PHOENIX (AP) -- Ian Kennedy pitched eight dominant innings to become the NL's first 20-game winner, Justin Upton hit a broken-bat homer and the Arizona Diamondbacks moved a step closer to their first NL West title in four years with a 1-0 win victory the Pittsburgh Pirates on Monday night.

Kennedy (20-4) allowed one hit, walked one and tied his career high with 12 strikeouts to become the fourth Diamondbacks pitcher to reach 20 wins.

Upton led off the sixth with his 31st homer off Jeff Karstens (9-9), snapping off his bat on a shot to left that was upheld by a video review.

J.J. Putz stranded Alex Presley at third to close out the two-hitter with his 42nd save, dropping Arizona's magic number to four over idle San Francisco.
