The Dallas Mavericks defeated the Boston Celtics 94-89 on Monday night behind 19 points and six rebounds from Dirk Nowitzki.
The Celtics (22-46) have now lost five games in a row and became the first team in NBA history to go winless against the Western Conference on the road in a single season. Conversely, the Mavericks (41-27) have won three games in a row and six of their last 10.
In a sloppy affair that saw the Celtics out-rebound the Mavericks by 21 overall and 15 on the offensive glass, both squads shot below 42 percent, with Boston bottoming out at 37 percent despite shooting 41 percent from three.
After ripping off a 12-0 run in the third quarter, the Celtics flatlined for a majority of the fourth and surrendered 30 points in the game's final frame, the only quarter in which either team hit the 30-point mark.
Monta Ellis added 17 points and four assists, but turned the ball over a team-high five times in the win. Devin Harris was steady off the bench to the tune of 12 points and six dimes while Shawn Marion tacked on 11 points, six rebounds and two steals in 34 minutes.
Jerryd Bayless led the Celtics with 19 points on 6-of-16 shooting (3-of-5 from three), but was unable to convert on a game-tying bucket when Boston trailed by three with under 10 seconds remaining.
Jared Sullinger and Kelly Olynyk were both big off the bench, contributing 13 and 16 points, respectively, but the latter was the only Celtics player to record a plus/minus rating better than plus-one in the loss.
Next up for the Celtics is a matchup with the Miami Heat on Wednesday while the Mavericks are set to host the Minnesota Timberwolves after a day off on Tuesday.
