggled to have consistent control over his pitched in the minors, thus leading the Pirates to hold off on calling him up until now.
