San Diego traded infielder Damian Jackson and catcher Matt Walbeck to Detroit on Saturday for catcher Javier Cardona and outfielder Rich Gomez.
Jackson hit .241 with four home runs and 38 RBIs and stole 23 bases last season.
"When a trade like this happens, you have to look at it like somebody wanted you, not that you weren't wanted because you'll drive yourself crazy," Jackson said. "We'll see."
Walbeck, 32, spent almost the entire 2001 season in Triple A. He singled for Philadelphia in his only major-league at-bat.
Cardona, 26, hit .260 with one homer and 10 RBIs in 46 games for the Tigers. Gomez, 25, hit .269 with 14 homers, 44 RBIs and 26 stolen bases for Double-A Erie.
Also, the Padres announced right-hander Kevin Jarvis will start the season opener.
Dodgers, Expos make deal
JUPITER _ In a swap of right-handed relievers, Los Angeles sent Matt Herges to Montreal for Guillermo Mota.
The Expos also got minor-league infielder Jorge Nunez, and the Dodgers received minor-league outfielder Wilkin Ruan.
Herges, who turns 32 on April 1, was 9-8 with a 3.44 ERA and one save for the Dodgers, working 99 innings in 75 games. Mota, 28, pitched in 53 games last year, going 1-3 with a 5.26 ERA in 49 innings.
CUBS: Closer Tom Gordon had full range of motion when he met with Michael Schafer, the team doctor. Gordon, who tore a muscle in his shoulder earlier this month, is doing strengthening exercises, but it's still too early to put a timetable on his return. outfielder Moises Alou sat out his fourth game with a sore muscle in his side. He should return in a few days.
EXPOS: Right-hander Troy Mattes and third baseman Fernando Tatis were put on the 15-day DL. Mattes has been out since Feb. 16 with right shoulder tendinitis. A right shoulder strain and patellar tendinitis in his right knee have idled Tatis since last season. shortstop Orlando Cabrera made his first appearance since March 12, going 1-for-2. He had been out with lower back pain.
GIANTS: Closer Robb Nen pitched one inning in a minor-league game, facing four hitters and using 10 pitches. He pitched to live hitters for the first time since spraining his left ankle March 13.
METS: Catcher Mike Piazza sustained a contusion to the upper left thigh after being hit by a pitch. If Piazza feels okay, he will play today.
REDS: Barry Larkin and Ken Griffey returned to the lineup. Larkin had a single in two at-bats. He hadn't played in nine days because of discomfort in his lower abdomen, where he had a hernia fixed in August. Griffey, who missed two games with a sore knee, struck out, hit into a double play and fouled out.
ROCKIES: Catcher Tony Eusebio was released. His departure leaves Ben Petrick, Gary Bennett and Carlos Hernandez competing for two spots.
