PRO BASKETBALL—Three of the four division leaders seem to have gotten complacent, as only the Pistons, No. 1 in the Central, played better than .500 ball. Detroit, whose 56-18 record at the end of the week was the best in the NBA, had its eight-game winning streak snapped by the Trail Blazers. 118-100, but bounced back by beating the Bulls 115-108 and, in overtime, 114-112. In the latter victory the Pistons' Isiah Thomas and Chicago's Bill Cartwright were ejected for fighting. Cartwright was fined $2,500 and suspended for one game: Detroit's Mark Aguirre was fined $2,000 for "acting as other than a peacemaker"; and Thomas, who was deemed to have started the set-to, was fined $5,000 and suspended for two games. Worse still, Thomas broke his left index finger and may miss the rest of the regular season. The Lakers lost to the Jazz 99-97 and to the Warriors 122-116 and saw their Pacific Division lead over the Suns, who won three straight, shrink to 1½ games. In the Atlantic Division the Knicks suffered their fourth loss in their last seven home games, falling to Philadelphia 124-113. New York also lost 115-105 on the road to the Nets, who got 29 points from Chris Morris. Utah, the Midwest Division leader, went 2-2 for the week and lost ground to second-place Denver, which was 3-0 and trailed the Jazz by 3½ games. One of the Jazz's defeats came at the hands of the Nuggets, whose Alex English had 26 points in a 110-106 game, giving him 2,001 for the season. English became the first NBA player to score at least 2,000 points in eight consecutive seasons.

HOCKEY—In the first round of the NHL playoffs, the Penguins swept four games from the staggering Rangers, who, under general manager-turned-coach Phil Esposito, ended their season with six straight defeats. Pittsburgh, which hadn't made the playoffs since 1982 and had won only three of 12 playoff series in its 21-year history, will face the winner of the Caps-Flyers series, which was tied at two games apiece after Philly got four goals in the second period Sunday en route to a 5-2 victory. The Sabres scored the first nine goals of their Adams Division playoff with the Bruins, winning the opener 6-0 and then taking a 3-0 lead in Game 2 before folding. Boston won that one 5-3 and then got two game-winning goals from Cam Neely to lead the series 3-1. In the other Adams Division bracket, the Canadiens finished off the Whalers in four straight. In the Norris Division the Blues' Brett Hull scored four goals as St. Louis took a 3-1 lead over the North Stars, and the surprising Blackhawks, paced by Duane Sutter's two game-winning goals, led the Red Wings 3-1. The Flames were upset 4-3 by the Canucks in the first game of their Smythe series when a shot by Vancouver's Paul Reinhart at 2:47 of OT slipped through the legs of Calgary goalie Mike Vernon. Vernon later redeemed himself by shutting out the Canucks 4-0, but Vancouver got a goal and three assists from Trevor Linden in a 5-3 win in Game 4 to even the series at 2-2. Also in the Smythe, the Oilers spurted to a 3-1 lead over the Kings (page 26).
