PRO BASKETBALL—Dave Cowens sank his first 11 field-goal attempts and finished with 37 points as Boston, ahead by 22 points in the third quarter, held on to beat Philadelphia 124-119 and even their semifinal series at 2-all. Earlier in the week Guard Henry Bibby came off the bench to toss in 22 points and lead the 76ers past the Celtics 113-101 in a game from which Celtic Coach Tom Heinsohn was ejected in the second quarter. Behind 16-1 after six minutes of play, Washington rallied for a 111-101 decision over Houston in Game One of their series as rookie Forward Mitch Kupchak had 16 rebounds and a career-high 32 points. Marvelous Moses Malone countered with a career high of his own, totaling 31 points and grabbing 26 rebounds as the Rockets beat the Bullets 124-118 in overtime in Game Two. It was Kupchak's turn again in Game Three as he scored 23 points to lead the Bullets to a 93-90 win. Rick Barry, who punched at (but missed) an official as Golden State lost to Los Angeles 95-86 on Friday, was anything but punchless on Sunday, scoring 40 points to lead the Warriors to a 109-105 victory. The Lakers, with Kareem Abdul-Jabbar averaging 31.7 points for three games, lead the series 2-1. Maurice Lucas hit on a 14-foot turnaround jumper with 11 seconds remaining to lift Portland past Denver 101-100 in the first game of their series. The Nuggets evened the series with a 121-110 victory in Game Two, but the Trail Blazers bounded back 110-106 in Portland as Lucas scored 27 points, increasing his three-game total to 79.

HOCKEY—NHL: Two freak plays figured importantly in the last two games of the Boston- Los Angeles series (page 78). In Game Five, Bruin Defenseman Brad Park accidentally kicked the puck into his own net for the Kings' winning goal. Two nights later L.A.'s Dave Hutchison broke his stick during a Boston power play, giving Gregg Sheppard plenty of room to beat Rogatien Vachon for the game-and series-winning goal with 7:02 to play in the third period. Philadelphia temporarily put to rest the "away-ice advantage" theory by beating Toronto 2-0 at the Spectrum as Reg Leach scored both goals and Wayne Stephenson stopped 21 shots. For the Leafs, it was the first time they had been shut out all season. Worse still, they lost regular Goaltender Mike Palmateer for the rest of the playoffs with torn knee ligaments. The rest of the playoffs, as it turned out, meant one more game. Reviving the away advantage, the Flyers eliminated the Maple Leafs 4-3 at Toronto on Defenseman Jim Watson's goal with 1:00 to play. Then the Flyers lost to Boston 4-3 in overtime at home Sunday night in the opening game of their semifinal series. In Game One of the other semifinal, Montreal fell behind New York 3-1 early in the second period as Billy Harris scored the hat trick for the Islanders. Murray Wilson closed New York's lead to 3-2 with a second-period score, and linemates Guy Lafleur and Steve Shutt scored within 2:00 of each other early in the final period to give the Canadiens a 4-3 triumph.
WHA: Home ice was no disadvantage in the Winnipeg- San Diego series.

Houston ousted Edmonton four games to one in the other Western quarterfinal. In the East, Quebec's Richard Brodeur shut out New England 3-0 as the Nordiques bounced the Whalers four games to one. In the first game of the semifinals, Quebec beat Indianapolis 3-1.
