Polanco forcing challenges by popping off bases; club seeking more conservative approach
Consider this the "real" return of Tyler Glasnow.
Pittsburgh's No. 1 prospect (No. 10 overall) made his second rehab start since spraining his ankle on May 17, giving up one hit and one unearned run while striking out four batters in four innings of work for Class A Short Season West Virginia. That start followed a bit of a rough outing on June 19, when Glasnow surrendered three runs (two earned) in 1 1/3 innings.
