FOOTBALL—NFL: The week's big game was in the Coastal Division of the Western Conference where LOS ANGELES upset Baltimore 27-20 after a scramble in which the lead changed hands three times and the score was tied twice (page 16). ATLANTA beat San Francisco for the first time in their six meetings, 24-12, as the sharp Falcon defense surprised Quarterback John Brodie with three interceptions. At Yankee Stadium, with five minutes to go, favored Minnesota seemed to have things sewed up with a 13-point lead, but NEW YORK's Fran Tarkenton, taking advantage of a fortuitous fumble, threw touchdown passes of 16 and 10 yards to rookie End Don Herrmann for a 24-23 victory, and new Giant Head Coach Alex Webster left the field to a standing ovation. Detroit's five-point lead Over the Steelers also looked safe until, with three minutes to play, PITTSBURGH Quarterback Dick Shiner threw four passes for 49 yards to set up a six-yard score by rookie Running back Warren Bankston and a 16-13 Steeler win. Despite harassment by a St. Louis defense that threw him for losses five times, rookie DALLAS Quarterback Roger Staubach got off a 75-yard scoring pass to Lance Rentzel in the first period and scored from the three-yard line in the fourth. Another Cowboy rookie, Running Back Calvin Hill, broke the close game open in the third quarter with a 53-yard scoring pass, also to Rentzel. Mike Clark added a field goal and the Cowboys won 24-3. GREEN BAY shut out Chicago 17-0 in their 101st meeting by confining Gale Sayers to 36 yards in 10 carries, intercepting two Bear passes and blocking a last-minute field-goal attempt. Eastern Conference champion CLEVELAND lost star ground-gainer Leroy Kelly in the first quarter because of a pulled hamstring but was carried ably by rookie Ron Johnson (118 yards on 17 carries, two TDs) and Reece Morrison (48 yards on 16 carries) to a 27-20 win over Philadelphia. Three scoring passes by Sonny Jurgensen for WASHINGTON overshadowed a good New Orleans ground game and the Redskins beat the Saints 26-20.
AFL: There were surprises on the junior circuit, too. A two-point conversion attempt that failed was the difference in DENVER's (2-0) 21-19 upset of New York (1-1). Pete Liske, playing for injured Bronco Quarterback Steve Tensi, threw for two scores and Floyd Little gained 104 yards against the world champions. A 98-yard punt by Jet Steve O'Neal set a new pro distance record. Prize rookie Greg Cook of CINCINNATI (2-0), ignoring the odds, threw for three scores and ran for a fourth as the Bengals whipped favored San Diego (0-2) 34-20. Cook even scored once for the Chargers—fumbling in his own end zone while trying to pass. OAKLAND (2-0) defeated Miami (0-2) 20-17 when George Blanda kicked a 46-yard field goal with 11 seconds remaining. A fine HOUSTON (1-1) defense dumped Buffalo (0-2) Quarterback Jack Kemp six times for a loss of 59 yards and picked off three of his passes while holding O.J. Simpson to 58 yards. Pete Beathard's passing (10 completions for 140 yards and one TD) gave the Oilers their 17-3 win over the Bills. Veteran Len Dawson and Mike Garrett combined their talents for 18 points as KANSAS CITY (2-0) smashed Boston (0-2) 31-0.

On the 2.5-mile Mosport Park course in Bowmanville, Ont., Stewart led the 20-car field until the 32nd lap, when he was forced out of contention as Ickx passed him on the inside on a 140-mph gravel corner.
