Zambrano is 0-1 in three Opening Day starts, losing last year to Cincinnati. At the Cubs' winter fan fest in January, he said Ted Lilly could start the season opener March 31 against Milwaukee.
"What I said at the convention, I was just playing," Zambrano said Thursday. "I'm going to be out there the first day and try to win the first game. The one who invented the light tried 2,000 something times, and finally he did it. We have light. I don't want to spend 2,000 times to win the first game on Opening Day, but I think I will do it this year and go from there."
