The 2018 season marked the first time since 1992 that both the Mets and the Yankees had new managers to start the season. The Yankees parted ways with Joe Girardi after they lost in the 2017 ALCS to the eventual champion Houston Astros, and was replaced as skipper with 2003 ALCS hero Aaron Boone; Mets manager Terry Collins announced his retirement and moved into the team's front office after the season ended. Mickey Callaway, former pitching coach for the Cleveland Indians, took over as Mets manager.
