OAKLAND Petalumas Jonny Gomes snapped an 0-for-34 slump as a pinch-hitter with a go-ahead two-run homer in the seventh inning as the As beat the San Diego Padres 6-4 to up their season-long win streak to five games.Starting pitching report: Tyson Ross allowed no hits through five innings and was briefly in line for his third win of the season with six solid innings in his first big-league start since May 30.Manager Bob Melvin said before Saturdays game that he wanted to see improvement on Ross secondary pitches. Ross was perfect in the first inning, striking out both Everth Cabrera and Chase Headley on sliders.Ross wasnt as sharp in the second inning, hitting Carlos Quentin with a pitch to put the leadoff man on. Quentin advanced to second on a wild pitch and catcher Kurt Suzuki bailed Ross out on two other pitches way outside the strike zone. But Ross recovered to escape unscathed as he worked a fly out from Mark Kotsay and groundouts from Yonder Alonso and Cameron Maybin.The third inning was an enigma for Ross, as he went first-pitch fly out, walk, first-pitch fly out, walk to start the frame. Headley swung at another slider for a strikeout, though, to get Ross out of the self-inflicted jam.Ross issued his third walk of the game with one out in the fourth, but erased it with a strike em out, throw em out double play. Alonso swung through a slider for Ross fourth strikeout of the afternoon and Suzuki gunned down Kotsay to end the inning. Suzuki allowed steals on 16 consecutive attempts this season, but has since tossed out six of the last nine would-be thieves.Three straight fly balls to the outfield helped Ross cruise through the fifth, but his no-hitter and shutout bid both came to an end in the sixth. After back-to-back strikeouts, Ross issued his fourth walk to Headley, who came around to score on Quentins fifth home run, a shot that barely cleared the yellow line above the out-of-town scoreboard in left.Ross completed the inning, but was replaced by Sean Doolittle to start the seventh with the As leading 3-2.His final line: 6 IP, 1 H, 2 ER, 4 BB, 6 K.Bullpen report: Doolittle, who entered the game having struck out 10 of the 19 batters he faced since his call up on June 4, gave up a double to Alonso to lead off the seventh. He then went strikeout, walk, strikeout, before giving up a bases-clearing double to Will Venable for a 4-3 Padres lead. Both hits in the inning off the southpaw Doolittle were from left-handed batters.One-time closer Grant Balfour got the call in the eighth and soon had runners on the corners. He issued a one-out walk to Quentin, who hustled to third on a single by Kotsay, but got out of the jam when Allen snagged a sharp line drive off the bat of Alonso and doubled up Kotsay at first.New closer Ryan Cook came in for his fourth opportunity of the season and snagged a sharp comebacker from Cameron Maybin and threw to first for a quick out to start the ninth. Cook sruck out John Baker looking and and Jesus Guzman swinging for his third save.At the plate: After scoring at least eight runs in their last four games, the As had a more pedestrian day at the plate on Saturday, finishing with six runs on eight hits.No Athletic reached base until No. 9 hitter Cliff Pennington worked a two-out walk off Padres starter Ross Ohlendorf in the third inning. Pennington promptly stole second, and then watched as Ohlendorf issued a free pass to Coco Crisp. With a chance to drive in the games first run, Weeks worked a 3-2 count to put the runners in motion, but hit a weak fly ball to left to end the threat.The As broke through against Ohlendorf in the fourth inning, as Seth Smith hit home run No. 7, all of which have come as an outfielder instead of as a designated hitter, for a 1-0 lead. Oakland added another run as Colin Cowgill singled to left to drive in Brandon Moss, who had doubled high off the right-field wall to start a two-out rally.Ohlendorf was knocked out of the game in the fifth inning as the As took a 3-0 lead thanks to Pennington and Weeks. The former led off the inning with a single and the latter drove him in with a double to right-center field. Josh Reddicks deep fly ball to right-center allowed Weeks to tag up and advance to third. Padres manager Bud Black then took the ball from Ohlendorf and turned it over to Alex Hinshaw, who drilled Smith before striking out Brandon Inge looking to end the inning.The As went down in order in the sixth, but put together another rally in the seventh. With runners on the corners and lefty Joe Thatcher on the mound, Melvin pinch-hit right-hander Jonny Gomes for the left-hander Smith. After Thatcher fell behind Gomes 1-0, Black made a mid at-bat pitching change, turning to right-hander Luke Gregerson. Blacks move didnt pay off, as Gregerson bounced the first pitch he threw in the dirt, allowing Pennington to score from third standing up to tie the game. Gomes broke the tie quickly, launching a 3-1 fastball from Gregerson deep into the left-field seats. The two-run homer snapped an 0-for-34 streak as a pinch-hitter for the veteran from Petaluma.Weeks and Cowgill finished with two hits apiece, while Crisp, Reddick, Inge and Suzuki were all hitless.
