A roundup of the week March 26-April 1

PRO BASKETBALL—Paced by David Thompson's 31 points, Denver beat San Diego 130-121 for its seventh straight victory. The streak enabled the Nuggets to take over first place in the Midwest Division from the struggling Kings, who had held down the top spot since Nov. 17. Against the Clippers, who got 42 points from Lloyd Free, George McGinnis suffered an ankle injury that will sideline him for six weeks. The defeat dropped San Diego, loser of four in a row, 2½ games behind Portland in the race for the final Western Conference playoff spot (page 24). Following a 122-110 overtime loss to Milwaukee, which has won 10 of its last 13, the Blazers handed Atlantic Division champ Washington its worst home-court defeat in four years. Center Tom Owens tossed in 30 points in the 132-104 victory, Portland's seventh in its last eight games. Moses Malone's two free throws with time having expired gave Houston a 117-116 win over Central Division leader San Antonio and pulled the Rockets to within a half game of first place. Malone finished with 36 points and 19 rebounds. The Spurs' George Gervin, the league's No. 1 scorer with a 29.6 average, poured in 46. On the same night, Walter Davis pumped in 40 and Paul Westphal added 25 to lift Phoenix, winner of five straight, to a 113-111 win over Seattle. The Sonics, however, maintained a two-game lead over the Suns in the Pacific Division by beating Detroit 123-103 for their eighth win in their last nine starts. Earlier, Seattle Guard Gus Williams had scored 38, equaling his career high, in a 111-101 defeat of Kansas City and 30 in a 115-109 win over San Diego. Golden State's Robert Parish had 30 points and pulled down a career-high 32 rebounds in a 114-98 defeat of New York, and Rich Kelly had 81 points and 61 rebounds in three games for New Orleans. With the 12th of his 23 assists in a 124-113 loss to Los Angeles, Kevin Porter of Detroit became the first NBA player to hand out 1,000 in a season.

HOCKEY—NHL: Boston and Chicago joined the Islanders and Canadiens as division winners. The Bruins wrapped up the Adams title with a 4-1 defeat of Washington, and the Black Hawks, led by Grant Mulvey's hat trick, clinched first in the Smythe with a 6-1 win over the Islanders. Two nights later, the Islanders snapped Buffalo's five-game victory streak as Chico Resch stopped 32 shots en route to a 2-0 shutout. By beating Pittsburgh 5-3, Montreal halted the Penguins' unbeaten string at 10 and gained a two-point lead over the Islanders in the race for the league's best record and home-ice advantage in the playoffs. Earlier, the Penguins had secured a playoff berth with a 7-1 rout of the Rangers that featured a hat trick by Greg Malone. Led by Lanny McDonald's three goals, Toronto got a playoff spot with a 6-2 defeat of Minnesota, and Los Angeles landed a berth by beating Detroit 5-4. The remaining slots will be filled by Philadelphia, the Rangers, Atlanta, Vancouver and Buffalo.

WHA: Back-to-back shutouts—3-0 over Edmonton and 2-0 over Winnipeg—lifted Quebec to within a point of the first-place Oilers. Richard Brodeur was in the nets both nights for the Nordiques, and Real Cloutier picked up his 72nd and 73rd goals. A single point is also all that separates third-place New England from fourth-place Winnipeg. At stake in the race for third is a bye into the semifinal round of the playoffs.
