Cavalli (elbow/arm) will throw a 20-to-25 pitch bullpen session Tuesday, Bobby Blanco of MASNSports.com reports.
The bullpen session -- which will feature all fastballs -- will be his first time throwing off a mound since he had to be pulled off his rehab assignment in mid-July due to a "dead arm" phase. Cavalli had made three rehab starts in the lower minors as he works his way back from May 2023 Tommy John surgery. It's going to take a while for him to get ramped back up, and it's not clear whether the 26-year-old will have a shot to make it back before the end of the season.
