3) NY Mets traded Michael Fulmer in their package for Yoenis Cespedes
When the Mets traded Michael Fulmer in 2015 he had yet to make it to the big leagues. It was a necessary move. The team found themselves in the thick of a playoff chase. In need of a power bat, rumors of the Mets landing Gomez from the Brewers led to the moment where Wilmer Flores was brought to tears on the field. That deal never went through. Instead, the Mets turned their attention to the Detroit Tigers.
In exchange for Luis Cessa and Michael Fulmer, the Mets picked up Yoenis Cespedes. A catalyst for their 2015 postseason run, his stay in Queens was headline-grabbing and short-lived. For the 2015 season, it was almost perfect.
Fulmer would go on to win the 2016 Rookie of the Year with Detroit. The next year he was an All-Star. Things began to change for him in 2018 when he struggled throughout the year. Injuries knocked him out of the entire 2019 campaign. He was horrific in the shortened 2020 season.
Fulmer almost pitched himself off of a list like this until he made the move to the bullpen. Since 2021, he has quietly become one of the more effective late-inning relievers in baseball. He’s even someone the Mets should consider adding in the future. Hopefully, if they do, it yields better results than when Gomez came back.
