Cubs starting pitcher Carlos Zambrano could miss his next scheduled start after straining his hamstring during Sunday's win over the Marlins. Zambrano suffered the injury while successfully beating out a bunt attempt in the fifth inning. "I would say right now that's in jeopardy, and if I had to guess, I'd say no," manager Lou Piniella said of Zambrano making his next start. Zambrano will have an MRI on the hamstring.
