With trade talks swirling, the Baltimore Orioles' most significant addition to their rotation may come Monday, when Erik Bedard makes his long-awaited return from the disabled list.

Bedard, who went on the disabled list on May 26 with a sprained left knee, will pitch for the first time since May 21. At the time of his injury, Bedard was second in the league with a 2.08 ERA. He pitched a total of seven innings in two minor league rehabilitation starts before the Orioles determined he was ready to return. In those two starts, Bedard allowed two runs and struck out 13.

The Orioles expect Bedard to throw between 80 and 90 pitches.

"A lot of it has to do with stamina," Orioles Manager Lee Mazzilli said. "He's gone five innings. He can go five-to-six innings or longer."

Pitching coach Ray Miller said Bedard has looked healthy this week.

"He's thrown on the side outstanding for me," Miller said.

Bedard declined to speak until after his outing on Monday. Mazzilli said he did not know what the corresponding roster move would be. Because of a possible trade, the Orioles might not know their roster situation until just prior to the game.

Rookie Ray Is Okay

Mazzilli does not expect rookie Chris Ray to experience any emotional carryover after the reliever allowed the winning run in Saturday's loss.

"His makeup is really good," Mazzilli said. "I saw him after the game and it seemed he wasn't dejected." . . .

Rafael Palmeiro's solo home run in the second inning Sunday gave him a career total of 52 against the Seattle Mariners, which is the most by any player. . . .

Left-handed reliever Steve Kline pitched for the first time since July 8. He allowed three hits and a run.

Erik Bedard is set to return to the O's rotation for the first time since May 21.
