McCann finishes his career as a seven-time All-Star, six-time Silver Slugger Award and one-time World Series Champion with the Astros in 2017.
He announced his retirement Wednesday evening to the media after the Braves lost Game 5 of the NLDS 13-1 to the St. Louis Cardinals, ending their season.
McCann was a key contributor to the Astros' 2017 championship run, hitting that pivotal home run in Game 5 of the World Series, which many remember. He also had key RBI doubles in Games 6 and 7 of the ALCS against the New York Yankees, his team prior to the Astros.
McCann spent the majority of his career with the Braves, playing in Atlanta from 2005-2013 and again in 2019.
