PHILADELPHIA — Andre Iguodala made the go-ahead free throws with 2.2 seconds left and Philadelphia rallied for a 79-78 victory over top-seeded Chicago in Game 6 on Thursday night, advancing to the second round of the Eastern Conference playoffs for the first time since 2003.

The 76ers will face Boston, which beat Atlanta in six games, in the conference semifinals.

Omer Asik missed two free throws with 7 seconds left that would have given the Bulls a three-point lead. Iguodala grabbed the second miss, sprinted the length of the court, was fouled by Asik and made both free throws.

The Sixers are the fifth No. 8 seed to win a first-round series against a No. 1 seed.

Celtics 83, Hawks 80

BOSTON — Kevin Garnett had 28 points, including the jumper to give Boston the lead with 31 seconds left, and 14 rebounds as the Celtics advances to the Eastern Conference semifinals for the fifth straight year.
