Arroyo still had plenty of evidence from Sunday's sixth-inning line drive off the bat of the Rangers' David Murphy. The stitches from the baseball were imprinted on the knuckle on the outside portion of Arroyo's hand. A red welt was visible on his left forearm.
"That's the ricochet. It's still there," Arroyo said. "I can't believe how hard that hit me."
Both Arroyo and manager Dusty Baker feared it was a serious injury initially as he exited the game. But X-rays taken were negative for any fractures.
"I heard it first, then when I saw it, he told me, 'That was it. It was broken,'" Baker said. "I saw the hand, and that's what I thought. We immediately went to, 'What are we going to do? What changes are we going to make? How long is he going to be out?' You start having all of those thoughts. And [Mat] Latos got hit on the leg the day before. It's like, 'Let's get out of here pretty soon.'"
Arroyo, who has never missed a game because of an injury throughout his whole professional career, is still on track to make his last spring start on Friday vs. Arizona.
"This guy takes pride in pitching and being able to pitch," Baker said. "I've only seen a few like him in my career -- very few, actually."
