Felix Diaz, who has lost two of his three starts, is in the mix for now, but it will be up to Scott Schoeneweis to see how the White Sox's rotation shapes up after the All-Star break.
Diaz yielded three runs on two home runs in Saturday's first inning, then settled down and gave up only three singles in the next three innings before being lifted for a pinch-hitter. Diaz also struck out a career-high six batters in the Cubs' rain-shortened 4-2 victory.
"Diaz threw the ball real, real good," Sox manager Ozzie Guillen said. "He only had one bad inning, a couple of bad pitches. But the way that kid came back and finished up the game, he showed me something."
Diaz gave up a leadoff triple to Todd Walker. Then Rey Ordonez hit a two-run home run. After he retired Sammy Sosa on a popup, Moises Alou hit a solo home run.
"The pitch I would take back is the one to Alou," catcher Sandy Alomar Jr. said. "We tried to come back with a slider, but the ball stayed middle in and he was all over that."
Guillen said he wasn't sure how he would use Diaz in the final week before the All-Star break. Schoeneweis is scheduled to come off the disabled list Wednesday and pitch against the Anaheim Angels. If Schoeneweis pitches well, it creates an interesting dilemma for Guillen.
"That's a good problem to have," Guillen said. "If Schoeneweis pitches the game he's supposed to pitch and helps us there, he's my No. 5 man because he was there before and Diaz maybe goes to the bullpen."
Willie Harris made his third start since June 22 at second base, going 1-for-3 and scoring the first Sox run after a sixth-inning single. "Willie was his own worst enemy," Guillen said. "He played well one day and then all of a sudden he doesn't have any confidence when he goes 0-for-4. But when you play every day in the big leagues, you're going to have 0-for-4 a lot."
Juan Uribe was out of Saturday's starting lineup after starting 39 of the previous 40 games. Uribe's average has fallen to .285 after a 6-for-46 (.130) span, dipping below .300 for the first time since April 13.
Frank Thomas struck out pinch-hitting for Diaz, the second time he has struck out as a pinch-hitter in the series. Thomas is 0-for-3 as a pinch-hitter this season and 4-for-23 in his career.
Guillen said the Sox will keep Jon Rauch and use him in the bullpen for a while.
