DETROIT -- The Yankees placed right-hander Alfredo Aceves on the 15-day disabled list on Wednesday with lower back discomfort, recalling outfielder Greg Golson from Triple-A Scranton/Wilkes-Barre.
Golson, 24, appeared in the May 4 game against the Orioles as a defensive replacement but did not bat. Yankees manager Joe Girardi said that the Golson move was made with Wednesday's day-night doubleheader in mind.
"We've been short outfielders, and we felt we were covered pitching-wise," Girardi said. "With this doubleheader, we want to make sure all of our bases are covered position-wise."
Kevin Russo remained on the roster for that reason, because he is capable of playing several positions as well as the outfield. The Yankees also have a mystery pitcher -- likely right-hander Jonathan Albaladejo -- waiting in the Detroit area just in case their bullpen gets taxed in the first game of the twinbill.
Aceves had said that he was looking forward to having further tests on his lower back, which he felt grab at him while pitching a bullpen session on Tuesday. He has been hampered by repeated soreness and Girardi said there is no timetable for his return.
"Backs are tricky," Girardi said. "You never know. It could be a week, it could be a couple of days, it could be two weeks. You just don't know."
