Boston Red Sox relief pitcher Zack Kelly (elbow) worked a scoreless inning of relief on Friday during his minor league rehab appearance with Single-A Greenville. The 28-year-old reliever injured his elbow back in mid-April and looked to be done for the season at the time. He's slowly worked his way back and now has a chance to log some big-league appearances before the 2023 campaign is over. Kelly posted a 3.68 ERA, 1.64 WHIP, and 6:6 K/BB ratio over just 7 1/3 innings (six appearances) before sustaining the injury back in April. He'll likely need a few more rehab appearances throughout the minors before he's ready to join the Red Sox.

Boston Red Sox relief pitcher Zack Kelly (elbow) was transferred to the 60-day injured list on Sunday. The 28-year-old had been on the 15-day IL after exiting Wednesday's meeting with the Tampa Bay Rays because of right elbow inflammation. But he'll now need to see a specialist, which is never an encouraging sign. Kelly had a 3.68 ERA and six strikeouts in six games before succumbing to the injury. However, his current ailment appears worse than initially anticipated, so he'll spend more time on the shelf.

Boston Red Sox right-hander Zack Kelly left a relief appearance against the Tampa Bay Rays on Wednesday with pain in his right elbow. Kelly got two outs in the fifth inning, allowing two runs on two hits while striking out one and walking one before departing. The 28-year-old has a 3.68 ERA over 7 1/3 innings of work in 2023. Look for the team to offer updates on Kelly's elbow after the conclusion of Wednesday's game.
