A roundup of the week Feb. 24-March 2

PRO BASKETBALL—NBA: Going into the week the Washington Bullets had the best rebounder in the league in Wes Unseld (14.6 average) and the best record (47-17). The latter may be in jeopardy because of a finger Unseld broke in a 106-95 victory over Detroit that will keep him out for two weeks. Houston, runner-up to Washington in the Central, kept Cleveland in third place with a 3-1 week, which included a 114—87 victory over the Cavaliers. New Orleans got 38 points and 11 assists from Pete Maravich in a defeat of the Rockets that extended the Jazz' win streak to six before Midwest leader Chicago halted it. The Bulls also gored Atlanta and had a 4½-game lead over Kansas City-Omaha. The Kings' lone triumph came against Milwaukee, which had a victory over Buffalo. The New York Knicks scalped the Braves, too, but lost the next night to last-place Philadelphia in a fight for a wild-card playoff spot. Boston hiked its Atlantic lead to 5½ games with a 3-0 week. Phoenix upset Pacific leader Golden State twice by a total of 20 points and went on to a 4-0 week. Seattle hung on to a half-game lead over the Suns, thanks to a lone win over the Knicks. Portland beat the Lakers in double overtime and bombed the 76ers 99-77.

ABA: The largest crowd of the season, 16,188, jammed Kentucky's Freedom Hall to watch the Colonels beat New York 95-84 and gain a share of the Eastern Division lead with the Nets (page 20). Arenas were not nearly as crowded in the West where Denver reigns. The Nuggets had a two-point win over Kentucky and handed New York its worst defeat of the season, 148-114, before 7,622 fans, the biggest Denver crowd this year. Indiana managed to outpace the Nuggets 124-109 but Denver still held a 9½-game lead over San Antonio. Earlier the Pacers beat San Diego 120-108 as George McGinnis amassed 41 points, 25 rebounds and a career-high 13 assists. Ownership of the San Diego franchise was assumed by the league because of the Qs' financial problems. Willie Wise scored 30 points in his debut as a Squire, but Virginia still lost to St. Louis 111-100. Earlier, the Spirits had fallen to Memphis 114-107. The Utah Stars had but one win, a sweet one against the defending champion Nets.

BOWLING—NELSON BURTON JR. of St. Louis earned $14,000 by beating Eddie Ressler 208-194 in the finals of the $100,000 Midas Open at Bradley Bowl in Windsor Locks, Conn.

BOXING—GUTS ISHIMATSU of Japan, the WBC lightweight champion, scored a unanimous 15-round decision over Ken Buchanan of Scotland, in Tokyo.

Joe Bugner of Great Britain retained his European heavyweight title with a fifth-round technical knockout of Italy's Dante Cané in Bologna.

Panama's ROBERTO DURAN retained the WBA lightweight crown with a 14th-round knockout of Ray Lampkin of the U.S., in Panama City, Panama.

GOLF—BOB MURPHY fired a final-round 68 for a 273, earning $52,000 and a one-stroke victory over Eddie Pearce in the Jackie Gleason-Inverrary Classic at Lauderhill, Fla.

HOCKEY—NHL: Vancouver had paced the Smythe practically all season but an 0-3 week coupled with a 3-0 mark for Chicago vaulted the Black Hawks into a one-point division lead. The Hawks sandwiched a 6-2 defeat of Washington between a pair of triumphs over Atlanta, one of which gave Goalie Tony Esposito his fifth shutout of the season. The Canucks meanwhile lost to Norris and Patrick leaders Montreal (4-3) and Philadelphia (3-1), and were blasted 7-3 by Pittsburgh. Buffalo, sitting pretty in the Adams, ran its unbeaten streak to 12 games with a 5-0 stampeding of Los Angeles. The Kings started out the week tying the Seals 2-2 and finished it with a 7-4 victory over Minnesota, which also had beaten the Seals. The New York Islanders blanked St. Louis 3-0 and defeated California, too, 6-1. The Blues managed a last-minute goal against the New York Rangers' Eddie Giacomin but fell 5-1 as the Rangers continued their pursuit of Philadelphia, which they beat 2-1. Toronto had a 3-1 week, outshining the North Stars 9-2 before beating Kansas City 4-2. Boston had a nine-goal game also, bombing Detroit 9-4 while the Red Wings beat the Penguins 3-1 and the Sabres 3-2.

WHA: "It was like a midget game," said Houston goaltender Wayne Rutledge. "Wherever the puck was, six guys were there. It was a scramble all night." Nevertheless, Rutledge let only one shot get by him as the West-leading Aeros beat Toronto 5-1 for the first of its four victories. The Toros, second in the Canadian, managed a 6-4 win against San Diego while Canadian leader Quebec sank the Mariners twice and outskated Vancouver 9-7. The Blazers also were cooled by East front-runner New England, which went 3-1-1 for the week and had a 15-point lead in the division. Toronto made big news off the ice when Owner John Bassett Jr. reportedly signed 18-year-old Mark Napier to a three-year contract, violating an unwritten rule that said neither pro league would sign any player under 20 before a formal draft. Meanwhile, Winnipeg's Bobby Hull scored his 55th goal of the season in a win over San Diego. The Mariners, Cleveland, Baltimore and Vancouver failed to win during the week but the Phoenix Roadrunners won big, 12-2, against Indianapolis. Chicago had a five-game victory streak snapped by the Aeros in a 3-1 week (page 60) while Minnesota went 2-2-1. The Edmonton Oilers beat the Fighting Saints 6-4 and handed Baltimore yet another loss.
