2) David Robertson
David Robertson was more recently a Met than a Yankee, but he began his career in the Bronx. Robertson spent each of the first seven years of his career with the Yankees, eventually taking over as the team's closer for the great Mariano Rivera. From there, he'd make a whole bunch of stops pitching late in games before eventually signing with the Mets ahead of the 2023 season.
As a Met, Robertson was everything they could've hoped. He had a 2.05 ERA in 40 appearances and 44 innings pitched serving as the team's primary closer with Edwin Diaz out. Robertson did struggle after New York shipped him off to Miami at the trade deadline, but his strong finish (1.74 ERA in September) helped the Marlins make an unlikely postseason appearance.
Whether Robertson would seriously entertain coming back after the Mets traded him remains to be seen, but he'd be a nice fit once again. This team needs to bring in several relievers as other than Edwin Diaz, Brooks Raley, and Drew Smith, it's hard to know who will even be on the Opening Day roster.
He might be 38 years old, but Robertson clearly has something left in the tank. The Mets bringing him back for another season to help a depleted bullpen in the vision they had thought of before the 2023 season as Edwin Diaz's set-up man would be wise.
