Helsley, 31, has been one of the game's best closers since moving into the role for St. Louis in 2022. With a high-octane fastball and untouchable slider, he's posted 103 saves and a 2.03 ERA with 266 strikeouts in 203 2/3 innings during that time.

New York sent relief pitcher José Buttó, outfield prospect Drew Gilbert and pitching prospect Blade Tidwell to the San Francisco Giants in exchange for Rogers. The Mets also dealt shortstop Jesus Baez as well as right-handers Nate Dohm and Frank Elissalt to the St. Louis Cardinals for Helsley.
