"Alfonso Soriano will miss some time with a left quad strain he suffered while running to first base in the first inning of Monday's 12-7 loss to the Astros.

Soriano had an MRI on the quad, but there was no word on whether he'd go on the 15-day disabled list. If so, Tyler Colvin and Brett Jackson are available for call-ups, though manager Mike Quade said he'd leave Blake DeWitt in left for now.

DeWitt went 3-for-4 Monday after replacing Soriano, and has made one start in left field. Quade said the Cubs needed DeWitt's bat in the lineup.

"It's unfortunate to see Sori go down like that," DeWitt said. "He's a big part of this team, and it was a tough loss today."

DeWitt lost his footing on one play that led to a run, but also threw out a runner at the plate.

Lopez watch: Rodrigo Lopez allowed six runs on 10 hits over 42/3 innings in his Cubs debut, blowing a three-run lead."
