Arizona Diamondbacks starting pitcher Patrick Corbin pitches against the San Diego Padres in the first inning of a baseball game in San Diego, Saturday, May 4, 2013.

SAN DIEGO (AP) — Patrick Corbin pitched seven solid innings and the Arizona Diamondbacks snapped their season-high four-game losing streak with an 8-1 victory over the San Diego Padres on Saturday night.

Corbin (4-0) gave up one run and five hits while striking out seven. He walked three while his ERA dropped to 1.80. Corbin has opened the season by pitching at least six innings and allowing two runs or less runs in his six starts — all Arizona victories.

He lost his shutout bid with two out in the seventh when Chris Denorfia hit his second homer into the second deck in left field. Denorfia also had a double. The D-Backs touched up Padres starter Clayton Richard (0-4) for six runs on five hits in the second.

Richard had never lost to the Diamondbacks going 6-0. He left in the fourth after giving up seven runs.
