TORONTO — Toronto Blue Jays general manager J.P. Ricciardi says he's willing to listen to offers for ace Roy Halladay.

"I don't think anything has changed, I just think, 'You know what, why not listen? The worst we can say is no,' " Ricciardi told The Canadian Press yesterday.

"If someone wants Roy and they're willing to blow us away, we'd be willing to listen, that's all I'm saying. That doesn't mean we'd trade him, that doesn't mean we're looking to trade him. All it means is we'd be willing to listen."

Halladay is 10-2 with a 2.79 ERA in 16 starts. He'll be paid $14.25 million this year and his contract expires after the 2010 season, when he's set to earn $15.75 million.

"In the past we weren't willing to listen and we figured let's just see what someone's got out there and what someone is willing to offer," Ricciardi said.

The Blue Jays are 43-42, eight games back of Boston in the AL East.

Ricciardi was vague when asked if salary would be a factor. The Blue Jays' payroll is just short of $81 million, 16th out of 30 big league teams.

"I'm not so sure payroll-wise where we're going to be able to be after 2010. I'm not so sure that the player wants to stay here beyond 2010. I'm not sure of those things," he said. "So those are all things we have to weigh out. He's under contract through next year and worst-case scenario, he does not sign back with us and we get two draft picks."

CARDINALS' DEROSA ON DISABLED LIST

St. Louis is placing utilityman Mark DeRosa, acquired last month from Cleveland, on the 15-day disabled list, retroactive to July 1, because of a strained left wrist.

The Cardinals also said that infielder Brian Barden and outfielder Nick Stavinoha are being recalled from Triple-A Memphis. St. Louis is sending infielder Tyler Greene to Memphis.

DeRosa got off to a stuttering start with the Cardinals, going 0 for 9 in three games after batting .270 with 13 homers and 50 RBIs with Cleveland.

D-BACKS DEAL PENA TO WHITE SOX

The Arizona Diamondbacks have traded right-handed reliever Tony Pena to the Chicago White Sox for minor league infielder Brandon Allen.

Pena was 5-3 with a 4.24 ERA in 37 games for the Diamondbacks this season. He was 16-13 with a 4.08 ERA in 209 career games with Arizona. He began the season as the team's top setup man but had struggled in recent weeks, especially against left-handed hitters.

Allen, 23, split time this season with Double-A Birmingham and Triple-A Charlotte, hitting a combined .281 with 16 doubles, three triples, eight homers and 43 RBIs.

DODGERS' BELISARIO TO HAVE ELBOW TESTED

Dodgers reliever Ronald Belisario is going back to Los Angeles for tests on his painful right elbow.

Belisario left the team before last night's series opener against the New York Mets.

Belisario made his major league debut this season and leads the team with 43 appearances. He is 1-2 with a 2.42 ERA. The right-hander had pitched 13 2/3 straight scoreless innings before a rough outing Saturday at San Diego.
