It marks the second time that Petry, 32, has been traded by the Tigers. They traded him to the California Angels after the 1987 season for outfielder Gary Pettis. He returned to Detroit as a free agent before the 1990 season.
"I've got to look on this as an opportunity," Petry said. "But it's hard to understand why me. I love Detroit so much. I'd still like to work for the organization."
* BRAVES: First baseman Sid Bream, who missed most of the 1989 season after surgery on his right knee, will need another operation on the same knee. But he hopes to put it off until after the season.
Bream underwent a test Monday that revealed a bone fragment in the right knee. He reinjured the knee June 18 and has not played since.
Bream hopes to play tonight if there is no swelling in his knee. If the knee continues to cause problems, Bream would need arthroscopic surgery to have the bone fragment removed and would miss at least two weeks.
* PHILLIES: Outfielder Lenny Dykstra is with the team in St. Louis, his first road trip since he was injured in a car accident May 6.
"There's not a lot to talk about, really," Dykstra said after an afternoon workout at Busch Stadium. "All I'm doing is running, lifting light weights and throwing and playing a little bit of pepper."
Dykstra hopes to be ready to play again July 11, the day after the All-Star break.
* MARINERS: A New York investment bank has agreed to put off repayment of a $40 million loan until the economy improves, according to club owner Jeff Smulyan.
* ALL-STAR GAME: President Bush will travel to Toronto on July 9 to attend the All-Star Game and confer with Canada Prime Minister Brian Mulroney on the economic summit of seven industrialized nations. Bush will attend the game with Mulroney.
