DALLAS — Cooper Flagg scored 22 points and had a soaring one-handed dunk during the decisive run, helping the Dallas Mavericks beat the Toronto Raptors, 139-129, on Sunday night for their first victory with the No. 1 overall pick.
Anthony Davis had 25 points and 10 rebounds as the Mavericks won the third of five consecutive home games to start the season, a night before they face defending champion Oklahoma City to finish a back-to-back.
Scottie Barnes had 33 points and 11 rebounds for the Raptors, who play another game in Texas at San Antonio on Monday night.
Flagg started a 13-0 run in the third quarter with a bucket and finished it by taking a bounce pass from D’Angelo Russell in transition, dunking over Sandro Mamukelashvili and getting fouled. The free throw put Dallas up 95-85.
