Following the Cubs' season-ending Game 4 loss to the Mets in the NLCS, Haren tweeted that he “took his jersey off for the last time.” ESPN's Jesse Rogers had previously reported that Haren would retire following the 2015 season.
Haren, 35, made his MLB debut for the St. Louis Cardinals in 2003 and went on to play for eight different teams through thirteen seasons. He made the All-Star Game in three straight seasons from 2007 to '09 as a member of both the Oakland Athletics and Arizona Diamondbacks.
Haren was traded from the Miami Marlins to the Cubs at the 2015 trade deadline, where he posted a 4.01 ERA in 11 starts.
Haren recorded 153 wins during his career with a 3.75 ERA over 2,419 2/3 innings and 391 games.
