Matt Barnes ended his 11-year big league career on Sunday, announcing his retirement after a run that began in Boston and finished with stops in the Marlins and Nationals. The pitcher, who was selected in the first round of the 2011 MLB Draft by the Red Sox, said on Instagram that baseball had given him more than he ever could have imagined.
That makes Barnes, 36, the latest former Red Sox arm to move from active player to ex-player, but his exit lands differently because so much of his career was tied to one uniform. He spent the first nine of his 11 seasons in Boston, reached the majors there as a September callup in 2014 and helped the Red Sox win the 2018 World Series with one run allowed over 8 2/3 innings across seven appearances, including two victories.
For Barnes, the numbers also explain why Sunday felt like a line being drawn. He was an All-Star in 2021 and finished that season with a 3.75 ERA over 60 appearances, showing the kind of late-career value teams still expected from him. But before the 2023 season he was designated for assignment, and early in the 2024 season that happened again before he elected free agency, a stretch that left him without a new landing spot as the season moved on.
In his retirement note, Barnes said there was not a single thing he would change when he looked back on his career. He thanked the Red Sox for believing in a kid from Connecticut, said wearing one of the sport’s most iconic uniforms would stay with him, and called winning a World Series in Boston and playing at Fenway Park memories he would carry for the rest of his life. He also pointed to his family, saying none of it would have been possible without their sacrifices, and the post came just two weeks after he and Chelsea Barnes shared a sonogram photo saying another child was on the way.
The retirement closes the book on a career that gave Barnes a championship, an All-Star selection and more than a decade in the big leagues, but it also leaves the next step open. He said he was excited for what was ahead, and for now the most lasting answer is that his baseball life ended the way it was built — with Boston at the center of it.
