PRO BASKETBALL—Seattle, Washington and San Antonio took big leads in their best-of-seven quarterfinal playoffs, while Phoenix got the edge on Kansas City in their series. Seattle Guard Gus Williams scored 124 points in four games to more than offset Kareem Abdul-Jabbar's 119 as the SuperSonics gained a 3-1 advantage over the Lakers. After Seattle won the opener 112-101, the teams split overtime games, with the Sonics winning the first 108-103 behind Williams' 38 points and the Lakers the second 118-112, with Abdul-Jabbar scoring 32. Williams pumped in 30, and the Lakers' Norm Nixon missed a 20-foot shot at the buzzer as Seattle won Game 4 117-115. After the pesky Hawks beat the Bullets 107-99 in Landover, Md. to tie their series 1-1, Washington ended Atlanta's 17-game home-court winning streak, 89-77, and then triumphed 120-118 in overtime at the Omni. Julius Erving blew hot and cold, and so did the 76ers, who found themselves within one loss of elimination. Erving scored 39 in Philadelphia's 123-115 defeat of the Spurs in Game 3, but he was held to 15—only four of them in the first three quarters—as the Spurs won the fourth game 115-112 behind George Gervin's 32 points. Gervin had 52 points in San Antonio's earlier 123-115 and 121-120 triumphs. Phoenix took a 2-1 lead over Kansas City as the Suns' bench accounted for 51 points, including 16 from reserve Guard Mike Bratz, in a 108-93 victory. Phoenix overcame a 13-point third-quarter deficit to win the opener 102-99, and the Kings won the second game 111-91.

HOCKEY—NHL: The Islanders, Canadiens and Bruins all benefited from a week of rest, having had a bye in the first round of the playoffs, and swept through their best-of-seven quarterfinal series. The Islanders extended Chicago's playoff losing streak to 16 games with a 3-1 clinching victory. Right Winger Mike Bossy almost single-handedly beat the Black Hawks in the team's first two meetings, scoring three goals on four shots in the 6-2 opener and tapping in a pass from Center Bryan Trottier in the second game, the first 1-0 overtime playoff contest since 1954. Glenn Resch followed Billy Smith's shutout with one of his own as the Islanders beat Chicago 4-0 two nights later. The Toronto Maple Leafs, who had swept Atlanta the week before, had the tables turned on them when Montreal reached the Stanley Cup semifinals with a 5-4 overtime win on Larry Robinson's goal. Jacques Lemaire scored two goals in the Canadiens' 5-2 first-game victory, and Bob Gainey did the same two nights later as Montreal won 5-1. The defending champions' third win, by a 4-3 margin, came on Cam Connor's goal in the second overtime. After beating Pittsburgh 6-2 in the opener, Boston had all it could handle in edging the Penguins 4-3 and 2-1. The Bruins wrapped up the series with a 4-1 win. The New York Rangers took a commanding 3-1 lead in its playoff series with Philadelphia with three straight victories (7-1, 5-1 and 6-0), after the Flyers won the opener 3-2 in overtime (page 26).
WHA: The league wrapped up its final regular season with first-place Edmonton routing Winnipeg 9-3 as Stan Weir, Ron Chipperfield and Brett Callighen scored two goals apiece.

Real Cloutier of Quebec won his second scoring championship with 75 goals and 54 assists, and Edmonton's Dave Dryden, whose brother Ken was the leading goaltender in the NHL this season, was the best in his league with a 2.89 goals-against average. The playoffs opened with New England and Cincinnati splitting the first two games of their best-of-three series.
