Before opening a three-game series against the Reds at Fenway Park on Tuesday night, the Red Sox made a pair of roster moves pertaining to their bullpen.
Boston placed right-hander Corey Kluber on the paternity list and recalled left-hander Ryan Sherriff from Triple-A Worcester, the club announced.
Kluber and his wife, Amanda, recently welcomed the birth of their fourth child. The 37-year-old must now remain on the paternity list for at least 24 hours, but no more than 72 hours. In other words, he is eligible to be reinstated on Wednesday at the earliest and by Friday at the latest.
Signed to a one-year, $10 million deal back in January, Kluber was Boston’s Opening Day starter to begin the 2023 season. But the veteran righty struggled to a 6.26 ERA (6.60 FIP) with 34 strikeouts to 18 walks in his first nine starts (41 2/3 innings) for the club.
Taking those difficulties into consideration, Kluber was removed from the starting rotation and demoted to the bullpen last week ahead of Garrett Whitlock’s return from the injured list. He has yet to pitch in relief for the Sox, which is something he has not done in a regular season game since 2013.
Sheriff, meanwhile, is back with the Red Sox for the second time this season after initially having his contract selected from Worcester earlier this month. The 33-year-old southpaw made two appearances on back-to-back days against the Mariners on May 16 and 17, marking his first big-league action since 2021. He tossed a scoreless frame in each of those games and recorded one strikeout.
With the WooSox this year, Sherriff has forged a 2.79 ERA and 3.57 FIP with 21 strikeouts to nine walks over 18 outings spanning 19 1/3 innings of work. He joins Joely Rodriguez as the only other lefty available to manager Alex Cora out of the Red Sox bullpen for the time being.
