The San Francisco Giants look to avoid matching their longest losing streak in four years when they visit the Arizona Diamondbacks on Saturday in the second of a three-game series. The Giants have dropped six in a row and nine of their last 10 games, prompting manager Bruce Bochy to hold a team meeting following Friday's 4-1 setback. "I like to look at the 60 games where we played great baseball, as to who we are, not the last 10 games," Bochy said.San Francisco, which still leads the National League West by four games, hasn't lost seven in a row since June 26-July 2, 2010 - a year that culminated in a World Series championship. Second baseman Aaron Hill, who broke out of an 0-for-12 funk with two hits and two RBIs in Friday's win, is 9-for-19 against Giants right-hander Ryan Vogelsong, who will opponse Arizona's Brandon McCarthy. The Diamondbacks have won only three of their last 10 games.TV: 10:10 p.m. ET, CSN Bay Area (San Francisco), FSN Arizona PITCHING MATCHUP: Giants RH Ryan Vogelsong (4-3, 3.94 ERA) vs. Diamondbacks RH Brandon McCarthy (1-9, 5.18)Vogelsong failed to go past five innings for the first time in 10 starts last time out, giving up three runs and seven hits while not factoring in the decision versus Colorado.
