The improvement continued until 2007, when the Rockies' 4.32 team ERA was eighth best in the league. Coupled with an offense that produced the league's best batting average and the second most runs scored, the Rockies reached the post season for the first time since 1995. Rockies pitching allowed just eight runs and held the Philadelphia Phillies to a .172 batting average to sweep the 2007 National League Division Series in three games. Likewise, they held the Arizona Diamondbacks to just eight runs in their four-game sweep of the 2007 National League Championship Series to head to the World Series for the first time in franchise history.
