Perez, exiled to Triple-A Portland after a dismal April, will take the mound for the finale of a three-game series with the Chicago White Sox at U.S. Cellular Field.
Perez went 4-5 with a 3.50 ERA in 16 appearances, including 15 starts, as a rookie in 2002. But he was 1-3 with an 8.23 ERA in six April starts before his demotion.
After going 3-3 with a 3.02 ERA in eight outings with Portland, Perez earned a promotion, taking the roster spot of right-hander Brian Tollberg, who was optioned down. The 21-year-old left-hander from Mexico is anxious to prove himself.
“This is like starting over,” he said. “I want to come in like last year when I came up. I was working hard down there, waiting for the call. Its good to be back here, I want to work hard to stay here.”
The Padres, who are 8-25 on the road this season, dropped their second straight in Chicago on Saturday as Frank Thomas belted a two-run homer to lift the White Sox to a 6-5 win.
Thomas is 22-for-57 with seven homers and 17 RBIs in 16 games since being moved to first base from the designated hitter’s slot. The former two-time AL MVP has raised his average from .250 to .284 since going back to his natural position.
The White Sox have won five of seven since opening June 1-6.
STANDINGS (through June 13): Padres - 5th place, 22 GB, NL West. White Sox - 3rd place, 8 1/2 GB, AL Central.
PADRES PROBABLE STARTER: Perez (1-3, 8.23 ERA). Perez is 3-4 with a 4.64 ERA in 11 career road starts.
WHITE SOX PROBABLE STARTER: Jon Garland (4-5, 5.29 ERA). Garland allowed two run and five hits over seven strong innings in Tuesday’s 5-3 win at San Francisco, rebounding nicely from his worst outing of the season. The right-hander was pounded for season highs of seven runs and 10 hits in a 8-6 loss at Arizona on June 4. Garland, who has yielded two runs or fewer in four of his last five starts, is making his first career appearance against the Padres.
