11:34 am: O’Day will be shut down from throwing for a few weeks, manager Aaron Boone told reporters (including Kristie Ackert of the New York Daily News).
9:15 am: The Yankees are placing righty reliever Darren O’Day on the 10-day injured list, retroactive to April 30, with a right rotator cuff strain, the team announced. Fellow righty Michael King has been recalled from the alternate training site in a corresponding move.
New York signed O’Day to bolster their already-strong bullpen over the winter. The submariner enjoyed a pair of highly-productive seasons with the Braves from 2019-20 and has continued to pitch well (albeit not quite at his Atlanta level) in New York. O’Day has made ten appearances and worked nine innings, allowing three runs on eight hits (including a homer) and a pair of walks with nine strikeouts. The team did not provide a timetable for his potential return.
With O’Day on the shelf, the Yankees bring back King, who has gone back-and-forth between Yankee Stadium and the alternate training site over the past two seasons. Altogether, King has compiled a 5.22 ERA/4.42 SIERA over 39.2 MLB innings. The 25-year-old has yet to allow a run through eleven frames of long relief this year, but his ordinary strikeout and walk rates (21.4% and 9.5%, respectively) are virtually unchanged from last season.
The Yankees are off to a 12-14 start, but that underwhelming performance hasn’t been the fault of the bullpen. New York relievers have league-best marks in ERA (2.24), SIERA (2.90) and K% minus BB% (22.7 points).
