Dontrelle Willis picked up his 7th win of the season, pitching eight innings, giving up just one run, beating Roy Oswalt and the Astros in a pitcher's duel. ``These games are key,'' Willis said. ``People put so much emphasis on September and August, but these games are key because we have to play well now to get to those key situations in September.'' The Marlins scored both their runs when Damion Easley hit an inside the park home run.
