PRO BASKETBALL—For six games, Philadelphia was criticized for not playing any defense against Boston in their quarterfinal playoff battle. For example, Jo Jo White scored at will Friday night, pumping in 40 points in a 113-108 Celtic win that forced the series to the seventh game. On Sunday it was a different story, however. White was held to zero points in the second half while 76er Guard Lloyd Free (27 points) bombed the Boston defenses from all over the floor as Philadelphia outdefensed Boston 83-77 and took the series 4-3, eliminating the defending champions. It was only the second time in 13 occasions that the Celtics had lost a seventh game in the playoffs. Houston won three straight to eliminate Washington 4-2. Tiny Calvin Murphy was the hero of Game Five, hitting for 40 points in a 123-115 Rocket victory. And muscular Mike Newlin scored 15 of his 21 points in the fourth quarter of Game Six to assure Houston's 108-103 win. Golden State squared its series against Los Angeles with a 115-106 win in Sunday's sixth game, the 16th straight time (over four years) that the Warriors had beaten the Lakers in Oakland. Averaging 37.3 and 29.2 points per game respectively, Kareem Abdul-Jabbar and Rick Barry (page 63) turned the series into a personal scoring duel. Denver topped Portland 114-105 in overtime to cut the Trail Blazers' series lead to 3-2 (page 22).
GOLF—Leading by as many as seven strokes in the final round, GENE LITTLER coasted to a three-shot victory over Lanny Wadkins in the Houston Open. Littler finished at 12-under-par 276 and earned $40,000 for his 29th tour victory.

HOCKEY—NHL: Philadelphia will be at home until October. Stanley Cup finalists the past three years, the Flyers ran into surprising Boston in the playoff semifinals and were rudely eliminated four games to zilch [page 16). "Probably the greatest hockey game I've ever played in" was Bruin Captain Wayne Cashman's description of Boston's 5-4 double-overtime victory in Game Two. When Bruin Right Winger Terry O'Reilly beat Wayne Stephenson for the decisive goal after 30:07 of sudden death, he called it "the biggest thing that ever happened to me." Montreal took a three-games-to-one lead over the New York Islanders in the other semifinal as Goaltender Ken Dryden had a pair of shutouts. Jimmy Roberts' shorthanded goal at 7:46 of the third period of Game Two broke a scoreless game and led to a 3-0 Canadien win. But the Islanders bounced back on Thursday with a 5-3 win, handing the Canadiens only their second defeat in their last 41 games. Denis Potvin made up for two defensive lapses that resulted in Montreal goals with two goals of his own, and Center Jude Drouin contributed three assists. It was all Montreal in Game Four, however, as Steve Shutt, Guy Lafleur and Roberts scored during an all-out Canadien attack in the opening 8:18. New York never recovered, never tested Dryden and lost 4-0.
WHA: Quebec's Paulin Bordeleau scored his third goal of the game at 5:29 of overtime to give the Nordiques a 6-5 decision and a three-games-to-none lead over Indianapolis in their semifinal series. Racer Coach Jacques Demers blamed that loss on Goalkeeper Michel Dion and replaced him with Paul Hoganson for Game Four. Indianapolis responded with a 2-0 victory in which Hoganson turned back 22 Nordique shots. Winnipeg beat Houston 6-4 to take a 3-1 lead in their semifinal series. Peter Sullivan scored the game-winning goals in Winnipeg's two 4-3 victories, one after 8:05 of overtime, the other with 1:36 to play in regulation. The Aeros countered with the father and the son, Gordie and Mark Howe, who accounted for five goals as Houston trounced the Jets 7-2 in Game Two.
