Matt Barnes, a former All-Star reliever for the Boston Red Sox, has officially announced his retirement from Major League Baseball after an 11-year career. The 36-year-old expressed his gratitude for his time in the sport in a statement posted on Instagram.
"When I look back at my baseball career, there isn’t a single I would change," Barnes wrote. "I was able to live out not only my dream, but the dream of so many kids who pick up a baseball hoping one day they’ll hear their name called. For that, I’ll be forever grateful… baseball gave me more than I ever could have imagined."
Barnes was selected by the Red Sox in the first round of the 2011 MLB Draft following his collegiate career at UConn. He made his MLB debut with Boston in 2014 and became a reliable late-inning reliever for the team.
His most significant achievement came in 2018 when he was a key contributor to the Red Sox's World Series championship team. During that postseason, Barnes allowed just one run over 8 2/3 innings across seven appearances, earning two victories as Boston defeated the New York Yankees, Houston Astros, and Los Angeles Dodgers.
Barnes earned an All-Star selection in 2021, a season where he recorded a 3.75 ERA in 60 appearances. He also spoke fondly of his time in Boston.
"To the Red Sox organization. Thank you for believing in a kid from Connecticut," Barnes said. "You gave me the opportunity to wear one of the most iconic uniforms in sports, and I will always cherish that. Winning a World Series in Boston and experiencing Fenway Park as my home are memories I’ll carry the rest of my life."
After spending his first nine seasons with the Red Sox, Barnes was designated for assignment before the 2023 season. He subsequently played for the Miami Marlins and Washington Nationals. Barnes was again designated for assignment early in the 2024 season, after which he elected free agency but did not sign with another team.
Barnes thanked his family for their support throughout his career, acknowledging the sacrifices they made.
"Most importantly, to my family," he wrote. "Thank you for every sacrifice, every late night, every move, every setback, and every celebration. None of this would have been possible without your unconditional love and support. Baseball has given me lifelong friendships, incredible memories, and lessons I’ll carry forever. As one chapter closes, I’m excited for what’s ahead. Thank you, baseball. It’ll always be a part of who I am."
Barnes and his wife Chelsea are expecting their second child, having announced the news two weeks prior to his retirement announcement.
