Napoli felt mild tightness in his left groin Saturday and slowly worked his way back into the lineup.
"I had a little flare up," Napoli said. "It was sore but it’s spring training. They were being easy on it because I don’t need to be ready right now."
He worked on catching drills for the first time Thursday. Napoli said he tried to make an adjustment in his stance during the session. He tried to keep his feet straighter rather than tilting them toward his insoles.
"I get in a weird stance," Napoli said. "My legs get real low and my knees go together and it puts pressure on the groin."
Napoli said he's not sure how much of an impact the change will make but the injury is not a big deal.
*Pitcher Joe Beimel was sick for Thursday's game against the Oakland Athletics. He's feeling better Friday. Although he's back in camp, assistant general manager Thad Levine said he likely won't pitch until Saturday.
*Greg Miclat is not at camp Friday due to symptoms consistent to that of a migraine.
*Pitcher Justin Miller will not pitch in Friday's game due to mild back stiffness.
