OKLAHOMA CITY (AP) - Russell Westbrook had 24 points and 11 assists, and Kevin Durant added 23 points to help the Oklahoma City Thunder beat the Dallas Mavericks 108-70 on Saturday night in Game 1 of their first-round Western Conference playoff series.
Serge Ibaka had 17 points and nine rebounds, and Enes Kanter added 16 points and 13 rebounds for the Thunder.
It was Oklahoma City's largest victory margin in a playoff game since moving from Seattle before the 2008-09 season, and the lowest point total the franchise has allowed in a postseason game, in Seattle or Oklahoma City.
Dallas scored its fewest points ever in a playoff game, and its .298 field-goal percentage was the worst ever in a postseason game for a franchise that has existed since 1980.
Dirk Nowitzki led the Mavericks with 18 points.
