Dr. Mark Schickendantz performed an arthroscopic shoulder debridement at the Cleveland Clinic in order to remove inflammation from Tomlin's AC joint. Cleveland announced that the right-hander is expected to miss around three to four months while rehabbing from the procedure.
The 30-year-old Tomlin, who is on the 15-day disabled list, indicated at the end of Spring Training that he experienced discomfort in his throwing shoulder over the offseason. The issue lingered throughout the spring, when Tomlin was trying to compete for a spot in Cleveland's rotation.
Tomlin posted a 4.76 ERA in 25 games (16 starts) for the Indians last season and has gone 29-28 with a 4.89 ERA in 85 games in parts of five seasons with Cleveland.
"It sounds like it went really well," Francona said of the surgery. "Schick was pretty confident that he could get in and do what he needed to do, and get him on his way to his recovery."
