A roundup of the week Oct. 3-9

BASEBALL—OAKLAND, behind the three-hit pitching of John (Blue Moon) Odom, took a 2-0 lead in the American League playoffs by defeating Detroit 5-0. In the first game the A's came from behind in the 11th inning for a 3-2 victory over the Tigers, who won the East Division title in a year-end showdown series with the Boston Red Sox. The National League playoff was tied at a game apiece as PITTSBURGH won the opening game 5-1 and CINCINNATI the second 5-3 (page 28).

PRO FOOTBALL—AFC: MIAMI took a two-game lead in the Eastern Division with a 27-17 victory over the sputtering New York Jets. Bob Griese completed 15 of 27 passes for 220 yards and one touchdown, Larry Csonka rushed for 102 yards and Jim Kiick scored twice as the Dolphins, pro football's only undefeated team, let the Jets have it from all sides. Baltimore, no longer invincible at home, gave one away to SAN DIEGO 23-20. The Colts led 20-10 in the fourth quarter and even intercepted two passes in the period, but they also fumbled three times and the Chargers turned all three into scores. The tying and winning points came on Dennis Partee field goals—one from 40 yards with 2:14 remaining and another from 27 yards with four seconds to play. Mike Garrett gained 132 yards and scored the winner's two touchdowns. BUFFALO struck for 28 points in the second quarter and beat New England 38-14. CINCINNATI rookie Tommy Casanova set up the Bengals' first touchdown in nine quarters with a 37-yard punt return and later added one of 66 yards for a score in a 21-10 triumph over Denver. KANSAS CITY forced Cleveland into seven first-half turnovers and humbled the Browns 31-7. Quarterback Mike Livingston, who has not lost in 11 starts for the Chiefs, gave Len Dawson a rest and threw three touchdown passes for the second consecutive week.

NFC: WASHINGTON played a scoreless first half at home against Philadelphia before a short run by Larry Brown and a 36-yard pass from Sonny Jurgensen to Roy Jefferson put the winless Eagles away 14-0. DALLAS would not have kept pace with the Redskins if Pittsburgh's Terry Bradshaw hadn't overthrown a receiver open in the end zone on the last play of the game. The final score was 17-13 in favor of the Cowboys and Calvin Hill was the game's hero. He gained 135 yards, scored a touchdown and threw 55 yards to Ron Sellers for the winning points. For a while, anyway, the NEW YORK GIANTS and ST. LOUIS are within reach of the Eastern Division lead. The Giants stomped on Philadelphia 27-12 Monday night on four touchdowns by Ron Johnson, and then came home to annihilate New Orleans 45-21 on three more by Fullback Charlie Evans and three scoring passes from Norm Snead. The Cardinals' Gary Cuozzo, who used to be pro football's No. 1 backup quarterback behind Joe Kapp, returned to Minnesota and beat Fran Tarkenton and the Vikings 19-17 when Fred Cox missed a last-second field goal. DETROIT'S final drive of the day nipped Atlanta 26-23 as Steve Owens scored his second touchdown with 34 seconds left in the game. GREEN BAY remained in a tie with the Lions on the strength of rookie Chester Marcol's 37-yard field goal that beat Chicago 20-17 in the last half minute. LOS ANGELES Quarterback Roman Gabriel tossed a pair of long touchdown passes to Jack Snow in a 31-7 upset of San Francisco.

GOLF—GAY BREWER parred the fourth extra hole of the $300,000 Pacific Masters tournament in Chiba, Japan, thereby winning a playoff with Australia's David Graham and $65,000—the richest first prize in history (page 36).

HARNESS RACING—SUPER BOWL ($2.20 and $2.40), driven by Stanley Dancer, became the sixth winner of trotting's triple crown by winning two straight heats of the $56,210 Kentucky Futurity in Lexington despite tire blowouts in each heat.

Eddy Jeff ($4), driven by Ed Lohmeyer Jr., scored his seventh consecutive pacing triumph, winning by 3½ lengths over Sharp Frenchy in the $110,000 New York Sires Stakes for 2-year-old colts and geldings at Yonkers Raceway.

HOCKEY—In an NHL debut for both teams, the ATLANTA Flames defeated the New York Islanders 3-2 on a pair of goals by Ray Comeau and Bob Leiter within 1:05 of the third period. BUFFALO handed the Flames their first loss the next night 5-3 as Gil Perreault, who quit Team Canada in Moscow to come home and get in shape, got an assist and a goal in the final period. MONTREAL Goalie Ken Dryden, himself a hero of Team Canada's series victory over the Soviet Union, went right out and turned aside 33 Minnesota shots in a 3-0 shutout. DETROIT hit the New York Rangers with four goals in the first period and coasted to a 5-3 win. Third-period goals by Ken Schinkel and Al McDonough lifted PITTSBURGH to a 4-2 victory over Los Angeles, but the Kings bounced back to defeat Boston 4-2. ST. LOUIS blew a 3-1 lead and needed Jack Egers' second goal of the game to salvage a 4-4 tie with PHILADELPHIA. Playing with six rookies in the lineup and its new coach, Vic Stasiuk, on the bench, VANCOUVER edged California 3-2. CHICAGO handed the Rangers a second defeat 5-1.

HORSE RACING—SAN SAN, a 19-to-1 shot ridden by Jockey Freddy Head, won the $448,000 Prix de l'Arc de Triomphe in Paris by 1½ lengths over Rescousse and Homeric, as favored Hard to Beat and Roberto finished far back (page 108).

La Prevoyante ($2.60), ridden by John LeBlanc, clinched the 2-year-old-filly championship with her 10th straight victory, by two lengths in the $114,100 Frizette Stakes at Belmont Park.

MOTOR SPORTS—JACKIE STEWART of Scotland led all the way from the pole position to win the U.S. Grand Prix in Watkins Glen, N.Y., the last race in the circuit's 12-race series. Stewart's victory over Fran√ßois Cevert of France and Denis Hulme of New Zealand gave him second place behind Emerson Fittipaldi of Brazil in the world drivers' championship (page 32).

Bobby Allison, the leading NASCAR driver of the year with $218,200, won his ninth race in a Chevrolet, beating Buddy Baker's Dodge by a car length in the $123,000, 500-mile Grand National in Charlotte, N.C.

TENNIS—KEN ROSEWALL, 37, of Australia, took no special notice of countryman Fred Stolle's 34th birthday, beating him 7-5, 6-3, 6-3 in the singles final of the $33,222 Tokyo World Championship Tennis tournament.

SIGNED: To a six-year contract with the Golden State Warriors worth $1.4 million, RICK BARRY, 28, pro basketball's traveling superstar and the only man to lead both the NBA and ABA in scoring. In doing so, Barry cut all future ties with the New York Nets, for whom he starred the last two years.

DESTROYED: DETERMINE, the first gray to win the Kentucky Derby (1954) and sire of Decidedly, the second gray to win it (1962).
