Ryan Vogelsong picked up where Barry Zito left off and the San Francisco Giants had the Los Angeles Dodgers once again searching for answers and runs. Vogelsong pitched seven innings to outduel San Francisco nemesis Clayton Kershaw for the second time this season and Melky Cabrera homered to help the Giants move within a game of Los Angeles for first place in the NL West with a 2-0 victory Tuesday night. Vogelsong (7-3) followed Zito's seven innings in Monday's 8-0 win in the series opener with his own gem, marking the first time the Dodgers had been blanked in consecutive games in San Francisco since 1987 and for the second time ever.
