Al Horford hit a huge 3-pointer against his former team and the Boston Celtics broke open a tight game in the closing minutes to finish off the Atlanta Hawks 128-120 on Thursday night for a 4-2 victory in the opening-round playoff series.

The second-seeded Celtics advance to face the third-seeded Philadelphia 76ers, who´ve been resting since completing their four-game sweep of Brooklyn last Saturday.

Game 1 is Monday night in Boston.

Marcus Smart also came up big for Boston, scoring 22 points and brilliantly running the Boston offense down the stretch.

Dejounte Murray returned to the Hawks lineup after serving a one-game suspension for bumping an official at the end of Atlanta´s Game 4 loss.

Now, State Farm Arena is wide open for the summer.
