The right-handed reliever spent nine seasons with the Red Sox before finishing his MLB career with the Miami Marlins and Washington Nationals. From First-Round Pick to Red Sox MainstayBorn June 17, 1990, in Danbury, Connecticut, Barnes was the 19th overall pick in the 2011 draft. He earned victories against the Houston Astros in the American League Championship Series and the Los Angeles Dodgers in the World Series. The Red Sox designated him for assignment before the 2023 season, and he was traded to the Miami Marlins. That makes the timing of Barnes' retirement significant as he did not announce his decision immediately after leaving the Nationals.
