Giants slugger Gregor Blanco hit a go-ahead triple to lead San Francisco over the Detroit Tigers 2-0 on Saturday and into a 3-0 World Series lead.
Pitcher Ryan Vogelsong escaped trouble three times as the Giants moved one win from their second title in three seasons and became the first team to toss consecutive shutouts in the Series since Baltimore ended 1966 with three straight against the Los Angeles Dodgers.
Vogelsong became only the third pitcher to make four straight starts in a single postseason in which he allowed no more than one run, giving up five hits in 5 2-3 innings with four walks and three strikeouts.
