A roundup of the sports information of the week

BOATING—JONATHAN WALES came back from a 10th-place finish in the first of seven races to win the International One-Design Championship at Marblehead, Mass. The 28-year-old Boston banker is one of the youngest helmsmen in the world championship one-design class.

James Hunt gambled on riding the current instead of the wind on the final spinnaker run and came from far behind to place second in the last of the eight-race series and win the Mallory Cup, symbol of the North American Sailing Championship, at Richmond, Calif. Going into the last race, Hunt led by a shaky one-quarter of a point, but his strong finish was worth seven points and he finished comfortably (48¾ to 43½) ahead of runner-up Richard Rose.

BOXING—Far ahead on points, world bantamweight champion LIONEL ROSE, the Australian aborigine, was caught by José Medel's strong left hook and knocked down in the seventh round of a 10-round nontitle bout in Los Angeles. But "all good fighters must be able to get off the floor and win," says Rose, and he did just that to gain a split decision.

Light-heavyweight champion BOB FOSTER also was on the floor and in serious trouble after being jolted by a right to the head from Eddie Vick in the first round of their nontitle fight in Albuquerque. The fight could have been a disaster for Foster, who had won the title from Dick Tiger in May. His legs quivered and he took a six-count gladly, but he came back to win, battering Vick throughout until the referee stopped the fight in the ninth round.

CYCLING—Qualifiers for the U.S. team at the Olympic trials at Encino, Calif. were: road races—BOB PARSONS, JIM VAN BOVEN, DAVID MOLKEY, JOHN ALLIS, MIKE PICKENS, JOHN HOWARD, DAN BUTLER, OLIVER MARTIN; tandem—JACK DISNEY, CHUCK PRANKE; 1,000-meter sprint—TIM MOUNTFORD; 4,000-meter team pursuit—SKIP CUTTING, JOHN VANDE VELDE, STEVE MAARANEN and WAYNE LE BOMBARD; 4,000-meter individual pursuit—DAVID BRINK.

GOLF—BRUCE FLEISHER, a 19-year-old from Hialeah, Fla., playing in his first national amateur championship, shot par golf on the final round to win the U.S. Amateur Championship in Columbus, Ohio despite a record-breaking final round of 65 by Marvin Giles III (page 20).

GYMNASTICS—Eight men, led by STEVE COHEN of Penn State, qualified for the U.S. Olympic team during trials in Los Angeles. Cohen, who ended with a total of 109.50 points, finished well ahead of DAVE THOR of Michigan State (107.90). The other six qualifiers were SID FREUDENSTEIN of California (107.55), FRED ROETHLISBERGER of Wisconsin (107.45), RICHARD LOYD of Northwestern State College of Louisiana (106.45), KANATI ALLEN of UCLA (106.10), JIM CULHANE of the New York Athletic Club (106.05) and 5'4½", 124-pound STEVE HUG, a high school junior from Chatsworth, Calif. (105.85).

HARNESS RACING—LAVERNE HANOVER won the $28,248 McMahon Memorial at the Du Quoin State Fair, in straight heats, for his 16th straight victory. The 2-year-old paced the fastest mile of the day, 1:59.4.

Nevele Pride trotted the mile in 1:56[3/5] in winning the second and final heat of the $34,737 Horseman Futurity at the Indiana State Fair in Indianapolis to set a new world record for 3-year-old trotters.

HORSE RACING—PROCESS SHOT, a 2-year-old filly owned by the former president of the New York Jets, Sonny Werblin, finished two lengths in front of Kahoolawe (a 16-to-1 long shot) to win the $187,500 Arlington-Washington Lassie Stakes at Arlington Park near Chicago. It was the sixth triumph in seven starts for Process Shot, who has already earned $133,504.

Stretchapoint, a 2-year-old maiden, finished six lengths in front in an Atlantic City claiming race and went unclaimed, but returned a track record of $230.80 for a $2 bet.

HORSE SHOWS—CAROL HOFMANN of North Branch, N.J., continuing her string of strong European performances, won the first international senior jumping event at the Rotterdam Horse Show and led the U.S. to the team title. Her winning time for the 18 jumps was 83.6 seconds, which was slightly more than 10 seconds faster than the second-place time turned in by Kathy Kusner of Monkton, Md.

SWIMMING—American women set seven new world records while competing in the U.S. Olympic Trials at Los Angeles. DEBBIE MEYER set three: 200-, 400-and 800-meter freestyle; CLAUDIA KOLB two: 200-and 400-meter individual medley; and CATIE BALL two: 100-and 200-meter breast-stroke.

TRACK & FIELD—Running in an Olympic intrasquad meet at South Lake Tahoe, Calif., VINCE MATTHEWS broke the world record for 400 meters, cutting one-tenth second off the mark of 44.5 set by Tommie Smith in 1967. Matthews did not realize he was running fast enough for a record, and neither did LEE EVANS, who ran a world-record 1:14.3 for 600 meters. Larry James (1:14.6), Mark Winzeried (1:14.8) and Ron Freeman (1:15.9) were also under the old record of 1:16.5, set a month ago by Tom Farrell. Mel Pender ran a 10-flat 100 meters, and John Carlos and Clyde Glosson each ran 20.1 in separate heats of the 200. Jack Bachelor was reported to have run a startling 13:33.7 for 5,000 meters, but the race proved to have been a lap short.

MILEPOSTS—SETTLED: by Superior Court Judge Walter Carpeneti, the legal controversy between the American Basketball Association's Oakland Oaks and the National Basketball Association's San Francisco Warriors, which threatened to keep superscorer RICK BARRY off the pro basketball court indefinitely, in San Francisco. Barry, who took NBA scoring honors away from Wilt Chamberlain in 1966-67, jumped from the Warriors to the Oaks after that season but was prevented from playing in 1967-68 because he was still legally under contract to the Warriors. He sat out his option last year, but the Warriors contended that Barry had to play out his option before he could switch to Oakland. The judge disagreed, freeing Barry to play with Oakland this season, but did concede that a damage claim by the Warriors against Barry and the Oaks appeared valid.

HIRED: By the San Diego Padres, PRESTON GOMEZ, 45, a Dodger coach whose major league playing experience amounted to eight games with Washington in 1944, to manage the new National League expansion team.

REHIRED—LARRY SHEPARD, as manager of the Pittsburgh Pirates, despite a resoundingly disappointing year by the injury-riddled Pirates in Shepard's first season in the job.

RESIGNED: Professional Golfers' Association Tournament Director JACK TUTHILL, after the PGA had done away with his job by abolishing the tournament committee.

TRADED: By the Detroit Lions, Safety BRUCE MAHER to the New York Giants in return for Linebacker BILL SWAIN and Running Back BILL TRIPLETT.

DIED: PETE BARRY, 71, a member of the original Celtics, whose playing career lasted over 21 years and spanned several eras in basketball's evolution; in New York City of a heart attack. Barry was the complete player, a six-footer who could shoot, rebound and set up plays. During his time with the team the Celtics dominated basketball.
