New York Yankees left-hander CC Sabathia, who is retiring at the end of the season, left Game 4 of the American League Championship Series with a shoulder injury, marking what appears to be the end of his stellar career.

Sabathia left the game in the eighth inning to a standing ovation at Yankee Stadium, and the salutes poured in on social media as well.

If that's the last pitch we see you throw in a big league game @CC_Sabathia thank you for all the years and memories. From the dominance with the @Indians to the run with @Brewers to the leadership with the @Yankees...cheers to you. One of the best to ever do it.

.@CC_Sabathia is a true warrior. Throwing until he couldn't and then trying again. Baseball is life and he showed it right there. #Hero #MyBrother #NothingButRespect

Best teammate I ever had. Gave everything for his first pitch to his last. Thank you CC

CC Sabathia is baseball's active leader in: wins, losses, games started, complete games, innings, hits allowed, earned runs, homers allowed, walks, strikeouts, and batters faced, among other things. Hell of a career, if it just ended. pic.twitter.com/5KRyZc4L2X
