The Royals have placed right-hander Jesse Hahn on the 10-day injured list due to right shoulder impingement syndrome, the team announced. Righty Jake Newberry has been called up from the alternate site to take Hahn’s spot in the Kansas City bullpen.
It isn’t yet clear how long Hahn might be out of action, though manager Mike Matheny told reporters (including MLB.com’s Anne Rogers) that Hahn will miss “some time” with the injury. According to Matheny, Hahn felt a shoulder issue while warming up for an appearance yesterday against the White Sox, though he didn’t tell team trainers or coaches about the problem until after the game. Hahn was clearly affected by the injury — he issued a walk, a two-run homer to Adam Eaton, and then another walk before being removed from the game without a single batter retired.
Hahn is unfortunately no stranger to arm injuries, having undergone a Tommy John surgery and another UCL repair procedure already on his record. Thanks to that latter surgery, he has pitched only 25 1/3 Major League innings pitched since being acquired by K.C. in January 2018.
Hahn posted an 0.52 ERA/3.93 SIERA over 17 1/3 innings in 2020, though benefited from quite a bit of batted-ball luck (an absurdly low .108 BABIP). The Royals were counting on the 31-year-old to serve in a setup or high-leverage role this season, though Hahn had posted an 8.10 ERA and looked shaky over 3 1/3 innings even prior to Sunday’s disastrous outing.
