Six-time All-Star outfielder Ryan Braun announced his retirement Tuesday.

Braun, 37, played his entire 14-year career with the Milwaukee Brewers (2007-20). He was the National League Rookie of the Year in 2007 and the league's Most Valuable Player in 2011.

The Brewers posted a video message from Braun on Twitter.

"Today, more than 14 years after I first took the field as a Milwaukee Brewer, I've decided to retire," he said. "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.'"

Braun batted .296/.358/.532 with a franchise-record 352 home runs, 1,154 RBIs and 216 stolen bases in 1,766 games.

He led the National League with 203 hits in 2009 and with 41 homers and 108 runs scored in 2012.

In July 2013, Braun was suspended without pay for the remainder of the season for violating the league's policy on performance-enhancing drugs. He later admitted to using banned substances while rehabbing an injury and issued an apology.

Braun helped the Brewers reach the playoffs five times. He reached the National League Championship Series twice, losing to the St. Louis Cardinals in 2011 and the Los Angeles Dodgers in 2018.

"Ryan brought us many unforgettable moments on the field; from playoff-clinching, dramatic home runs to nearly 2,000 career hits, he is unquestionably one of the greatest players in Brewers history," team chairman Mark Attanasio said in a statement.

Milwaukee drafted Braun with the No. 5 overall pick in 2005. The Brewers declined his $15 million option for the 2021 season and made him a free agent last October.
