ARLINGTON, Texas — The Yankees bullpen will get a new arm on Monday night, as Miguel Castro was reinstated from the 60-day IL.

The right-hander has been out since July with a strained shoulder and while he has been inconsistent since coming over from the Mets in a spring training deal for lefty Joely Rodriguez, Castro will be welcomed back to a bullpen that has been ravaged by injuries.

Zack Britton became the latest reliever to head to the IL, with his comeback from last year’s UCL surgery cut short by arm fatigue. 

Chad Green and Michael King are out for the year with elbow injuries, Clay Holmes is sidelined until at least the beginning of the ALDS with rotator cuff inflammation and Wandy Peralta is on the IL with back tightness, although he’s expected to be back for the playoffs.

Additionally, Ron Marinaccio left Sunday’s loss to the Orioles in The Bronx with right shin soreness and Aroldis Chapman — while healthy — has been terrible and is far from a lock to make the postseason roster. 

Albert Abreu is also on the IL with right elbow inflammation.

It all adds up to a Yankees bullpen with no clear closer and a significant lack of depth as they head into the playoffs.
