PRO BASKETBALL—In one of the NBA's two-out-of-three mini-series, Philadelphia swept Indiana. After a 124-108 victory at home in which Julius Erving scored 32 points, the 76ers triumphed 96-85 in Indianapolis to earn a place opposite Milwaukee in the conference semifinals. Chicago, meanwhile, won its spot against Boston, beating New York 90-80 (holding the Knicks to their lowest point total of the season) and 115-114 in overtime to extend its winning streak to 10 games. In the Western Conference, the competition was tighter. Kansas City trailed Portland 86-76 with just over six minutes remaining in the first game of their series, but the Kings rallied to tie the score at 90-90 on a driving layup by Otis Birdsong with a second to play and went on to win 98-97 in overtime. The second K.C. Portland game also went into OT; this time the Blazers triumphed 124-119 behind 40 points by Mychal Thompson.

HOCKEY—With a 7-3 victory at Buffalo on the final day of the regular season, the Islanders won the NHL regular-season title for the second time in three years, with a total of 110 points. With the winning score in a 5-4 victory at Washington, Islander Mike Bossy finished with 68 goals—eight short of Phil Esposito's 1970-71 single-season record. St. Louis, which tied last-place Winnipeg (5-5) in its final game, finished second with 107 points. Edmonton's Wayne Gretzky had three assists in a 5-2 triumph at Pittsburgh, two more in a 4-4 tie with Colorado and a goal and four assists in a 7-2 win over Winnipeg to bring his assists for the season to 109, surpassing the record of 102 set by Bobby Orr in 1970-71, and his total points to 164, 12 more than Esposito's mark of 1970-71. Gretzky also became the first NHL player to average more than two points a game; previously the highest average had been Bruin Bill Cowley's 1.97 in 1943-44. Winnipeg, Detroit, Colorado and Hartford had earlier been knocked out of playoff contention, but Washington was only one point behind the 16th-place Maple Leafs going into its game with Detroit on Sunday. Toronto had tied Chicago 2-2 and Quebec 5-5 earlier in the week and needed either at least a tie in a return match against the Nordiques or a Capitals' loss to clinch a playoff spot. Washington won 7-2, Dennis Maruk getting a hat trick, but so did Toronto, 4-2.
