Schmidt might miss start with injured groin
"If I tried to go out there and hurt it, it would be the rest of the season," Schmidt told the paper. "It could be part of the offseason, too."
The third baseman went on the DL on Aug. 26 with a hairline fracture of his right middle finger. He was hit by Jesse Crain's pitch in a game against the Twins on Aug. 25.
Crede entered the game with a .232 average and 16 homers and 48 RBI. His .973 fielding percentage is second-best in the American League.
He had been taking batting and fielding practice the past few days.
"I think it's time for us to see what he's got," White Sox manager Ozzie Guillen said. "To see if he is going to help us in the stretch. That's the biggest issue. When the swing's ready, I have to put him in there to see how he's going to go."
Gavin Floyd will take Padilla's turn in the rotation on Tuesday against NL-leading Atlanta. The Phillies entered Saturday night's game against Florida 1½games behind Houston in the wild-card race.
Padilla allowed five runs and seven hits in 5 1/3 innings against the Astros on Wednesday. It was one of his poorest outings since the All-Star break. Since nearly being pulled from the rotation and almost losing his roster spot after starting 3-8 with a 6.69 ERA, Padilla was 5-4 with a 2.60 ERA in his previous 11 starts.
Overall, Padilla is 8-12 with a 4.67 ERA in 24 starts this season. Floyd, a former first-round pick, is 1-2 with an 11.25 ERA in five games, including three starts.
