PHILADELPHIA — Freddie Freeman hit a three-run homer to back Mike Minor and the Atlanta Braves roughed up Roy Halladay to move closer to clinching a postseason berth with an 8-2 victory over the Philadelphia Phillies on Saturday. The win coupled with Milwaukee's 10-4 loss to Washington reduced Atlanta's magic number for securing a playoff spot to three. The Braves were up 8½ games through Sept. 5 last year, but went 9-18 down the stretch and were overtaken by St. Louis on the final day of the season.
