Roy Halladay outdueled Tim Lincecum and kept the Phillies alive in the NL championship series, pitching them back home for another attempt to stave off elimination with a 4-2 victory over the San Francisco Giants on Thursday night.
Werth's solo homer in the ninth quieted the raucous sellout crowd of 43,713, and many fans began making for the exits even before Philadelphia pulled within 3-2 in the best-of-seven series.
Halladay's bunt -- which appeared to foul -- helped spark a three-run third inning, when Shane Victorino drove in the first of two runs that scored on a fielding error by first baseman Aubrey Huff.
Placido Polanco followed with an RBI single, and the two-time reigning NL champions forced a Game 6 back home in Citizens Bank Park on Saturday and another cross-country trip.
Jonathan Sanchez starts for the Giants against Roy Oswalt, who is 10-0 in 12 starts at Philadelphia this year.
