Hill discloses bout with tendinitis

Skipper Trembley says left-hander is OK to pitch

BALTIMORE -- After arguably his most disappointing performance this season on Monday, an outing in which he lasted just 2 1/3 innings, Orioles lefty Rich Hill stood before members of the media and admitted he's been coping with tendinitis in his throwing shoulder.

"I don't know what to say, really," Hill said. "I have been having some issues with the shoulder and we have been doing a good job of keeping the fire down a little bit, and unfortunately it is something that I haven't been able to maintain any consistency with."

Despite the confession, Orioles manager Dave Trembley said before Tuesday's game the news regarding Hill's shoulder hasn't been a big enough problem to cause concern.

"Obviously if it was at such a point where he couldn't pitch, he wouldn't pitch," Trembley said. "But it's never been brought to my attention that he was not able to pitch."

With right-hander Chris Tillman expected to make his Major League debut Wednesday, the decision to send a current starter out of the rotation will come in the near future. Trembley said he would not formally name Tillman as the starter until after Tuesday's game, nor would he announce the corresponding roster move until before Wednesday's game.

Trembley said he hadn't spoken to Hill following the left-hander's start Monday but received the team's daily medical report and said Hill's shoulder tendinitis was listed.

Another possibility, however, is if Hill's injury to his shoulder is serious enough, he could be placed on the disabled list rather than sent to the Minors. When asked about the chances of Hill moving to the DL, Trembley said he hadn't spoken about it with Orioles president of baseball operations Andy McPhail.

Hill has been a disappointment for the Orioles this season. The southpaw is 3-3 with a 7.80 ERA in 14 games and has issued a team-high 40 walks.

But despite the injury, Trembley was quick to assure that Hill is still available to pitch.

"I haven't been told he's not," Trembley said. "No one has told me he's not able to pitch again."
