The Boston Celtics rallied together once Rajon Rondo went down and rattled off seven straight wins -- six at home.

But in the midst of a brutal road stretch since the All-Star break, wins haven't come as easy.

Avery Bradley had 22 points in the Celtics' 109-101 triumph over the Philadelphia 76ers.

"He was good all-around, he's confident," Celtics head coach Doc Rivers said of Bradley.

The Celtics, who have won three in a row, are in the middle of playing 9-of-11 games on the road. They went 2-3 during a five-game road trek right after the break before defeating Golden State Friday in Beantown.

Boston improved to 11-18 away from home, opposed to a 21-8 mark at TD Garden.

Paul Pierce tallied 18 points, 11 rebounds and seven assists, while Kevin Garnett added 18 points, six helpers and five boards in the victory.

Thaddeus Young had 19 points and 10 rebounds to lead the Sixers, who have lost 28 of their last 40 tilts since beginning the year 11-8. They had won six of their last seven meetings against Boston in Philadelphia -- including the postseason.

"They move the ball, they got the guys, they're a good group," Sixers guard Royal Ivey said of Boston.

Already holding a 79-74 lead after three, the Celtics began the fourth on a 12-2 run and never looked back. Jordan Crawford totaled eight points during the surge, which was capped on his second 3-pointer during the spurt for a 91-76 Boston edge with 8:16 left.

The Sixers never got within less than seven the rest of the way.

Boston led 26-23 after a quarter of play and took a 53-46 cushion into the break.
