PRO BASKETBALL—The Los Angeles Lakers beat the Dallas Mavericks 117-102 to win the NBA's Western Conference crown four games to three, the home team winning every game. In Game 6, the Mavericks survived a Laker rally when center James Donaldson thwarted a drive by forward James Worthy in the game's final seconds to preserve a 105-103 victory. Worthy's 28 points in Game 7 helped the Lakers knock out the tenacious Mavs. Los Angeles shot 53.4% for the series, an NBA playoff record for seven games. The Lakers now play the Detroit Pistons in the NBA finals.

In Game 5 against Boston, Isiah Thomas scored 35 points, 16 in the fourth period, as the Pistons overcame a 16-point Celtic lead and the Boston Garden mystique to come away with a 102-96 win. In Game 6, with Dennis Johnson, Danny Ainge and Robert Parish hobbled with injuries, K.C. Jones, in what would be his last game as Boston's coach, used all 12 of his players, but his team could not keep up with the younger Pistons, who won 95-90.
