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.

The New York Mets and San Francisco Giants agreed to a four-player swap on Thursday, just more than 24 hours away from Major League Baseball's trade deadline, that centered around veteran reliever Tyler Rogers.

The Mets are reportedly acquiring St. Louis Cardinals closer Ryan Helsley, according to ESPN's Jeff Passan, in exchange for a trio of prospects: Shortstop Jesus Baez (the team's No. 8 overall prospect ), pitcher Nate Dohm (No. 14) and pitcher Frank Elissalt.
