A roundup of the week March 4-10

PRO BASKETBALL—The Detroit Pistons lost the use of their home court for the rest of the regular season when the roof of the Pontiac Silverdome caved in after a heavy snowfall. The Pistons beat New York 114-90 in their new home away from home, the Joe Louis Arena, before losing there to Utah 122-114. On the road the Pistons squeezed out a 115-113 victory over the Hawks despite a career-high 48 points by Atlanta's Dominique Wilkins. San Antonio, sans George Gervin, beat Philly 109-103, causing Philly to shake up its starting lineup. Andrew Toney and Charles Barkley went to the bench, Clint Richardson and Bobby Jones came off it. That worked well for two games as the Sixers beat Atlanta 96-86 and Seattle 128-114, then went kaput in a 131-129 double OT loss to New York. Eastern leader Boston beat the Knicks and Dallas, 110-102 and 133-122, but fell 107-104 to Chicago. Midwest leader Denver lost 142-140 to Kansas City but beat Houston 133-131 in double OT and Indiana 126-116 at home to extend its home win streak to 16, the longest in the team's nine-year NBA history. The Lakers, firmly atop the Pacific, massacred Golden State 145-119—the fourth time this season they've whipped the Warriors by more than 20 points—and Cleveland 133-106. Milwaukee pummeled Seattle 102-87, Kansas City 127-114 and Portland 110-94 to remain at the top of the Central Division, nine games in front of Detroit. Dallas coach Dick Motta got his 700th career win, a 126-113 victory over the New Jersey Nets.

BOWLING—MIKE AULBY upset top-seeded Steve Cook 253-211 in the finale of the $235,000 PBA National Championship in Toledo.

BOXING—KHAOSAI GALAXY of Thailand KO'd South Korea's Lee Dong Hoon in the seventh round to retain his WBA junior bantamweight title, in Bangkok.

Milton McCrory of Detroit scored a 12-round unanimous decision over Pedro Vilella of New York to retain his WBC welterweight title, in Paris.

FIGURE SKATING—East Germany's KATARINA WITT, the U.S.S.R.'s ALEXANDR FADEEV, ELENA VALOVA and OLEG VASILIEF, and NATALIA BESTEMIANOVA and ANDREI BUKIN won the women's, men's, pairs and ice dancing events, respectively, at the world championships in Tokyo (page 64).

PRO FOOTBALL—Before Memphis's game against Baltimore, Showboat coach Pepper Rodgers summed up his team's condition in two words: "We're hurting." Running back Tim Spencer and wide receiver Henry Williams each had a bad ankle and defensive end Sam Clancy had a bum knee. Nevertheless, the Showboats beat the Stars 21-19, and that win, combined with Memphis's 24-14 victory over Jacksonville earlier in the week, gave the Showboats a 3-0 record and the Eastern Conference lead. When the Partridge family of Tustin, Calif. recalls the first L.A.-New Jersey game of 1985 it will be Rick, not Jeff, Partridge who smiles. Rick punts for the Generals, brother Jeff for the Express, and the Generals rallied to win 35-24 as Jersey's Doug Flutie ran eight, two and 11 yards for three TDs. Going into their Sunday afternoon matchup, both Houston and Oakland were undefeated. At the end of the 42-7 blowout only Houston was—and remained—the pacesetter in the Western Conference.

GOLF—FUZZY ZOELLER shot a four-under-par 67 to beat Tom Watson by two strokes and win the $500,000 Bay Hill Classic in Orlando, Fla. (page 62).

Bonnie Lauer defeated Alice Miller by five strokes to take the $330,000 LPGA Invitational in Costa Mesa, Calif. Lauer shot a seven-under-par 209 for the 6,085-yard course.

COLLEGE HOCKEY—Lowell advanced in Hockey East competition by splitting with New Hampshire 6-7, 8-4, then winning the mini-game 1-0. The Chiefs join Boston U (7-4, 4-2 victors over Maine), Boston College (a bye in the quarters) and the winner of the Northeastern-Providence quarterfinals in this week's semis. In the ECAC the four top-seeded teams—RPI, Harvard, Clarkson and Cornell—gained berths in the semis. Michigan State defeated Lake Superior State 5-1 in the CCHA finals, and Minnesota will meet Minnesota-Duluth in the WCHA finals.

PRO HOCKEY—Sure, the Smythe and league-leading Edmonton Oilers are the defending Stanley Cup champs. Sure, they've clinched a playoff berth. But they can't seem to win in OT. The Oilers, 0-1-8 in OT games this season, settled for another tie (3-3) against New York on Saturday despite outshooting the Rangers 44-25. The Great Ones then stopped Calgary 5-3 and lost to Vancouver 6-3. Montreal, the Adams Division leader, lost 4-3 to Minnesota, beat Winnipeg 4-2, and decisioned and tied Hartford 4-3 and 5-5 in OT. St. Louis, now eight points ahead of Chicago in the Norris, lost 4-1 to the North Stars but scored 7-2, 5-1 and 6-2 victories over Toronto, Pittsburgh and Detroit, respectively. And in the Patrick, Philly led Washington by two points as the Flyers won both ends of a home-and-home series against the Caps (page 24), then squashed Pittsburgh 11-4.

INDOOR SOCCER—Western Division-leading San Diego assured itself of a playoff berth with 8-5 wins over Dallas and Pittsburgh. In the latter game, midfielder Branko Segota had four goals—two in the fourth period—and one assist. Baltimore, still atop the Eastern Division, was stung by the Sting early in the week, 7-4, rebounded against Tacoma 7-4, then fell to Las Vegas 7-5.

TENNIS—HANA MANDLIKOVA defeated Catarina Lindqvist 6-3, 7-5 to win the $150,000 U.S. Women's Indoor championships in Princeton, N.J.

TRACK & FIELD—Three world indoor bests were set at the NCAA Nationals in Syracuse, N.Y. ESMERALDA GARCIA of Florida State twice bettered her one-week-old triple jump mark of 43'3½" with leaps of 43'7¼" and 44'4" (page 61); WILLIE CALDWELL of Baylor ran a 1:01.24 for 500 meters to take .02 off Mike Armour's previous best; and the Villanova relay team of KELLY TOOLE, DEBBIE GRANT, JOANNE KEHS and VERONICA McINTOSH clocked an 8:33.60 in the 3,200-meter relay, surpassing a Soviet National Team's 1972 record by eight seconds.

MILEPOSTS—ELECTED: To the Baseball Hall of Fame, ENOS (Country) SLAUGHTER, 68, and ARKY VAUGHAN, who died in 1952. Slaughter, an outfielder with the Cardinals, Yankees, A's and Braves, hit .300 over 19 seasons. Vaughan, who primarily played shortstop, had a .318 lifetime average in 14 seasons with the Pirates and the Dodgers.
