The chances of the Mets finishing the winter with a big splash were slim in recent weeks, and they may have disappeared altogether with Monday’s trade that sent Starling Marte from the Pirates to the Diamondbacks.

Marte was strong on the Mets’ radar at the winter meetings, but discussions with the Pirates had dissipated in recent weeks. In December, the teams had discussed a deal that likely would have included Brandon Nimmo.

The Mets backed off, according to sources at the time, because they didn’t believe they would be receiving equal value for Nimmo, a first-year arbitration eligible player who will earn $2.18 million this season. The 31-year-old Marte will earn $11.5 million this season. His contract also contains a club option for 2021 worth $12.5 million.

The Pirates received two prospects from the Diamondbacks for Marte and $250,000 in international signing bonus pool money. The Mets targeted Marte as somebody who would bring a right-handed bat with power to the center-field equation. Marte, who won Gold Gloves for the Pirates in 2015 and ’16, posted an .845 OPS last season.

So, the Mets appear headed to spring training with an outfield that includes Nimmo, Michael Conforto, J.D Davis, Jake Marisnick, Dominic Smith and potentially Yoenis Cespedes.

Marisnick arrived in a trade with Houston as a right-handed bat and strong defensive player who Mets officials believe will be an upgrade on Juan Lagares. It’s likely Marisnick will get a chance to play against most lefty starters and serve as a late-inning defensive replacement.

The wild card is Cespedes, who missed the past 1 ½ seasons recovering from double heel surgery and multiple ankle fractures, which he sustained eluding a wild boar on his ranch. Cespedes has been working out in Port St. Lucie, taking batting practice and running, but it’s unclear to what extent he will be ready for the start of spring training. Davis and Smith are the other possibilities in left field. Both had breakout seasons for the Mets in 2019, but appear relegated to part-time roles given that Pete Alonso and Jeff McNeil have the corner infield positions anchored.

In a relatively quiet winter, the Mets have added Rick Porcello, Michael Wacha and Dellin Betances through free agency, bolstering the starting rotation and bullpen. Porcello and Wacha could be battling for one spot in the rotation, although it’s also possible Steven Matz will have to win a starting job in spring training.

Betances, who barely pitched last season with the Yankees because of shoulder problems and a torn Achilles, has maybe the highest upside of the new arrivals. The right-hander pitched to a 2.70 ERA in 66 appearances for the Yankees the previous season.

Eduardo Nunez received a minor league contract from the Mets and will get a chance to make the club in spring training, according to an industry source. Nunez posted a .548 OPS in 60 games for the Red Sox last season.
