Pettitte, Duke (MLB.com)
Andy Pettitte (11-13, 4.51) vs. Zach Duke (8-11, 4.94).
Like Van Slyke says, one of the important factors behind Duke's recent streak of good pitching is that he isn't walking anyone anymore. In every month so far this year, he's walked at least ten batters; Saturday's game will be his last one in August, but he's only walked four batters in August so far. In his last six starts, he's allowed more than one walk only once. He still isn't striking anyone out, but if he keeps the free passes to a minimum, he can continue to have at least modest success.
