In that time he posted an excellent 2.66 ERA, 0.89 WHIP, and 572/78 K/BB ratio in 480.2 innings and notched 95 saves. He won a World Series ring with the Red Sox in 2013 and was an All-Star in 2014. Uehara’s last big league stint in America with the Cubs in 2017, for whom he posted a 3.98 ERA (111 ERA+) in 49 games.
Happy trails to an excellent reliever.
