A roundup of the week May 1-7

BASKETBALL—NBA: There were three minutes remaining in the second period, and Portland had just overcome a six-point deficit to lead Seattle 49-43 in their quarterfinal playoffs. The Sonics then scored 12 consecutive points to take a 55-49 halftime lead. From that point, the defending-champion Trail Blazers, without three key players—Bill Walton, Lloyd Neal and Bob Gross—could come no closer than four points. The Sonics won 105-94, their 17th straight home win, including five in the playoff's, to move into the Western Conference finals against Denver, which defeated Milwaukee 116-110 as David Thompson scored 37 points and Anthony Roberts 26. In its first semifinal game, Seattle converted 47 of 62 free throws to set an NBA record for most free throws made in a regulation-time playoff game, but lost to the Nuggets 116-107. After losing to Philadelphia 110-104, Washington beat the Sixers 123-108 and 121-105 to lead their Eastern Conference playoff three games to one (page 24).

BILLIARDS—RAYMOND CEULEMANS won his 15th World Championship 3-Cushion Tournament in Las Vegas (page 78).

BOXING—WBA light-heavyweight champion VICTOR GALINDEZ of Argentina retained his title on a unanimous decision over Alvaro Lopez of Stockton, Calif. in Lido Di Camaiore, Italy.

Undefeated YOKO GUSHIKEN retained his WBA junior flyweight title with a 13th-round knockout of Jaime Rios in Tokyo.

GOLF—TOM WATSON won the $200,000 Byron Nelson Classic in Dallas for his third victory this season. His eight-under-par 272 beat Lee Trevino by one stroke.

GYMNASTICS—KATHY JOHNSON won the floor exercise, balance beam and overall title at the U.S. Federation women's championships in Uniondale, N.Y. MARCIA FREDERICK scored the first perfect 10 in national competition to take the uneven parallel bars. SHARON SHAPIRO and RHONDA SCHWANDT tied for first in the vault.

HOCKEY—NHL: It was a case of dèjà vu for the Boston Bruins last week—not once, but twice. Duplicating his game-winning goal that led the Bruins to a sweep of the Flyers in the Stanley Cup semifinals last season, Rick Middleton scored the deciding goal in the opener again this year for a 3-2 Boston win. In the second game, Middleton scored to break a 5-5 tie and Boston went on to win a 7-5 victory. Sunday night the Flyers beat the Bruins 3-1, to trail in the playoffs two games to one (page 60). In the opening game of their semifinal Stanley Cup playoff, the Montreal Canadiens defeated the Toronto Maple Leafs 5-3 as Yvan Cournoyer got his 62nd and 63rd career playoff goals to put him in fourth place on the NHL alltime playoff scoring list. Guy Lafleur scored two goals and assisted on another by Defenseman Larry Robinson as Montreal beat Toronto for a 2-0 series lead. The Canadiens then made it 3-0 by beating Toronto 6-1.

WHA: It's on to Winnipeg for New England. Losing only one game to Quebec, the Whalers advanced by winning Game 5 in Springfield, 6-3. The Nordiques, however, didn't go easily. In Game 3 they rallied from a 4-0 deficit to tie the score 4-4 as Marc Tardif had three assists. But with 50 seconds remaining, New England's Larry Pleau shot a backhander that slid between Quebec Goalie Ken Broderick's leg pads and into the net for a New England victory. In Game 4 the Nordiques scored all of their goals on power plays, while losing 7-3.

HORSE RACING—AFFIRMED ($5.60), Steve Cauthen up, won the 104th Kentucky Derby, covering the 1¼ miles in 2:01[1/5] to finish a length and a half ahead of Alydar, who had a length and a quarter on Believe It (page 18).

MOTOR SPORTS—PATRICK DEPAILLER, driving a Tyrrell-Ford, finished 22.45 seconds ahead of Niki Lauda's Brabham-Alfa to win the Monaco Grand Prix in Monte Carlo. In his first Grand Prix victory in 69 races, Depailler averaged 80.359 mph for the 154.35 miles.

SOCCER—NASL: Temporarily knocked out of first place in the Eastern Division by Washington's 2-0 defeat of Colorado, the undefeated Cosmos retook the lead by one point by beating Detroit 2-0. It was their 15th straight home victory, tying a league record. It seems it will be a while before things begin to look up for the Memphis Rogues, however. Fort Lauderdale handed Memphis its sixth straight defeat, 3-2. Tulsa's Billy Caskey scored two goals to lead the Roughnecks to a 3-0 win over Oakland. Earlier, Tulsa shut out Dallas 1-0 on a goal by Jim Redfern.

ASL: In soccer, height usually doesn't give one player an advantage over another, but when Kevin McCarthy of the New York Apollo fed Mike Mancini a pass in the air, the 6'4" Mancini headed the ball into the net for the only goal scored during a 1-0 New York defeat of New Jersey. Alan Sproates got an unassisted goal at the 85-minute mark to lead Los Angeles to a 1-0 victory over California.

SQUASH TENNIS—PEDRO BACALLAO won the U.S. Nationals for the 10th consecutive time, beating Bill Rubin 15-8, 15-7, 15-4 in New York.

WTT: In their second meeting this season, Martina Navratilova beat Chris Evert 6-3 as Boston won its fourth straight, defeating Los Angeles 25-22. The Strings were in better form earlier in the week, taking every match against New Orleans except the women's doubles for a 30-21 victory. Four of New York's six wins this season have been against Indiana. The Apples beat Indiana 31-25 as Billie Jean King took her seventh consecutive singles match, against Dianne Fromholtz, 6-4. The Apples also defeated the Strings 31-18 as King beat Evert 6-4. Led by Virginia Wade's 6-0 trouncing of Kerry Reid, the Golden Gaters topped San Diego 27-23.

TRACK & FIELD—JAMES BUTTS set an American record of 56'5½" in the triple jump at the UCLA Invitational track meet. The former record of 56'5¼" was established by Tommy Haynes in 1975. At the same meet, PATTY VAN WOLVELEARE set an American record of 13.21 in the 100-meter hurdles while finishing second to Lorna Booth of Great Britain. The previous record of 13.24 was set by Jane Frederick in 1977.
