SAN FRANCISCO -- Rene Rivera remembers his last home run, three years ago next month at Oakland for the Minnesota Twins. His latest will certainly be memorable, too, and did plenty to give San Diegos inconsistent offence a boost. Rivera hit a go-ahead three-run homer in the fifth to follow his two-run double for a career-high five RBIs, single handedly backing Tyson Ross in the Padres 6-4 victory against the San Francisco Giants on Monday night. "Sooner or later our hittings going to come around," Rivera said. "We needed this one. Its a good feeling. Its good for the team." Ross (3-3) did just enough over 5 1-3 innings to beat the Giants for the second time in 11 days, allowing eight hits and four runs with four strikeouts and two walks. After Michael Morse put San Francisco ahead on two-run single in the fourth, Rivera answered with his first homer of the year. He hadnt driven in a run all season before Monday, and the five RBIs were most by a Padres player at 15-year-old AT&T Park. "We needed a game like that from one of our guys," manager Bud Black said. "Its been a long time coming. Weve had a hard time scoring runs in bunches." Brandon Hicks homered for the second straight day, following his walkoff a day earlier against Cleveland with a leadoff shot in the fifth. Hunter Pence hit an RBI triple in the fourth. First base umpire Angel Hernandez had two calls overturned by replay. Giants manager Bruce Bochy came out in the third to request a review after Hernandez called Xavier Nady safe on a close play at first. The umpiring crew overturned the call in 1 minute, 31 seconds. Hernandez was involved in another overturn in the fourth when Black requested a review. Ross was ruled thrown out by third baseman Pablo Sandoval. In 1:18, the call was overturned and Sandoval was charged with an error. Giants starter Madison Bumgarner (2-3) walked a season-high four, and his four earned runs matched his most of 2014. He didnt pitch into the sixth for the third time in his six starts and lost three straight outings for the first time since Aug. 25-Sept. 5, 2012. The Giants had won seven straight home games against the Padres started by the lefty. "I think its fair to say hes made a few more mistakes than were accustomed to," Bochy said. "A strange night. We just couldnt get it done." Ross, born in Berkeley and raised in Oakland, faced the minimum through three -- helped by double plays in the first and second then two strikeouts in the third. The right-hander pitched eight scoreless innings with nine strikeouts in his April 18 win against San Francisco at Petco Park as San Diego took two of three from its division rival. "Its always nice to come back home and get a win," Ross said. "The defence was great tonight and got me out of a couple jams, and the offence came to play." Alexi Amarista drove in an insurance run in the top of the ninth. Huston Street, San Diegos fourth reliever, then finished for his 10th save in as many tries and 35 of 36 dating to last May. He lowered his ERA to 0.82. NOTES: A moment of silence and a video tribute were held before the game for Hall of Fame Padres broadcaster Jerry Coleman, who died in January at 89.
