A roundup of the sports information of the week

BOATING—GRAHAM HALL of Bayside, N.Y. won the Mallory Cup, North America's men's sailing championship. Hall, in second place prior to the final race, was an easy victor when 18-year-old Peter Warren finished fourth behind him and slipped to second in the overall standings (page 57).

FOOTBALL—Obviously intent upon being Chiefs again in deed as well as nickname, KANSAS CITY continued its exhibition exploits with a fifth consecutive win, over St. Louis 31-21. Len Dawson threw for a pair of scores, and the Chiefs' defense held the Cardinals scoreless in the second and third quarters. OAKLAND, on the contrary, won its first preseason game in four starts 24-6 over the New York Jets. Joe Namath played only long enough to complete five of seven passes and then relaxed on the bench, more as a safety precaution against the savage rushes of Ben Davidson and Ike Lassiter than to rest his sore knees. The Raiders' 41-year-old double-threat quarterback, George Blanda, put the game out of reach in the fourth period with a 23-yard touchdown pass and a field goal. With Namath going nearly full time later in the week, NEW YORK beat Minnesota 24-21. In Montreal's Jarry Park, where the baseball Expos draw well, only 8,212 people showed up to see DETROIT Halfback Mel Farr score the only touchdown in a 22-9 victory over Boston. Lion Placekicker Errol Mann outbooted the Patriots' Gino Capelletti five field goals to three. Detroit made it two wins in one week, slipping by Washington 21-20 as Lem Barney returned a blocked field goal 77 yards for a score after his 91-yard punt runback was nullified. Craig Morton continued to help DALLAS forget Don Meredith's retirement with a 34-yard scoring pass to Lance Rentzel and another of the same length to Bob Hayes, which set up the touchdown that beat Houston 14-11 before 55,310 in the Astrodome (page 18). PHILADELPHIA refused to be pinned by the New York Giants, rallying from a 14-point deficit to win 24-17. BALTIMORE stayed with Kansas City in the unbeaten ranks, winning its fifth game in a row 23-10 at the expense of Miami. Johnny Unitas was the Colt protagonist, making up for an early interception with a touchdown pass to Jimmy Orr. Unitas led a 98-yard march for a second score, and Lou Michaels' toe accounted for three field goals. Mac Percival kicked five field goals in a 23-16 CHICAGO victory over Buffalo in the first game of a doubleheader at Cleveland that drew 85,532 fans. Bubba Thornton returned a kickoff 97 yards for the Bills, and O.J. Simpson caught a pair of passes. In the second game of the twin bill GREEN BAY rallied from an early 14-0 deficit to beat Cleveland and even its exhibition record. Rookie Greg Cook continued to please Coach Paul Brown by tossing a touchdown pass and setting up three field goals as CINCINNATI trimmed Pittsburgh 23-13. Another first-year man, Quarterback Edd Hargett, had a big night for NEW ORLEANS when he threw for two touchdowns in the final 6½ minutes to salvage a 21-17 victory over Atlanta. In an unneighborly Southern California fight, LOS ANGELES beat San Diego 24-14.

GOLF—STEVE MELNYK, a senior at the University of Florida, led from start to finish in the 69th U.S. Amateur Championship in Oakmont, Pa. Exploding from a bunker for an eagle on the 58th hole, Melnyk came home with a 70 for a 72-hole total of 286, two over par (page 26). Vinnie Giles became the first man in the tourney's history to finish second three times.

HARNESS RACING—Favored LINDY'S PRIDE won the 44th Hambletonian in Du Quoin, Ill. in straight one-mile heats. The 3-year-old trotter earned $62,455 with his 20th victory in 37 starts (page 60).

Canada's FRESH YANKEE ($17.60) closed with a rush to overhaul France's champion mare Une de Mai in the $40,000 Challenge Cup at Roosevelt Raceway. Fresh Yankee, who had finished third behind Une de Mai and America's Nevele Pride in the $100,000 Roosevelt International, won the trot by a head. Nevele Pride was scratched.

HORSE RACING—FAST HILARIOUS ($13.60) held off a charging Night Invader by a neck in the $100,000 American Derby at Arlington Park. More than 30,000 people attended Thoroughbred racing's first major stakes event run at night.

King Ranch's GALLANT BLOOM ($5) won the 74th running of the Gazelle at Belmont Park and tied the stakes record of 1:49 for 1‚⅛ miles. In winning her eighth straight race Gallant Bloom carried more weight successfully (127 pounds) than any other filly since the race was restricted to 3-year-olds.

SOCCER—The KANSAS CITY Spurs clinched the North American Soccer League championship by defeating the Baltimore Bays 2-0, giving Kansas City 110 points for the season and putting the Spurs beyond reach of second-place Atlanta.

TENNIS—U.S. Davis Cup aspirations received a jolt when four players from the five-member team that will meet Rumania in a few weeks were knocked out in early rounds of the U.S. Open at Forest Hills. Bob Lutz was beaten the first day by third-seeded professional Tony Roche of Australia 9-11, 6-4, 6-4, 9-7. Stan Smith, Charlie Pasarell and Clark Graebner lost in the second round. Smith was toppled by Rumania's Ilie Nastase 5-7, 12-10, 7-5, 6-3, Pasarell fell in straight sets to Aussie Terry Addison 6-3, 9-7, 6-4 and Graebner had to default to British pro Roger Taylor when he sprained an ankle. Fourth-seeded Arthur Ashe, the fifth Davis Cup player and winner of Forest Hills' first pro-am tournament last year, stayed in by powering through two easy matches with his new "rug beater" racket. Top-seeded ROD LAVER of Australia moved into the fourth round untested. Biggest upset among the pros came when last year's Open runner-up, Tom Okker, lost to British amateur Mark Cox in the first round 7-9, 6-3, 0-6, 6-4, 9-7.

MILEPOSTS—SIGNED: By the Philadelphia Eagles, Purdue All-America LEROY KEYES, pro football's longest big-name rookie holdout, to a three-year contract reported to be worth about $200,000. Eagles General Manager Pete Retzlaff said Keyes will be getting more per year than Buffalo's O.J. Simpson, the man who beat him out for the Heisman Trophy last season.

HIRED: As general manager of the NBA's Chicago Bulls, PAT WILLIAMS, former promotion manager of the Philadelphia 76ers. Williams replaced Dick Klein, who created the franchise but had trouble getting along with coaches and signing draft choices.

REUNITED: With the San Francisco Warriors of the National Basketball Association, RICK BARRY, the slender forward who was NBA Rookie of the Year in 1965 and leading scorer in 1966 before jumping to the ABA's Oakland Oaks. Barry signed a five-year contract with the Warriors, saying he did not want to move to Washington with the recently sold Oakland franchise.

WOUNDED: Former Notre Dame Captain and Pittsburgh Steeler Halfback ROCKY BLEIER, in the left side and right hip, leg and foot by Viet Cong sniper fire and a grenade. Army Private Bleier underwent an operation in Tokyo, and his football career may be over. However, Steeler Owner Art Rooney received a letter from Bleier saying he would be able to play again.
