Pittsburgh right fielder Xavier Nady accidentally knocked Adam Dunn's fly ball over the wall for a two-run homer in the first inning Saturday, then stood with his hands on his hips in disbelief over his gaffe. Dunn's high fly got caught in the swirling wind and drove Nady within a step of the green-padded wall. Nady reached for the ball, which smacked the middle of his glove and then deflected into the first row of seats, hitting a gray-coated man wearing a Reds cap.
