Britton announced his retirement from professional baseball Monday, Brittany Ghiroli of The Athletic reports.
Arm injuries limited Britton in the last few seasons of his career, but he had a seven-year stretch as one of the best relievers in baseball, posting a 1.84 ERA, 1.05 WHIP and 347:133 K:BB over 367.1 innings from 2014 through 2020. The southpaw saved 153 games over that stretch, made two All-Star teams and finished fourth in the American League Cy Young Award voting in 2016.
