A roundup of the week Feb. 20-26

PRO BASKETBALL—All that Jazz jive has begun to quiet down now that Utah has begun to cool down. The Midwest Division-leading Jazz, 7-8 since the All-Star break, was only three games ahead of Dallas following the Mavericks' 97-95 win in Salt Lake City. The Mavs' Rolando Blackman scored the decisive tip-in with :01 left. Utah earlier beat San Antonio 143-142 in double OT—but worse than the defeat for the Spurs were the two fractured cheekbones center Artis Gilmore suffered. He'll be out at least four weeks. Milwaukee clung to a one-game Central Division lead over Detroit by winning twice, including a 130-119 victory over San Antonio in which the Bucks tied the club record for field-goal percentage by making 65.8% of their shots. Portland had the good fortune to make an Eastern road trip when its hosts were slumping. The Trail Blazers beat the 76ers 119-114 in Philadelphia and the Knicks 106-89 in New York. Overall, Philly and New York lost four games apiece. The Atlantic Division leader, Boston, lost twice; one of the defeats was at the hands of Pacific Division-leading Los Angeles (page 12).

BOXING—MICHAEL SPINKS retained the world light heavyweight title with a 12-round unanimous decision over Eddie Davis in Atlantic City.

BOWLING—RICKIE SAJEK defeated Gary Skidmore 246-243 to win a $125,000 PBA tournament in North Olmsted, Ohio.

PRO FOOTBALL—The USFL looked glossy in Florida but drossy in other places. Jacksonville debuted with a 53-14 rout of Washington. Bulls quarterback Matt Robinson threw for 299 yards and three touchdowns before 49,392 Gator Bowl fans. Gary Anderson had 214 all-purpose yards and two TDs to lead Tampa Bay past Houston 20-17 as 42,915 looked on at Tampa Stadium. Crowds of less than 20,000 watched New Orleans beat San Antonio 13-10 and Oklahoma defeat Pittsburgh 7-3. Arizona walloped Oakland 35-7. Philadelphia beat Memphis 17-9, Denver ripped Los Angeles 27-10 and New Jersey took care of Birmingham 17-6 (page 16).

HOCKEY—Minnesota, the Norris Division leader, played the good teams well and the bad teams badly. Neal Broten's two goals lifted the North Stars into a 3-3 tie with Philadelphia, and Mark Napier's two scores and one assist paced them past Adams Division-leading Buffalo 5-1 but not before Minnesota lost 3-2 to Los Angeles and 5-2 to Detroit. The Sabres beat the Flyers 5-4 in overtime in Philadelphia. The Flyers stayed close in the tight Patrick Division race on Sunday when they won, 5-3, over the first-place Islanders, who led the Rangers by two points and the Capitals and Flyers by four. Wayne Gretzky of Smythe Division-leading Edmonton had four-goal games on successive nights in defeats of St. Louis and Pittsburgh but against Calgary he was shut out for only the second time this season. The Oilers won anyway, 5-3, and made it seven wins in a row the next night with an 8-3 rout of Toronto.

MOTOR SPORTS—BRIAN REDMAN and DOC BUNDY, in a Jaguar XJR-5, won the three-hour Grand Prix of Miami by 1:21.3 over Bob Tullius and Pat Bedard, also in a Jag. The winners averaged 72.623 mph on a 1.85-mile course through the streets of Miami.

INDOOR SOCCER—MISL: Kansas City remained percentage points ahead of St. Louis in the West. Both teams lost twice, the Steamers 8-2 at Los Angeles and 7-5 at Phoenix, while K.C. fell to Eastern stalwarts Pittsburgh (8-5) and first-place Cleveland (6-5). Financially strapped New York traded Fred Grgurev, tied for the league scoring lead, and his hefty contract to Memphis.
