Guthrie unsure if he'll pitch Saturday

BALTIMORE -- The Orioles are still moving forward in the hope that staff ace Jeremy Guthrie will return to the mound Saturday, but the right-hander's cranky shoulder might not allow that to happen. Guthrie said Wednesday that he's not sure if he'll be able to make that outing, and he also said he doesn't know which day he'll throw his next bullpen session.

"We're just day-to-day," he said of the continued ambiguity regarding his recovery. "Take it each day and get ready."

Guthrie, who started 29 straight games and ranked among the league leaders in innings pitched at the time of his injury, has lost three straight starts and hasn't taken the ball since Aug. 29. The Orioles scratched him from one start with a tired arm and from the next with a case of tonsillitis, and Guthrie has experienced discomfort during a recent side session.

The Orioles have discussed shutting Guthrie down for the season but have decided against it for now. Guthrie will take the mound either Thursday or Friday to ascertain whether he can pitch Saturday, and the Orioles will adjust accordingly. Until then, Baltimore is content to pencil him in and monitor his recovery with the utmost scrutiny.

"It's getting better," said Guthrie, who has already reached a career high in innings with 186 2/3. "We're just working on it each day."

If Guthrie isn't able to go, the Orioles would likely replace him with either Lance Cormier or Dennis Sarfate.
