Athletics pitcher Jarrod Parker refractured the medial epicondyle in his pitching elbow, the team announced Friday.
Parker, 27, hasn’t pitched in the majors since undergoing Tommy John surgery before the 2014 season. He fractured the medial epicondyle last year while pitching in a minor league rehab assignment. The medial epicondyle is part of the elbow joint and is connected to the unlar collateral ligament, the ligament repaired during Tommy John surgery.
On Thursday, Parker pitched to hitters for the first time this spring. He threw a pitch and began screaming in pain, according to reporters at the A’s facility.
In 2013, Parker’s last season in the majors, he had a 3.97 ERA and 1.223 WHIP in 32 starts.
