Glasnow was named the Pirates' fifth starter on Friday, Stephen Nesbitt of the Pittsburgh Post-Gazette reports.
Glasnow beat out Trevor Williams and Drew Hutchison for the job. One of Pittsburgh's top prospects, Glasnow posted a 4.24 ERA and 1.50 WHIP in 23.1 MLB innings last year after dominating Triple-A with 133 strikeouts and a 1.87 ERA over 110.2 innings for Indianapolis. The Pirates will gamble on his stuff and hope he can resolve his control issues -- Glasnow walked five batters per nine innings or more at both Triple-A and the majors last season, and his fantasy value is limited if he can't figure out how to limit the free passes.
