Yankees add arms after putting Severino on 15-day DL

In the wake of Luis Severino’s arm injury, the New York Yankees made a flurry of roster moves to reinforce their pitching staff.

Right-handers Chad Green and Conor Mullee were called up from Triple-A Scranton/Wilkes-Barre and added to the bullpen.

Rookie catcher Gary Sanchez was optioned back to Triple-A, and Severino was placed on the 15-day disabled list, interrupting his dreadful sophomore season.

Impressive as a rookie last year, the 22-year-old Severino is 0-6 with a 7.46 ERA in seven starts. He left Friday’s 7-1 loss to the Chicago White Sox in the third inning and was diagnosed with a strained right triceps.

In a separate move, the Yankees acquired right-hander J.R. Graham from Minnesota for a player to be named or cash. Graham, 26, was optioned to Double-A Trenton.

General manager Brian Cashman said Severino has a minor injury and it was not the cause of his problems on the mound this season.

Cashman said Severino will make at least one rehabilitation start in the minors once he’s on the mend. First, the right-hander will not pick up a baseball for five to seven days.

Neither manager Joe Girardi nor Cashman, however, would say whether Severino definitely will have a spot in the major league rotation once he’s healthy.

RAYS — Second baseman Logan Forsythe was placed on the 15-day disabled list after tests revealed a hairline fracture of his left shoulder blade.

The move is retroactive to Tuesday, when Forsythe was hit on the shoulder by a pitch from Seattle’s Felix Hernandez.

Forsythe has not played since then, but the Rays considered the shoulder only sore until Saturday’s MRI examination revealed the slight fracture.

Forsythe, 29, is hitting .308 and leads Rays regulars in hits (33), walks (14) and slugging percentage (.523).
