Fittingly, the clinching victory came from a Roy Halladay (21-10) shutout — his fourth of the season and ninth complete game, both of which are highs in the majors this season.

He will head to the playoffs for the first time in his 13th major league season, having played his entire career with Toronto before switching teams for this season.

Halladay gave up only two singles, didn't walk a single batter and struck out six. He faced the minimum 21 batters through seven innings, as a third-inning hit was negated when the next batter grounded into a double play.

The Phillies went ahead 1-0 on the first of Jayston Werth's three hits in the game. It was his 26th homer, a drive to left field off John Lannan (8-8) in the second inning. He finished with four RBIs.
 

In Denver, Ted Lilly dominated for eight innings to steer Los Angeles past Colorado.

He gave up one homer, but otherwise bewildered the Rockies. Of Lilly's (9-12) eight strikeouts, five were called.

The reeling Rockies fell five games behind idle San Francisco in the NL West with just six games remaining.

Colorado has lost seven of eight since pulling within a game of the divisional lead on Sept. 18.

Colorado starter Ubaldo Jimenez (19-8) has one more start, at St. Louis next weekend, to try to become the franchise's first 20-game winner. He went 15-1 in the first half of the season but has found victories hard to come by since.
 

In St. Louis, the hosts beat Pittsburgh to stay in the NL Central race for at least one more day.

A Cardinals loss would have clinched the division for Cincinnati. The Reds were idle but can still claim the crown with a win in Tuesday's home game against Houston.

Matt Holliday homered and drove in three runs, tying the game at 4-4 with a two run shot in the sixth.

St. Louis' Dennys Reyes (3-1) picked up the win with one scoreless inning in relief.

Pirates reliever Sean Gallagher (2-1) took the loss.
