KANSAS CITY, Mo. -

There is one place a pitcher never wants to be sent: on a visit to Dr. James Andrews.

That, however, is the plight of Rays left-hander Matt Moore, who was placed on the disabled list Tuesday with a left elbow injury.

After a MRI exam was inconclusive Tuesday, Moore will be examined by Andrews on Wednesday.

"Anytime a pitcher goes on the DL and goes to see Dr. Andrews, you are concerned," Rays general manager Andrew Friedman said. "We'll be concerned until we're told not to be concerned."

Moore won 17 games last year, but he missed 31 games with an elbow injury. He left in the fifth inning Monday against the Royals, grimacing after throwing a 1-2 changeup for a ball to right-fielder Norichika Aoki.

Moore's pain did not go away Tuesday.

"The severity has jumped from what I was feeling," Moore said. "It's frustrating."

Surgery remains a possibility.

"Nothing is ruled out until he has a more thorough exam," Friedman said. "He'll have his elbow examined and they'll use a dye and look inside his elbow. ... We are waiting with baited breath."

Manager Joe Maddon was cautiously optimistic but acknowledged Moore's elbow was "worse than what we thought before."

"We'll have further tests with Dr. Andrews, and it might end up being better than we thought," Maddon said. "We just don't know. We're going to gather info, be patient and make an informed, unemotional decision."
