WASHINGTON -- Harrison Barnes scored 22 points and the Dallas Mavericks opened the fourth quarter with a 24-7 run as they rallied past the Washington Wizards for a 112-107 win on Wednesday night.

Dirk Nowitzki had 10 of his 20 points in the fourth quarter for the Mavericks, who swept the season series from the Wizards. Dallas had lost two in a row, including 100-78 at the Toronto Raptors on Monday. Seth Curry had 19 points, Nerlens Noel 12 and Nicolas Brussino added 11.

John Wall had 26 points and 11 assists for the Wizards (41-26). Washington returned home after a 4-1 Western Conference road trip highlighted by several massive comeback wins and capped by Monday's 119-104 loss at the Minnesota Timberwolves. Bradley Beal scored 24 points.

Poor defense plagued the current third seed in the East throughout the trip. That didn't change with the return home where they owned a 26-9 record. Dallas shot 50.6 percent from the field and 14 of 32 on 3-point attempts.

Brussino drained back-to-back 3-pointers and Noel dunked an offensive putback for a 97-87 lead with 4:46 left after trailing 74-62 in the third quarter, capping a 35-13 run.

The Mavericks kept the comeback door open by missing four of eight free throws. Wall sank two for Washington as the Wizards trailed 109-107 with six seconds left, but Dallas made three of four from the line to seal the win.

Bojan Bogdanovic scored 19 points for the Wizards, who lost 113-105 at Dallas on Jan. 3. Washington went 25-7 in between losses to Dallas. Otto Porter had 14 points and 10 rebounds.

Nervous energy spread across the home crowd as Wall limped off the court with 1:26 remaining in the first half after he awkwardly fell following a layup attempt Noel blocked. Moments after Washington announced the All-Star suffered a sprained left foot, Wall bounded back onto the court and started the second half with the Wizards leading 57-53.

He finished with his 44th double-double of the season and played the entire third quarter, finishing the period with six points and four assists as Washington pushed the margin to 12. Barnes scored 13 in the third period.
