SAN DIEGO - The Padres are mired in misery.
Matt Cain struck out nine in seven innings to win his sixth straight start and Buster Posey, Angel Pagan and Gregor Blanco homered at Petco Park to lead the San Francisco Giants over San Diego 8-3 Thursday.
Former Twins starter Jason Marquis was the losing pitcher as the Padres dropped to 20 games under .500 and the Giants won despite making four errors.
San Francisco scored two runs off three hits and Marquis' throwing error in the first. Posey had an RBI single and Brandon Belt an RBI double.
Posey hit a leadoff shot in the third off Padres newcomer Marquis, driving a 2-0 pitch off the third-floor balcony of the Western Metal Supply Co. brick warehouse in the left-field corner for a 4-0 lead and his seventh homer.
Marquis (0-1) allowed four runs, two earned, on nine hits in six innings. He struck out six and walked one. Marquis was promoted from Double-A San Antonio. He signed a minor league contract on May 29. He started the season with Minnesota.
"I made a few mistakes and I paid for it," Marquis said. "For the most part, I felt good and settled in and got into a rhythm. Toward the third inning I made my pitches when I needed to. Obviously, it was too late by then to get a W."
