The Baltimore Orioles made one roster move Tuesday in what will likely be a busy week. Prior to Tuesday's game, Baltimore placed right-handed starter Daniel Cabrera on the disabled list with a strained lower back and promoted relief pitcher Chris Ray from Class AA Bowie. Ray was 0-3 with a 2.96 ERA in a previous stint with the Orioles.

"When we originally sent him down it wasn't because we didn't like him," Orioles interim manager Sam Perlozzo said. "We wanted him to go down and get things resolved with his delivery and freshen up his arm."

Part of the reason Ray had a tired arm was because the team didn't have a long man after the release of James Baldwin. Ray was thrust in a role of long relief, which wasn't what the team had wanted for him when they brought him up from Bowie on June 13.

"We used him an awful lot when we didn't have a long man," Orioles Executive Vice President Jim Beattie said.

Ray's return will coincide with Baldwin's return. The reliever was claimed off waivers Monday and will join the team Wednesday. It's uncertain at this point what the corresponding roster move will be. The team won't demote pitcher John Maine. The team could designate reliever Jason Grimsley for assignment.

The Orioles will also likely activate infielder-outfielder B.J. Surhoff from the disabled list Wednesday or Thursday. First baseman Alejandro Freire will likely be demoted to AAA Ottawa to make room for Surhoff. . . .

Rafael Palmeiro continued to be kept out of the starting lineup because of a sprained right ankle. Because of his injury and his suspension for testing positive for steroids, Palmeiro has played in just two of the past 20 games.
