Even if he has the procedure, Pomeranz is expected to be ready by Spring Training.
"We'll let him sit down and determine if it's something he wants to do at this stage," head trainer Nick Paparesta said, "or just let it calm down."
Pomeranz posted a 2.61 ERA in 44 relief appearances compared to a 4.63 ERA in nine starting assignments. He will be considered for both roles come Spring Training.
• Though currently shut down to alleviate shoulder tendinitis, right-hander A.J. Griffin is also anticipated to be a full go by Spring Training after pitching in just two games for Triple-A Nashville this year.

• Melvin said catcher Josh Phegley (concussion symptoms) has greatly improved in recent days and should have no issues going into Spring Training.
