PHILADELPHIA -- The Phillies locked up home-field advantage in the National League Division Series on Saturday, but they lost an opportunity for home field in the NL Championship Series.

The Milwaukee Brewers beat the St. Louis Cardinals at Busch Stadium on Saturday to guarantee the Phillies the second-best record amongst NL division winners. Philadelphia is 92-69 and St. Louis is 91-70, but even if the Phils lose and the Cards win Sunday to both finish 92-70, the Phillies win the tiebreaker against the Redbirds because they went 4-1 against them this season.

But because the Phillies lost to the Florida Marlins at Citizens Bank Park, 4-3, they lost the chance to potentially finish with the best record in the NL.

The Phillies, who have lost three consecutive games, can finish no better than 93-69. The Dodgers clinched the NL West on Saturday and will finish with no worse than a 94-68 record.

The Phillies will host the Rockies, who are the NL Wild Card winners, in Games 1 and 2 of the NLDS on Wednesday and Thursday.

The Phillies still could have home-field advantage in the NLCS, but only if the Cardinals beat the Dodgers in the NLDS.
