New York Yankees hard-throwing righthander Michael Pineda has been shut down due to weakness in his shoulder.
Pineda, who was acquired from the Seattle Mariners in the offseason, has been on the 15-day disabled list with tendinitis in his shoulder.
He continued to feel weakness in extended spring training and will not throw for a few days until the Yankees decide on his treatment.
New York shipped promising catcher Jesus Montero and righthander Hector Noesi to Seattle for Pineda, who went 9-10 with a 3.74 ERA as a rookie.
The 23-year-old Pineda struggled down the stretch last season, going 0-3 in his last seven starts.
