Zito rocked early in Giants' loss

HOUSTON -- Brett Myers pitched seven effective innings, Jeff Keppinger had three RBIs and the Houston Astros beat the San Francisco Giants 6-3 on Wednesday night to snap a five-game losing streak. Myers (5-5) allowed three runs, one earned, and six hits, becoming the first player in franchise history to begin the season by pitching six innings or more in each of his first 15 starts. He also had two hits and drove in a run. It was the shortest outing of the year for Giants starter Barry Zito (7-4), who yielded five runs and seven hits in four innings. Carlos Lee hit an RBI single in the first and Keppinger added a three-run double in the second to help Houston build a 4-0 lead. Matt Lindstrom pitched a perfect ninth for his 16th save as the Astros ended a seven-game skid against the Giants this season. The Giants rallied in the fifth, taking advantage of a pair of errors by Astros third baseman Chris Johnson. Aaron Rowand reached second on Johnson's one-out miscue and Andres Torres followed with a triple to right field. Freddy Sanchez got on base when Johnson made another mistake, this time on a bad throw to first base. Torres scored on Aubrey Huff's infield out and Pat Burrell walked to load the bases, but Myers got Pablo Sandoval to fly out, preserving Houston's 5-2 lead. Myers hit an RBI single in the fourth and Johnson's run-scoring double in the sixth made it 6-2. Juan Uribe added an RBI double in the seventh for San Francisco. NOTES: Houston ace Roy Oswalt hasn't heard anything about a possible trade since asking to be dealt last month. He told his agent not to come to him unless "there's something on the table." So far that hasn't happened. The 32-year-old expects to hear more about his future after the All-Star break, when teams are looking ahead to the second half of the season. ... Astros SS Tommy Manzella has a broken index finger and will be out about six weeks. ... San Francisco's Joe Martinez, who is scheduled to start Saturday against Boston, walked one in a scoreless seventh inning.
