TAMPA, Fla. -- Yankees reliever Dellin Betances has inflammation in his right shoulder and will start the regular season on the injured list.
New York general manager Brian Cashman said an MRI was done on Betances on Tuesday after the 6-8, 265-pound right-hander continued to lack velocity in his fastball.
Betances, who normally reached the upper 90s, has topped at 92 or 93 mph throughout spring training.
Betances said he will not throw for three to five days, but doesn't think it's a long-term issue.
Left-hander Stephen Tarpley is among those that could take Betances' spot on the roster.
