SAN FRANCISCO -- The start of the Los Angeles Dodgers' biggest series of the season, at least until the next one, couldn't have gone much worse.The team's third-best starting pitcher, Hyun-Jin Ryu, left Friday night's game with a shoulder injury after pitching a first inning during which the San Francisco Giants batted around en route to a 9-0 win at AT&T Park.The Giants are coming hard, having won 10 straight home games, and they narrowed the Dodgers' NL West lead to just one game, the narrowest it has been since July 26.
