Luis Severino is healthy but won't be working through his problems in the big leagues.

The New York Yankees announced that the struggling right-hander, who's been out since May 13 with a mild right triceps strain, has been activated from the 15-day disabled list Monday. He was immediately sent to Triple-A as part of a flurry of roster moves.

New York's injury woes continue to pile up, however, as it also placed utility infielder Dustin Ackley on the 15-day DL with a dislocated right shoulder suffered in Sunday's game against Tampa Bay.

Severino was being counted on to emerge as a dominant member of the Yankees starting rotation following an excellent start to his career in 2015.

Instead he's struggled, to the tune of a 7.46 ERA and 12.6 hits allowed per nine innings. In his most recent start on May 13, he gave up seven runs and walked four over just 2 2/3 innings against the White Sox, and left that game injured.

The Yankees are undoubtedly hoping Triple-A does the 22-year-old some good. A lack of starting depth means they're relying on both him and Michael Pineda to find their old forms in order to keep pace with the rest of AL East.

Ackley, meanwhile, is the latest to join the Yankees infirmary, with infielder Rob Refsnyder being recalled from Triple-A to take his place.
