Arizona 6, Chi. Cubs 1

Diamondbacks 6, Cubs 1: Jason Kubel homered and Arizona overcame a last-minute pitching scratch for a home win against lowly Chicago.

After Geovany Soto’s solo home run in the top of the fourth gave the Cubs a 1-0 lead, Kubel answered with a two-run shot in the bottom of the inning against Jeff Samardzija (5-6), putting the Diamondbacks in front to stay. Aaron Hill added an RBI single in the fifth, and Miguel Montero’s two-run triple in the sixth made it a four-run game.

Arizona’s scheduled starter, Joe Saunders, was scratched just before the game because he was unable get loose during his warmup. His fill-in, Josh Collmenter, gave up just three hits in four innings, walking three and striking out six. Brad Ziegler (4-1) got the win after pitching the fifth and sixth innings.

Justin Upton closed out the scoring in the seventh inning, driving home a run with a ground-rule double off Chicago reliever Jairo Asencio.

The Cubs, who stranded 11 men, loaded the bases in the second and eighth innings but failed to score in both instances.
