The Boston Red Sox received the worst news you can hear about any pitcher. Carson Smith needs Tommy John ligament replacement surgery in his right elbow and will be out the rest of this season and likely half of 2017. This was not what this injury seemed to be in Spring Training.
In March, when the arm injury was first diagnosed, it was called flexor tendonitis in the forearm. It seemed that Smith was back to his 2015 form (2.34 ERA, 92 strikeouts in 70 innings) when he came back to the team on May 3 and threw a scoreless inning in Chicago.
