BASKETBALL—NBA: For the first few weeks of the season, PHILADELPHIA's (11-1) Wilt Chamberlain contentedly fed Guards Larry Costello and Hal Greer while he concentrated on other matters. Last week, however, Wilt started shooting once again (he averaged 26 points) as the 76ers won four in a row and gained a one-game lead over BOSTON (10-2) in the East. The Celtics won three games to extend their winning streak to six but then lost to the Hawks 115-98 and slipped from a tie for first into second. NEW YORK (8-6), in third, split four games, while CINCINNATI (5-7) lost two of three, and BALTIMORE (2-13) dropped three of four. In the West, Rick Barry, the NBA scoring leader, tossed in 127 points as SAN FRANCISCO (9-6) won three and climbed into first, a game ahead of ST. LOUIS (6-5), winner of two games. DETROIT (6-8) lost three of four, while CHICAGO (7-10), the leader at the beginning of the week, dropped four in a row and plunged to fourth place. LOS ANGELES (4-10) broke a three-game losing streak by beating the Pistons 144-88 as Jerry West scored 35 points.
FOOTBALL—NFL: PITTSBURGH (3-5-1), going no place but suddenly having a lot of fun, beat first-place St. Louis (7-2-1) 30-9, just one week after upsetting the Browns. The Cardinal loss was assured when the Steelers intercepted three passes in the third period off Terry Nofsinger, subbing for the injured Charley Johnson, and turned two of them into touchdowns. DALLAS (6-2-1) moved to within half a game of the Cards in the East by defeating Washington (5-5) 31-30 on Danny Villanueva's 20-yard field goal with 15 seconds left, while CLEVELAND (6-3), only a game out, defeated Philadelphia (5-5) 27-7. In the West, BALTIMORE (7-2) beat an aroused Atlanta (0-9) 19-7 after trailing 7-6 at half time and tied idle GREEN BAY (7-2) for the lead. SAN FRANCISCO (4-3-2) tied CHICAGO (3-4-2) 30-30 when Tommy Davis booted a 44-yard field goal with 9 seconds to go; Garo Yepremian, a native of Cyprus who saw his first football game only five weeks ago, kicked six field goals, an NFL record, as DETROIT (3-6-1) upset Minnesota (3-5-1) 32-31; and LOS ANGELES (5-5) romped over New York (1-7-1) 55-14. The Rams also set an NFL mark by making 38 first downs.
AFL: New York (4-4-1) lost its fourth game in a row when first-place BUFFALO (6-3-1) contained Joe Namath and defeated the Jets 14-3, knocking them into third place in the East. Gino Cappelletti, the scoring champion four times in the six-year history of the AFL, picked up 21 points (on two TD passes, two field goals and three conversions) to take the lead again this season as BOSTON (5-3-1), half a game behind the Bills, beat Houston (3-7) 27-21. In the Western Division, KANSAS CITY (8-2) stretched its lead to two games by defeating Miami (2-7) 34-16 on Len Dawson's three touchdown passes, while OAKLAND (6-4) slipped past San Diego (5-4-1) into second place with a 41-19 victory over the Chargers.
GOLF—The U.S. pair of Jack Nicklaus and Arnold Palmer won the Canada Cup team title in Tokyo, but individual honors went to Canada's GEORGE KNUDSON, who defeated Hideyo Sugimoto of Japan in a sudden-death playoff (page 67).
HARNESS RACING—BILLY HAUGHTON drove CARLISLE ($5.40) to a three-length victory over Armbro Gazelle in the $87,100 Dexter Cup at Roosevelt Raceway and the next night guided SMOKEOVER ($22) to a three-length win over Senator Burton in the $60,000 Atlantic Seabord Pacing Championship at Suffolk Downs. The two victories were worth $73,590 and raised Haughton's season purse total to $1,016,806, making him the third driver in harness-racing history to pass the $1 million mark. The first was Stanley Dancer, who did it twice (1964 and this season), and the second was George Sholty, who drove Polaris to third place in the Dexter Cup and boosted his 1966 total to $1,002,778.
HOCKEY—NHL: CHICAGO (7-2-0) moved two points ahead in the tight NHL race by winning two of three. The Bruins broke TORONTO's (3-3-6) seven-game unbeaten streak with a 4-0 victory, but the Maple Leafs beat the Canadiens and tied the Red Wings to hold second place. After losing one and tying one, NEW YORK (4-5-3) climbed into third with two straight wins as Boom Boom Geoffrion scored a goal and assisted on six others. BOSTON (4-5-2) also moved up—from the cellar to a share of fourth place with the Red Wings—by winning two and tying one as DETROIT (4-6-2) had a 1-1-1 week. MONTREAL (4-5-1), on the other hand, fell all the way from a tie for second into the cellar with three losses in a row.
HORSE RACING—The French 3-year-old colt BEHISTOUN ($34), won the Washington, D.C. International by 2� lengths and Wheatley Stable's 2-year-old colt SUCCESSOR ($6.60) took the Garden State Stakes by three lengths (page 28).
