Feeling ill, Napoli back in Boston undergoing tests

BALTIMORE -- Mike Napoli was sent back to Boston on Saturday for tests to see if the Red Sox can find an answer to the puzzling illness that's bugged him the past few days.

Following a 5-4 win over the Orioles, manager John Farrell described Napoli's situation as "general illness." The Sox have gotten preliminary tests completed, but Farrell didn't have results and they're still hoping to find out what's making Napoli ill.

"We've got a virus running through the club," Farrell said prior to the game. "We had a couple of guys throwing up yesterday that still played, but because this is persistent since the other night, we want to be sure that he's in a safe place, and we can get to the bottom of it."

The Red Sox had to pull Napoli in the third inning of Thursday's loss to the Orioles due to the dizziness, nausea and light-headedness. It improved a little in the past two days, but Boston's looking for answers.

Farrell said the team's pretty sure this is not concussion-related, but they don't have the final answer just yet.

"He's going to see our internist and then any kind of recommendation they'll make for follow-up, he'll do," Farrell said.
