Putnam missed the entire 2018 season while recovering from Tommy John surgery, but it was the hamstring issue that prevented him from making an appearance during the Grapefruit League. He'll likely stick around at extended spring training to rehab the injury before reporting to Triple-A Pawtucket.

Putnam suffered the injury while participating in a drill at the beginning of March, although it's unclear as to when he might return to the mound. "He's feeling better," manager Alex Cora stated. "He's playing catch. He hasn't been able to get back on the mound." While Putnam wasn't expected to win a roster spot entering camp, this injury will make doing so nearly impossible. He should begin the 2019 campaign with Triple-A Pawtucket when healthy.

Putnam had been scheduled to pitch Friday but was removed from the team's travel roster as a precaution. The non-roster invitee is not expected to earn a roster spot.

Putnam missed the entire 2018 season while recover from Tommy John surgery that he underwent in June 0f 2017. The right-hander should be fully healthy for spring training, where he'll compete for a spot in Boston's Opening Day bullpen. Putnam has proven to be an effective reliever over parts of seven major-league seasons, posting a combined 3.20 ERA and 9.6 K/9 across 152 career innings.
