CHICAGO -- Geovany Soto was making progress in his rehab at Triple-A Iowa and could join the Cubs as early as Monday. Manager Dale Sveum said the club has talked about keeping three catchers on the roster in Soto, Steve Clevenger and Welington Castillo.
"Clevenger can play different positions on the field, and you're not worried about pinch-hitting," Sveum said. "It opens things up a little bit."
Clevenger, who started on Friday, was batting .281, while Castillo, who was activated from the disabled list on Thursday, was hitting .185. Castillo will start on Saturday.
"We'll see what happens the next day," Sveum said.
In four rehab games with Iowa, Soto was 3-for-12 with two doubles. He's been out since May 17 after undergoing arthroscopic surgery on his left knee.
