Cardinals standout starter Michael Wacha doesn't generally require much run support to win. But what the heck - his offense gave him plenty anyway Saturday against the Cubs.

The game started out taut, but St. Louis scored four in the fourth and four more in the fifth to allow Wacha to cruise to his 10th victory, which is tied for second in the majors.

The onslaught allowed Wacha to depart after six inning and 91 pitches. He allowed one run on six hits with two walks and five strikeouts. He actually fell behind 1-0 on an RBI single by opposing pitcher Donn Roach in the second inning.

The fine outing continued a period of inconsistency for Wacha, who has traded excellent outings with mediocre ones over the past month.
