The Celtics blew away their lead in the fourth quarter, but two huge OTs by Rajon Rondo lifted the Celtics to a 117-115 win over the Mavs. That ends Dallas's three-winning streak on its tracks.

O.J. Mayo and Darren Collison combined for 40 points and willed their team back into the game, but it was too little and too late. A costly turnover with five seconds left in the 2nd OT would finish the Mavs' hopes to victory.

Paul Pierce lead the Celtics with 34 points and Rajon Rondo contributed with a huge 16-9-15 stat line.
