TORONTO — For at least the next couple of weeks, the Red Sox will be without one of their most important arms.
Reliever Garrett Whitlock landed on the injured list with right elbow inflammation Thursday, a day after he was unavailable because the pain — which had been building for a few weeks, he said — was such that he could not throw.
“Been throwing a lot and warmed up a lot, which has been a big thing. Tightened up on me after warming up [Tuesday] night,” Whitlock said Wednesday night. “Not as much on-and-off. It’s been building. I would say that’s probably the better word. So it’s just one of those things. I know [interim manager Chad Tracy has referred to Whitlock in recent weeks as ‘beat up’ from pitching a lot]. It was kind of gradually getting that way, and then it’s getting to a pretty big point.”
To replace Whitlock on the roster, the Red Sox brought righthander Greg Weissert back from Triple-A Worcester. He had been sent down last Friday amid a bullpen roster crunch. He did not appear in a game for Worcester.
Without Whitlock, the primary setup man for closer Aroldis Chapman, the Red Sox will have to lean more heavily on righthander Tyron Guerrero (who gave up five runs and recorded no outs Wednesday), lefthander Erik Miller (acquired from the Giants at the trade deadline), and righthander Justin Slaten.
Whitlock, who had Tommy John surgery in 2019 and an internal brace procedure in 2024, appeared in 13 games in a span of 27 days, including a four-day All-Star break. He also warmed up in the bullpen but did not enter on several occasions.
