Milwaukee led the Central Division despite a rollercoaster week that included a 106-101 defeat of the Pistons and an embarrassing 103-89 drubbing at the hands of the Mavericks. In the Atlantic Division, No. 1 Boston enjoyed a pre-Christmas feast by devouring the 76ers (115-105) and the Hornets (115-96) before having the Hawks for dessert with a 132-104 victory in the conclusion of a Nov. 28 game that had been suspended because of condensation on the Boston Garden floor.

(38°) for Minneapolis, where it was-10° outdoors but temperate in the Metrodome, to end the Vikings' playoff hopes with a 28-24 victory.

HOCKEY—The Kings continued to chase the Smythe Division-leading Flames and even cooled them off a little as Luc Robitaille knocked down a clearing pass and skated in all alone for the winning goal in overtime of a 4-3 game. The Flames' 3-2 loss to the Canucks earlier in the week and a 6-2 defeat by the Oilers left them three points ahead of L.A. The Rangers survived one close call, coming back from a 3-1 deficit in the second period to beat the Capitals 5-3, and then fell 4-1 to the Maple Leafs, 3-1 to the Canadiens, who broke a scoreless game with a three-goal burst in the second period, and tied the Bruins 5-5. Those losses cut New York's Patrick Division lead to two points over the second-place Devils. Boston had a hellish time with the Devils, who got five goals on 13 shots against Bruin goalie Reggie Lemelin. He was yanked in the second period of the 8-3 loss. The Bruins bounced back with a 4-1 win over the Sabres and a 6-2 rout of the North Stars, and finished the week with a seven-point Adams Division lead. Dirk Graham's shorthanded goal with 4:25 to play gave the Blackhawks a 3-2 win over the Capitals, but when Chicago, the Norris Division leader, met the second-place Blues, it was St. Louis that was long on shorthanded successes. The Blues scored three shorthanded goals in a 5-0 whipping of the Blackhawks. Goalie Vincent Riendeau got the shutout for St. Louis, which finished the week three points behind Chicago.
