PITTSBURGH (AP) The Pittsburgh Pirates have placed right-handed pitcher Tyler Glasnow on the 15-day disabled list.
Glasnow pitched into the fourth inning in his start against the Philadelphia Phillies on Saturday before being removed with right shoulder discomfort.
Glasnow was making his second major-league start and allowed two runs and four hits, walked three and hit two batters in three innings. He said after the game that the discomfort increased as his start went on.
''You come up and this happens, it's definitely frustrating, but worse things have happened, so I'm going to stay positive,'' Glasnow said Sunday.
The 6-foot-8 22-year-old is one of the top pitching prospects in baseball.
The Pirates recalled right-handed reliever A.J. Schugel, who had just been optioned to Triple-A Indianapolis on Saturday. He has a 3.94 ERA in 33 appearances with the Pirates this season.
