The big question on Big Z

The Cubs may have a difficult decision to make after the 2010 season.

Carlos Zambrano’s sudden resurgence has created a great debate.

Keep Zambrano, who had another stellar start in leading the Cubs past Milwaukee 4-0 on Friday, and the $36 million still owed to him over the next two years or trade him at a relative peak and free up some new money to go after free agent pitchers like Texas’ Cliff Lee this coming offseason.

Zambrano is now 5-0 since returning from the restricted list on Aug. 9. He missed five weeks with a negotiated deal that had the volatile Cubs pitcher attending anger-management therapy, which he’ll continue to do for another six months.

After throwing 8 2/3 innings of three-hit, shutout ball against Milwaukee, Zambrano was asked about the possibility of being traded in the offseason.

“I don’t want to talk about that,” he said. “I feel happy, I love this team and I want to stay here. I want to stay here the rest of my contract. No more trade talk.”

Zambrano has complete no-trade clause in his deal, which originally was for $91 million. After the game, the new Zambrano was cool, calm and collected.

Manager Mike Quade replaced him after Starlin Castro’s two out error in the 9th inning, preventing Zambrano’s chance of throwing his first shutout since Sept. 25, 2009.

“I said the other day, sometimes I get frustrated when someone commits an error,” Zambrano said.

At the end of the day, you realize we’re human and you realize we all make a mistake.”

Certainly that quote seems more likely to come from Gandhi than the newly-focused, newly-improved Carlos Zambrano.
