Melton exited Sunday's 8-1 loss to the White Sox in the fourth inning with right arm discomfort, Jason Beck of MLB.com reports.
Melton left the game after recording two outs in the bottom of the fourth frame, and his removal from the contest is now understood to have been due to arm discomfort. Manager A.J. Hinch outlined that Melton was dealing with some "achiness" in his right arm, and the pitcher will undergo further examination in the near future.
