Per the Mets, "a typical return to play" for the type of procedure Peterson had is six-to-seven months.
Peterson, who had a solid finish to the 2023 season after an uneven start that resulted in him being demoted to Triple-A Syracuse, was expected to be a valuable part of New York's rotation depth entering 2024, but his ability to contribute will now be delayed.
A six-month timeline would mean a return around the second week of May, while a seven-month timeline would mean Peterson not being back on a big league mound until after Memorial Day.
President of baseball operations David Stearns said on Tuesday that starting pitching would be among his top priorities this offseason, with the team expected to add two or three starters from outside the organization.
However, Stearns left open the possibility that the final spot in the rotation -- whether it's a five-or six-man rotation -- could be decided by an internal competition in spring training.
As far as Tylor Megill, he could perhaps be better suited for a relief role.
