CHICAGO -- Cubs catcher Geovany Soto was not available to play in Saturday's 4-3 loss to the Reds because of a mild ligament sprain in his right shoulder.
Soto's shoulder bothers him when he's hitting, not throwing. He was not expected back in the Cubs' lineup until Monday at the earliest.
"We were down to one catcher, Soto wasn't available," Cubs manager Lou Piniella said. "We couldn't even pinch-run for our catcher when we bunted. We had chances in the ninth with the middle part of the lineup and didn't get it done."
Koyie Hill caught Saturday and will be behind the plate Sunday as well.
