Polanco drove in three runs with two singles and a triple, and raised his average to .379. Andy Benes allowed three runs in seven innings to get the win, improving to 4-2. The Cards took two out of three from Pittsburgh, and have regained sole possession of first place, by one game over Cincinnati. The Cards are off today and host the Marlins Tuesday.
