When the New York Mets announced the 2020 season would include the retirement of Jerry Koosman’s number 36, there was some debate as to whether or not the best lefty starter in franchise history deserved it. The Mets have been careful about which numbers they retire. Heading into 2020, the only two players in franchise history who have been bestowed with the honor are Tom Seaver and Mike Piazza.
Naturally, it seemed David Wright would be the next to have his number retired. It’s unusual for a team to go back as far as they are with Koosman.
