Cantu hits 3-run homer, sends Padres past Arizona

Jorge Cantu hit a three-run homer and Aaron Harang pitched seven solid innings to lead the San Diego Padres to a 4-3 win over the Arizona Diamondbacks on Sunday.

Padres center fielder Cameron Maybin helped preserve a late lead with a catch on Xavier Nady's long sacrifice fly in the eighth inning.

Cantu, hitting .184 coming into the game, homered in the first to cap a four-run burst.

The Padres, who were shut out for a major league-high eighth time Saturday night, came out swinging against Joe Saunders (0-4). It was San Diego's biggest first inning since scoring five times against Harang on July 29, 2009, at Cincinnati.

Going into this game, the Padres had scored a total of five runs in the first inning this season.

Harang (5-2), who lost his last two starts, was efficient against Arizona. The right-hander gave up two runs as he scattered eight hits. But he walked just one and got two double-play grounders.

The Diamondbacks closed to 4-3 in the eighth on Nady's sacrifice fly, but it could have been worse for the Padres.

Justin Upton reached on a one-out single off Mike Adams and went to third on Miguel Montero's single. Nady followed with a drive to the gap and Maybin made the catch as he fell to the warning track. Adams struck out Melvin Mora to end the inning.

Heath Bell pitched the ninth inning for his eighth save in nine chances. Bell's streak of 41 consecutive saves was snapped on Friday night when he blew a 3-0 lead in the ninth, the final two scoring on Chase Headley's two-out throwing error.

Harang pitched into the seventh inning for the first time this season. Harang went six innings apiece when he set the franchise record by winning his first four starts. He also had an ERA of 1.88 in those starts.

But Harang was hit hard as he allowed 12 earned runs in his last two outings, including a career-high tying eight in a 8-2 loss April 26 against Atlanta.

San Diego has won 11 times in 13 games against the Diamondbacks at Petco Park since 2009.

Chris Denorfia led off the Padres first with a single and scored on Jason Bartlett's double. After Headley drew a one-out walk, Cantu hit a 1-2 pitch from Saunders into the left-field seats for his third homer. The home run was just the 21st for the Padres, second-lowest total in the NL.

Arizona's only big threat against Harang came in the second after Josh Wilson doubled in Mora with two outs. Saunders followed with an RBI single, the first of his two hits. But Harang got out of the inning when Chris Young lined out.
