The Mets have not approached outfielder Brandon Nimmo about a potential extension, despite his apparent willingness to stay in New York, per Tim Healey of Newsday (via Twitter). Nimmo will reach free agency after this season, his age-29 season. Nimmo is an on-base machine when healthy, but he’s only once appeared in more than 100 games in a season.
It’s certainly possible that New York is ready to let Nimmo walk after the season. The Mets proved their willingness to take a hard line with departing free agents with Michael Conforto, Nimmo’s longtime running mate in the outfield. Conforto remains a free agent now.
Furthermore, this winter’s signings of Mark Canha and Starling Marte protect New York somewhat against Nimmo’s potential departure. Center fielders are in short supply leaguewide, which could make Nimmo an intriguing target despite his injury history. And the duo of Marte and Canha don’t perhaps carry enough glove to man the position full-time. But they ought to be enough to provide the Mets leverage in a potential Nimmo negotiation. According to Nimmo’s comments, however, that discussion is entirely hypothetical.
When healthy, Nimmo has been a first-class performer, posting a 135 wRC+ for his career and roughly 4.4 fWAR per 600 plate appearances. On the other hand, Nimmo’s never actually had 600 plate appearances in a season. Therein lies the issue facing the Mets in deciding whether or not to offer Nimmo a long-term deal.
