San Francisco @ San Diego preview

Last Meeting ( Aug 17, 2012 ) San Francisco 10, San Diego 1

The Giants were shaken by Melky Cabrera's 50-game suspension for using a banned substance, but they still know how to beat the Padres. San Francisco has won 18 of the last 24 meetings with San Diego, including Friday’s 10-1 rout. Playing its second game since Cabrera’s suspension was announced, the Giants moved one half-game ahead of the Dodgers in the National League West. The Padres have lost four straight while being outscored 28-2, and they'll be looking for a long outing from Eric Stults on Saturday after using six pitchers in the series opener.

With Cabrera out, the Giants are giving Gregor Blanco regular playing time in left field. General manager Brian Sabean has indicated the team is satisfied with Blanco, who broke out of an 0-for-21 slump by going 4-for-8 in his last two games. Hitting behind Blanco in the bottom of the order, shortstop Brandon Crawford is batting 13-for-31 (.419) during his career-high nine-game hitting streak. The news is considerably worse in San Diego, which learned Friday that starting pitcher Tim Stauffer is out for the rest of the season with a sore shoulder and a flexor tendon issue in his elbow. Stauffer made just one start with the Padres this season.
