Wizards 114, Mavericks 111
DALLAS -- Small forward Otto Porter racked up a career-best 28 points to lead the hot-shooting Washington Wizards past the Dallas Mavericks 114-111 on Saturday night at American Airlines Center.
The Wizards (10-12) snapped an 11-game losing streak to Dallas and won for only the second time on second half of a back-to-back this season.
Washington did so without shooting guard Bradley Beal, who's out for at least two weeks with a leg injury. Beal's absence mattered little with Porter coming through with the highest-scoring performance of his three-year career.
Porter was at his best in the third quarter as the Wizards turned a one-point game into a near rout. The Georgetown product knocked down 7 of 8 shots from the field and scored 17 points in the third alone.
Porter finished 11 of 18 from the floor, including 4 of 8 on 3-pointers. He grabbed six rebounds and doled out three assists. Porter's previous high was 23 points.
Washington shot 51.8 percent from the field for the game and outscored Dallas 31-14 in fast-break points.
Wizards point guard John Wall extended his streak of scoring at least 26 points and delivering seven assists to a career-best five consecutive games. Wall had 26 points and a season-high 16 assists.
Washington center Marcin Gortat had his fifth double-double in the last six games with 14 points and 12 rebounds. Shooting guard Jared Dudley scored 13 points.
The Wizards began to pull away early in the third quarter, racing out to a 13-point lead behind Porter. Dallas coach Rick Carlisle called two timeouts in the first four minutes of the period, but it didn't slow down the Wizards.
Their shots kept falling even as Dallas began to find their offensive rhythm. A layup from Washington reserve point guard Ramon Sessions pushed the advantage to 90-69 late in the third quarter.
The Mavericks (13-11) have dropped their first two games on a three-game homestand that ends Monday night against Phoenix. Dallas is now 5-5 at home.
Power forward Dirk Nowitzki suffered through his second straight poor outing, making just 3 of 9 shots from the floor for 13 points. The Mavs' leading scorer was 6 of 20 in Wednesday's loss to Atlanta.
Shooting guard Wesley Matthews did his best to keep Dallas close. After drilling a career-high 10-pointers and scoring 36 in last Sunday's win at Washington, Matthews hit another six from deep and scored 28.
Point guard Raymond Felton, subbing for ailing Deron Williams, cobbled together a triple-double with 10 points, 11 rebounds and 11 assists.
Backup point guard J.J. Barea (21 points) led a furious rally in the final minutes to get Dallas within a possession in the closing seconds. Barea made two free throws with 4.4 seconds left to make it 112-111.
Wall made two foul shots with 3.7 remaining before Nowitzki's 3-point try at the buzzer glanced off the front rim.
The Wizards, 6-5 away, continue their four-game road trip Monday at Memphis.
