CANOEING—The U.S. won four of nine gold medals during slalom competition at the Wild Water World Championships in Bala, Wales, as STEPHEN and MICHAEL GARVIS won the C-2 men's event, ELIZABETH HAYMAN and FRITZ HALLER were victors in the C-2 mixed, and JON LUGBILL was the C-1 men's titlist. Lugbill then joined his brother RON and DAVID HEARN to win the C-1 team championship.

A nine-under-par 279 gave PAT BRADLEY a one-stroke victory over Beth Daniel in the $150,000 U.S. Women's Open in La Grange, Ill. (page 42).

HARNESS RACING—DEFIANT YANKEE ($6.40), Howard Beissinger in the sulky, beat Snack Bar by 1¾ lengths to win the $233,955 Dexter Cup Trot at Roosevelt Raceway. The 3-year-old covered the mile in 2:01.

Eugene Lefevre drove IDEAL DU GAZEAU ($11.40) to a neck's victory over Jorky in the $250,000 International Trot at Roosevelt Raceway. The 7-year-old horse covered the 1¼ miles in 2:32[3/5].

Galaxy Libra ($9), Bill Shoemaker up, beat Caterman by a neck to win the $226,050 Sunset Handicap at Hollywood Park. The 5-year-old ran the 1½ miles in 2:25[4/5].

MOTOR SPORTS—PANCHO CARTER drove his Penske PC-7 Cosworth at an average of 132.89 mph around the two-mile circuit of the Michigan International Speedway in Brooklyn to win the fire-marred Michigan 500. He finished two seconds ahead of Tony Bettenhausen Jr., who drove a McLaren Cosworth. A.J. Foyt fractured his right arm when his Coyote Cosworth crashed in the race's 80th lap.

Darrell Waltrip, in a Buick, won a 500-mile NASCAR Grand National event on the Pocono International Raceway in Long Pond, Pa. by one car length over Richard Petty, in a Buick. The winner averaged 119.110 mph around the 2.5-mile circuit.

SOCCER—NASL: He was once hailed as the greatest soccer player in the world, but Johan Cruyff, the striker who led Holland to the 1974 World Cup, hasn't had much opportunity to contribute to the Washington Diplomats' attack. The Dips have gone 3-7 since acquiring his services on June 17, and as they lost to Minnesota 3-1 last week to drop yet farther behind Eastern Division-leading New York, Cruyff, suffering from a lingering groin strain, watched from the stands. Meanwhile, the Cosmos had a Manic week, twice meeting—and narrowly beating—Montreal. Francois Van Der Elst and Giorgio Chinaglia scored shootout goals in a 5-4 win, and then Ivan (Beef) Buljan hit in overtime to give New York a 2-1 victory. For the sixth straight game, Chicago relied on an American to score its game-winner; the Sting padded its Central Division lead as a goal by Charlie Fajkus—who was born in Chicago to boot—triggered a 5-1 romp over Toronto. Most of the league's other top teams, however, were upset. In the South, first-place Atlanta lost 2-1 to last-place Jacksonville on Jean Pierre Tokoto's goal; the Northwest's leader, Vancouver, fell to middle-of-the-pack Calgary 3-2 when Franz Gerber scored with less than eight minutes left; and league cellar-dweller Dallas humbled Seattle, the newly crowned Trans-Atlantic Challenge Cup champ, 3-1 on two Wolfgang Rausch penalty kicks. Los Angeles and San Diego kept pace with each other in the West. The Aztecs beat Toronto 4-2 and San Jose 3-0, while the Sockers defeated Portland twice, 3-1 and 2-0.

ASL: Rochester's two first-string goalies gave the Flash a pair of 1-0 overtime shutouts and its third and fourth straight wins. Steve Jameson held Freedom Conference leader Carolina scoreless, while Eddie Azevedo scored Rochester's goal on Mike Lashchev's assist, and Jim Perriello shut out New England as Azevedo and Lashchev reversed roles. Pennsylvania ran its Liberty Conference-leading record to 13-2-4 by tying New York United 2-2 in overtime.

TENNIS—JOSE-LUIS CLERC won the U.S. Pro Championship in Brookline, Mass. with an 0-6, 6-3, 6-2 victory over Hans Gildemeister.

John Fitzgerald upset top-seeded Guillermo Vilas 3-6, 6-3, 7-5 to win a $75,000 tournament in Kitzbuehel, Austria.

Sylvia Hanika won a $150,000 tournament in Monte Carlo when Hana Mandlikova defaulted in the third set of their final match.

TRACK & FIELD—EVELYN ASHFORD ran the 100-yard dash in 10.90 seconds, lowering her two-year-old American women's record by .07 of a second, in Colorado Springs.

WEIGHTLIFTING—VAL BALISON, lifting in the 181¾-pound class, set an American record in the clean-and-jerk with a lift of 417¾ pounds at the National Sports Festival in Syracuse. It broke the mark of 416½ set by Curt White minutes earlier.

MILEPOSTS—ACQUITTED: By a federal jury in Los Angeles, JENNIFER L. KING, 35, on two counts of obstruction of justice. King, the attorney for former boxing promoter and racehorse owner Ross Fields (a/k/a Harold Smith), is still to be tried on two other charges connected with Fields' alleged involvement in the embezzlement of $21.3 million from Wells Fargo Bank.

BANNED: By The Athletics Congress from events it sanctions in the United States, Road Racers ALLISON ROE, 25, ANNE AUDAIN, 25, and LORRAINE MOLLER, 26, all of New Zealand; and DOMINGO TIBADUIZA, 31, of Colombia. The four participated in the Cascade Run-Off on June 28 in Portland, Ore., an event for which cash prizes were awarded to top finishers, a breach of TAC rules. TAC will hear the cases of 12 American participants, including such noted road racers as Cascade winner Greg Meyer, Bill Rogers, Herb Lindsay and Patti Catalano, in Chicago on Aug. 22.

GRANTED: To tennis star MARTINA NAVRATILOVA, 24, American citizenship in a-Los Angeles ceremony. The native Czech defected in 1975.

NAMED: To replace the late Jumbo Elliott as track coach at Villanova, CHARLES JENKINS, 47, a double champion—in the 400 meters and 4x400 relay—at the 1956 Olympics and the first of 28 Olympians coached by Elliott to a gold medal.

SIGNED: By the Colorado Rockies, free agent and former Boston Bruins Right Wing DWIGHT FOSTER, 24, to a multiyear contract. As compensation, the Rockies sent their 1982 entry draft second-round choice to Boston and gave the Bruins the option of exchanging first-round picks next year.

DIED: ROBERT H. STOUT, 55, the NCAA's all-around gymnastics titlist in 1952 and 1953 and a member of the 1952 U.S. Olympic team; of a heart attack; in Abington, Pa.
