SAN DIEGO -- Arizona's Brandon McCarthy went seven innings and won for just the second time this season, pitching the Diamondbacks past the Padres 2-1 on Friday night.
McCarthy (2-10) limited San Diego to one run and six hits. He struck out seven with no walks as he beat the Padres for the second time this season and fourth in five career decisions.
Addison Reed pitched the ninth inning for his 18th save in 21 chances.
The Padres, who were no-hit by the Tim Lincecum of the San Francisco Giants in their last game, were again challenged offensively.
Tyson Ross (6-8) took the loss as the Padres continued a disturbing trend. In Ross' last five starts the Padres have scored one run.
The Padres cut Arizona's lead in half in the fifth inning on a sacrifice fly by Ross. He drove in Cameron Maybin who reached on a single and took third on a single by Alexi Amarista.
San Diego squandered a chance to tie the game in the sixth when Chase Headley reached third with one out. But with the infield in, Will Venable grounded to Aaron Hill at second base and he erased Headley trying to score. Venable was retired when he broke for second base while Headley was in a rundown.
The Diamondbacks broke the scoreless tie in the fourth when Paul Goldschmidt walked to open the inning, which preceded a single by Miguel Montero. They advanced to second and third on a wild pitch by Ross.
David Peralta drove them both in with a sharp one-out single up the middle. Martin Prado smacked a similar ball toward centre, but with Amarista covering second on a steal attempt by Peralta, he was in position to turn an inning-ending double play.
Down 2-0, the Padres had an opportunity to cut into their deficit when Headley and Yasmani Grandal had consecutive one-out singles in the fourth inning. But Venable and Jake Goebbert struck out looking to squash the rally.
The Padres got their first hit in 11 innings in the third when Ross bunted for a two-out single. Ross' effort down the first base line was fielded by McCarthy but his throw was late and offline.
Ross, the Padres' second base runner over that 11-inning span, didn't go far. Everth Cabrera followed with a ground ball to shortstop to end the inning.
