Cubs cautious with Carlos Zambrano

MESA, Ariz. -- Chicago Cubs manager Mike Quade is taking a cautious approach with the sore left wrist of Carlos Zambrano and will use a designated hitter during the pitcher's fifth start of the spring on Friday.

With a home game against the Cincinnati Reds, the Cubs would typically bat the pitcher. But Quade opted to protect Zambrano from having to swing a bat by using a DH.

Zambrano has had his left wrist wrapped the past two days in the locker room prior to practice.

"I don't know," Quade said when asked what was wrong with Zambrano's wrist. "I can see the same thing you do. Guys wrap their arms and their shoulders. I don't pay much attention to that. The only thing I want the guy to do is pitch. But guess what? If I see where we can err on the side of caution, that's what we will do."

Zambrano ended last season by winning eight of his final 10 starts, and has impressed this spring with a 1.38 ERA, allowing two earned runs in 13 innings going into Friday's start.
