Doc got the best of The Freak this time in a rematch of aces.

Roy Halladay pitched through a groin pull, outdueling Tim Lincecum and keeping the Philadelphia Phillies alive in the NL championship series with a 4-2 victory over the San Francisco Giants in the NL championship series Thursday night.

Jayson 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 and forced a Game 6 back home in Citizens Bank Park on Saturday.

Halladay improved to 2-1 with a 2.45 ERA in three postseason starts this year, doing it with a groin pull suffered in the second inning.

Philadelphia put San Francisco's celebration on hold, taking this matchup of Cy Young Award winners after Lincecum came out on top in the opener.

The Giants now must win once in two tries on the road for the franchise's fourth pennant since moving West in 1958.
