The last time the Celtics  played the Mavericks, Dirk Nowitzki  scored 37 points and had Rasheed Wallace  vowing “retribution.” For three quarters the Celtics held Nowitzki in check, but in the final 12 minutes the most under-appreciated superstar in the NBA began to get rolling.
Nowitzki shot the Mavs back into the game — and a seven-point fourth quarter lead — and the Celtics knew that if they were going to steal another one on the road, they would have to stop him to do it.
Kevin Garnett  drew the assignment down the stretch, but he was not alone. Wherever Nowitzki went, help followed. The Celtics allowed open jump shots to whomever wanted one, but wouldn’t let Nowitzki breathe. While he finished with 28 points, the Celtics held him to just one field goal in the final five minutes.
The Celtics did escape with a 102-93 win in Dallas (recap ) against a Mavs team that had been 14-2 since acquiring Caron Butler and Brendan Haywood . In doing so they not only completed the sweep of the back-to-back, they also capped off a sweep of the Texas triangle after beating Houston Friday night and San Antonio earlier in the year.
Paul Pierce , Ray Allen  and Rajon Rondo  combined for 70 points on 26-for-45 shooting, 16 rebounds and 14 assists. It was the Celtics’ fourth straight win and their fifth in the last six games. It was also their most significant win since beating the Lakers and Portland back-to-back in February.
Retribution? Maybe not, but it was certainly a satisfying win for the Celtics.
Player of the Game: Paul Pierce scored 29 points on 10-for-17 shooting, but it was his last points that were the most important. With the Celtics clinging to a one-point lead, Pierce drained a 3-pointer from the top of they key. He then came up with a steal on the other end and found Rajon Rondo for an easy layup and a 99-93 lead. It was Pierce’s third straight game where he has scored more than 20 points.
Turning Point: After J.J. Barea sank a 3-pointer to put Dallas ahead, 82-75, the Celtics looked like they might be in trouble. But Ray Allen came back and hit a 20-footer and then a long 3-pointer to get the C’s back within two, 84-82. The Mavs are a notorious second-half team and looked like they were about to make one of their patented fourth-quarter runs before Allen’s big shots.
* The C’s opened up a 60-52 lead with a 12-5 run to start the second half, but the Mavericks rallied, highlighted by an emphatic dunk by Caron Butler on Kendrick Perkins .
* Both teams got off to a slow start as the Celtics missed their first five shots and the Mavs missed five of their first six. But things picked up quickly after that and the Celtics took a 30-24 lead after one quarter.
* Jason Terry  scored 14 points in the first half. The Mavericks bench completely outplayed the Celtics reserves.
* The teams combined for 26 free throws in the first half.
* Garnett had a strange stat line in the first half when he had eight rebounds and five steals to go with just two points. Garnett missed all four shots that he took, but he appeared to be moving well.
