Milwaukee Brewers left fielder Ryan Braun is officially retiring from Major League Baseball.

He made the announcement Tuesday morning on the Brewers Twitter account.

"Today, more than 14 years after I first took the field as a Milwaukee Brewer, I've decided to retire," Braun said in a video. "While it's impossible to summarize my emotions, what I feel most is one, simple thing – gratitude. I just wanted to take a moment to say 'thank you.'"
