Cubs catcher Geovany Soto was scheduled to play back-to-back games for nine innings each Saturday and Sunday for Triple-A Iowa in Des Moines as part of his rehab before being activated from the disabled list. However, Soto was scratched from Saturday's lineup because of a wet field.
Soto has been sidelined since May 17 after undergoing arthroscopic surgery on his left knee to repair a torn meniscus.
Third baseman Ian Stewart, on the disabled list with soreness in his left wrist, will see a specialist Monday at the Cleveland Clinic. Stewart was batting .201 in 55 games this season.
Sveum said he's talked to Starlin Castro about whether or not the shortstop wants a day off. Castro has played in all of the Cubs' games this season, but this month was 12-for-59 (.203).
"He's such a huge asset on the field every day," Sveum said. "It's just hard when you're not winning a lot of ballgames to take one of your best players out of the lineup."
