Hundley said he felt pain in his arm in the third inning on Saturday. By the eighth inning, he was taken out of the game and by the end of the game, he couldn't straighten his arm.
The diagnosis? Hundley had fluid buildup in his right elbow due to an irritated tendon. He had an MRI on Monday and it showed no structural damage.
"Definitely a relief," said Hundley, who missed 31 games earlier this season with a strained right oblique.
Doctors gave Hundley a cortisone shot and told him that he could make a "safe" return by Friday. Hundley is hoping for earlier.
"For me, I want to be back in there Wednesday," Hundley said. "Let it calm down today, let the cortisone work tomorrow and then hopefully get back in there Wednesday, if [Padres manager] Buddy [Black] will put me in the lineup."
Hundley was able to extend his arm and move it after doctors drained his elbow.
He hadn't been able to do that over the weekend.
"I couldn't brush my teeth, I had to do that left-handed," Hundley said. "I couldn't shower. It was, all of a sudden, I couldn't bend my arm."
