DALLAS (AP) _ Dominique Wilkins said he was exhausted after Atlanta's 113-105 NBA victory over the Dallas Mavericks Friday night.

The Hawks' All-Star forward had every reason to be tired, scoring 32 points in leading Atlanta to its ninth straight victory,

''It was a very hard-fought game,'' Wilkins said. ''Dallas is very physical. You know they like to post-up down low. But the way we played physically down the stretch, and forced some turnovers, we deserved to win.''

Dallas Coach Dick Motta said the game was almost ''playoff caliber.''

''Atlanta just beat us tonight,'' Motta said. ''I thought the intensity was there for both teams. Atlanta has the best one-to-12 man squad I think we have faced this season. I know they were the most physical team we have faced all year.''

Dallas managed to tie the game twice in the third period, the last at 4:12 when guard Rolando Blackman hit two free throws to make it 68-68. Atlanta then took the lead for good by outscoring the Mavericks 12-7 for an 80-75 advantage at the end of the quarter.

In the fourth period, Mark Aguirre, who had 32 points, scored 10 straight as Dallas cut Atlanta's lead to 95-93 with 4:24 remaining. But the Hawks went on a 10-4 run for a 105-97 margin.

The loss was Dallas' first after seven straight home victories. The Mavericks now are 27-6 in Reunion Arena.

Forward Kevin Willis had 23 points and 11 rebounds for the Hawks. Blackman had 20 points for Dallas.

The Mavericks, who shot only 45 percent to 55 percent for Atlanta, made only one of 13 three-point field goals.

But Blackman's 3-pointer with 30 seconds left in the game gave Dallas 178 for the year, breaking the NBA record of 177 it shared with the 1979-80 San Diego Clippers.
