A Roundup Of The Week Sept. 14-20

BOXING—SUGAR RAY LEONARD won the undisputed world welterweight championship with a 14th-round TKO of Thomas Hearns in Las Vegas (page 18).

PRO FOOTBALL—Six of the teams that were winless going into the week's action came away with victories. The St. Louis Cardinals, with 37-year-old Quarterback Jim Hart back at the controls, beat Washington 40-30. Hart threw for three TDs, and his 226 yards passing moved him into fourth on the alltime list. His performance also overshadowed that of the losers' Joe Theismann, who threw for four touchdowns and 388 yards. Other first-time winners were Pittsburgh, which beat the winless Jets 38-10 as rookie Running Back Frank Pollard ran for two TDs; Minnesota, which defeated Detroit 26-24 on Rich Danmeier's 20-yard field goal with four seconds to go; Cleveland, a 20-17 victor over Cincinnati; Chicago, which upended Tampa Bay 28-17; and the Rams, with Wendell Tyler rushing for 108 yards and two TDs, who beat Green Bay 35-23. Unbeaten Miami sacked Houston's Ken Stabler eight times in a 16-10 win, and Atlanta won its third straight—the Falcons are off to their best start ever—by defeating San Francisco 34-17, as Steve Bartkowski threw three TD passes despite a cracked rib and Tom Pridemore returned an interception 101 yards for a score. San Diego beat Kansas City 42-31 in a meeting of the AFC West's two undefeated teams (page 40). Elsewhere, the Giants downed New Orleans 20-7, Denver defeated Baltimore 28-10 and Oakland beat Seattle 20-10 for its second win of the week. Last season's Super Bowl teams won night games early in the week, the Raiders routing Minnesota 36-10 and Philadelphia defeating Buffalo 20-14.

ROAD RACING—HERB LINDSAY of Boulder, Colo., set two American records at the Maple Leaf Half-Marathon in Manchester, Vt. His time of 1:01:47 for the 13.1 miles lowered by 29 seconds the old mark set by Stan Mavis in January, 1980, and en route he also broke Greg Meyer's two-week-old 20-kilometer record of 59:08, with a clocking of 58:37.

SOCCER—NASL: For the fourth time in five years the Cosmos will be in the Soccer Bowl, and for the fourth time in six seasons their star forward, Giorgio Chinaglia, is the league's scoring champion. But it wasn't until last week, on the day before his three goals helped beat Fort Lauderdale 4-1 to put the Cosmos in the league championship game in Toronto on Sept. 26, that Chinaglia won his first NASL Most Valuable Player Award. Chicago scored a breakthrough, too, solving San Diego Goalkeeper Volkmar Gross for only the second time in seven postseason games this season and tying their semifinal series at one game each. Karl-Heinz Granitza scored both Sting goals in the 2-1 triumph.
