He's calling it quits.

On Monday, ex-New York Mets and Yankees reliever Darren O'Day officially announced his retirement from Major League Baseball at 40-years-old via Twitter.

"It’s been a wild ride that I never thought I’d get to experience, but it’s finally time to hang ‘em up.

"As a lightly recruited high school player, to a college walk-on, to an undrafted free agent, to a non prospect entering pro ball, I am extremely proud of playing with the best players in the world for so long."

O'Day spent 15 years in the big-leagues and went 42-21 with a 2.59 ERA. The submariner played for a total of six teams, spending seven seasons with the Baltimore Orioles under manager Buck Showalter. In addition to Baltimore, O'Day played for the Los Angeles Angels, Mets, Yankees, Texas Rangers and Atlanta Braves.

The reliever was a Rule 5 Draft pick of the Mets in December of 2008. He spent two weeks with the Mets in 2009 before getting designated for assignment. He was later claimed by the Rangers.

O'Day's final two seasons were injury riddled. In 2021, he made just 12 appearances for the Yankees before undergoing season-ending left hamstring surgery. Last season, he signed a minor league deal with the Braves, but dealt with injuries for a majority of his campaign.
