DALLAS (AP) — J.J. Barea scored 20 points with a key 3-pointer that helped put Dallas in control in the fourth quarter, and the Mavericks won their sixth straight home game, beating the Boston Celtics 113-104 on Saturday night.

Harrison Barnes also had 20 points, teenage rookie Luka Doncic totaled 15 points and matched Barea with eight assists while starting at point guard with Dennis Smith Jr. sidelined by a wrist injury as the Mavericks (9-9) got back to .500 with their seventh win in nine games.

It’s the latest Dallas has been .500 or better since the end of the 2015-16 season, and it’s the first six-game home winning streak for the Mavericks in almost two years.

Jayson Tatum scored 21 points and Kyrie Irving and Marcus Smart had 19 apiece for the Celtics, who followed a win with a loss in a back-to-back for the third straight time this season a night after winning in Atlanta.

Boston was without Gordon Hayward, who sat with soreness in his surgically repaired left ankle, in part because of playing on consecutive nights.
