The St. Louis Cardinals obtained T.J. McFarland midway through last season to help settle their bullpen. His performance earned him a contract for the 2022 season.
McFarland signed a one-year deal, the team announced Monday.
McFarland, 32, went 4-1 with a 2.56 ERA in 38 relief appearances. The left-hander joined the club on July 1 and from that point on induced 12 double plays, which tied for most among MLB relievers during that span and was a post-All-Star break record for Cardinals relievers.
More on McFarland's groundball effectiveness: His career 63.4% groundball percentage ranks sixth among relievers since 1987. Among active relievers, only Zack Britton (76.5%) has been better during that span. His career ratio of grounded into double plays per nine innings pitched ranks sixth among relievers since 1974 and ties Brandon Kintzler for highest among active relievers.
McFarland previously pitched for Baltimore, Arizona and Oakland.
