Philadelphia captured the National League Championship Series in five games and earned a week off before the World Series begins Oct. 28.
After winning one World Series title in the franchise's first 124 years, the Phillies will now try for two in a row. They defeated Tampa Bay to win the championship last year, adding that crown to the one they claimed in 1980.
Werth quickly rallied Philadelphia from a 1-0 deficit with a three-run homer in the first inning. Pedro Feliz hit a solo shot in the second, Shane Victorino had a two-run blast in the sixth and Werth tacked on a solo home run in the seventh. Werth hit 36 homers in the regular season and has five in the playoffs.
The Phillies scored their 10 runs on just eight hits. Two of the three runs Philadelphia produced without homers came on wild pitches.
Despite the one-sided victory, Philadelphia starter Cole Hamels failed to last long enough to get the win. Hamels, who had a 4-0 record in last year's playoffs, has just one post-season victory thus far in 2009.
With the Phillies owning a 6-3 lead in the fifth and a runner on second with one away, Hamels was replaced by J.A. Happ. Ronnie Belliard drew a walk off Happ, who then got Andre Ethier to fly out to left.
That brought up Manny Rodriguez as the potential tying run and Chad Durbin was summoned to face the Los Angeles slugger. On the fifth pitch of the at bat, Ramirez grounded back to Durbin, ending the inning and effectively ending the season for the Dodgers.
