Red Sox infielder Adalberto Mondesí has been halted from all baseball activities due to persistent soreness. This comes a day after reports of his progress in recovering from an ACL injury. Prior to this setback, Mondesí had been facing live pitching, running and taking ground balls. However, pain tolerance in his left knee remains a problem. Manager Alex Cora did not rule out a return this season but acknowledged that time is running out with just over six weeks remaining.

Mondesí has spent his entire first season with the Red Sox rehabbing at the team’s complex in Fort Myers and has suffered numerous setbacks since his ACL surgery in May 2022 while with the Royals. He was expected to be ready for Opening Day but lack of progress led him to be placed on the 60-day injured list at the start of the season.

In other injury updates, righty reliever Zack Kelly (elbow surgery) threw a 25-pitch bullpen in Fort Myers on Tuesday and is expected to face hitters next week at Fenway South; there’s a chance he could rejoin the bullpen in September.
