PHOENIX – Jason Kubel hit a two-run homer and five relievers filled in for scratched starter Joe Saunders to lift the Arizona Diamondback to a 6-1 win over the Cubs on Friday night.

Saunders had trouble getting loose in the bullpen, so the Diamondbacks turned to one-time starter Josh Collmenter. He gave up a long homer to Geovany Soto in the fourth and Brad Ziegler (4-1) followed with two scoreless innings.

David Hernandez escaped a bases-loaded jam in the eighth and pitched a perfect ninth to finish off his second save and Arizona's eighth victory in nine home games.
