Yet another sign of the Orioles' apparent disarray came when Baltimore made three roster moves prior to Tuesday night's game against the Tampa Bay Devil Rays.

Pitcher Sidney Ponson (strained right calf) and outfielder B.J. Surhoff (strained left groin) were placed on the 15-day disabled list and reliever Chris Ray was optioned to Class AA Bowie. In their place, the Orioles called up pitcher Eric DuBose from Bowie and first baseman Alejandro Freire and reliever Aaron Rakers from AAA Ottawa. Neither Ponson nor Surhoff is expected to miss a significant amount of time.

DuBose, who has spent the season at Bowie compiling an 8-10 record with a 3.25 ERA, will act as the team's long man in relief. For the moment, the Orioles will use a four-man rotation, then possibly call up starter John Maine this weekend.

"We'll make a decision along the way when we get there," Orioles Executive Vice President Jim Beattie said.

Last season DuBose began the season in the starting rotation but ended the season on the DL with bone chips in his elbow. DuBose said he had been waiting all year for an opportunity to pitch in the majors again.

"It's not something you can sit and dwell on," he said. "It's always frustrating because you know where you want to be and know where you belong."

Rakers was 5-4 with seven saves and a 2.48 ERA with Ottawa. Freire, signed as a minor league free agent in spring training, hit .299 with 19 home runs and 69 RBI for Ottawa.
