Nearly all of the hand’s tiny muscles are controlled by the ulnar nerve, which sends sensory information to assist move the shoulders, arms, and hands. Although it originates in the armpit, it is not functional until it reaches the forearm.
This may explain Meyer’s recent atypical performance. After beginning his Triple-A season with a 1.72 ERA (31 1/3 IP, 6 ER) over his first six starts, he allowed 14 runs in only 8 1/3 innings during his next two. That includes a career-low 3 1/3 innings against Durham on Tuesday.
The Marlins granted Cody Poteet a spot start on Tuesday and recalled Daniel Castano, who was supposed to pitch that day for Jacksonville, after Jesús Luzardo was placed on the Major League disabled list over the weekend. This resulted in Meyer’s start being delayed by four days for the second time this season. Meyer reported the problem to the trainer on Wednesday, after which he was tested.
