The Nationals don’t believe Jordan Zimmermann will need to spend any time on the disabled list after an MRI of his right arm taken Saturday revealed only a biceps strain, no structural damage.
“I didn’t think it was bad, anything serious,” the right-hander told reporters Saturday night. “The MRI came back and looked pretty good. A little inflammation. Give it rest for a few days and go home and come back and start throwing on Thursday again.”
Zimmermann left his start Friday evening against the Phillies with was originally called a biceps cramp. He’ll return to his home in Auburndale, Wisconsin rather than attend the 2014 All-Star Game in Minneapolis, with Marlins starter Henderson Alvarez filling the vacancy on the National League pitching staff.
Zimmermann finished the first half with a 3.03 ERA, 1.21 WHIP, and 101/20 K/BB ratio in 113 innings.
