SAN DIEGO -- Ian Kennedy's solid pitching and offensive production throughout the San Diego Padres lineup was enough to beat the Arizona Diamondbacks 12-2 on Wednesday night.
Kennedy (7-10) struck out seven and allowed two runs and six hits in seven innings while facing his ex-team for the second time since being acquired by the Padres on July 31. He had a no-decision in their previous encounter.
The Padres hit three homers, four batters had at least two RBIs and four batters finished with multiple hits.
Jedd Gyorko continued his solid season, as his 21st home run placed him one ahead of the Atlanta Braves' Evan Gattis for the major league lead among rookies. Chase Headley had three RBIs, with Gyorko and Chris Denorfia getting two each.
Gyorko's two-run homer capped a four-run fifth that gave the Padres a 6-2 lead. Denorfia accounted for the other runs with a two-run single which scored Kennedy and Will Venable.
For Arizona starter Randall Delgado (5-7) that was his last inning after surrendering six runs and seven hits.
The Padres' Tommy Medica homered in the fourth to tie the score 2-2. It was Medica's third homer since being elevated from Double-A on Sept. 10.
Medica's blast erased Kennedy's mistake in the top of that inning, one that came without him delivering a pitch.
Paul Goldschmidt opened with a double and advanced to third on Martin Prado's single. With runners at the corners, Kennedy stepped toward third on a pick-off attempt, but didn't throw the ball. Goldschmidt scored on the balk for a 2-1 lead.
The Diamondbacks had pulled even at 1 in the third when Delgado drove in Gerardo Parra with a single up the middle. Parra led off the inning with a double after Kennedy retired the first six batters.
Two doubles got the Padres a run in the first. Headley's double off Parra's glove in right-centre chased home Denorfia, who was aboard after his one-out double.
Chris Robinson's three-run homer in the eighth was the first hit of his career, coming on his sixth major league at-bat.
Rene Rivera, Headley and Denorfia all had three hits for the Padres.
