A roundup of the week Sept. 13-19

BASEBALL—SOUTH KOREA upset Japan 5-2 to win the 27th World Amateur Baseball Championship in Seoul. The U.S. placed third.

BOXING—JUAN LaPORTE won the WBC featherweight title, left vacant by the death of Salvador Sanchez, when Mario Miranda could not answer the bell for the 11th round of their bout in New York City.

Michael Spinks stopped Johnny Davis in the ninth round to retain his WBA light heavyweight title in Atlantic City.

Rafael (Bazooka) Limon successfully defended his WBC super featherweight championship by knocking out Chung Il Choi in the seventh round in Los Angeles.

Hilario Zapata scored a split decision over Chang Chong-ku to retain his WBC light flyweight title in Chonju, South Korea.

PRO FOOTBALL—The season's second week—and perhaps its last for a while because of the strike—got off to a flying start in Buffalo Thursday night. Joe Ferguson passed for 330 yards and three touchdowns to rally the Bills from a 19-0 deficit to a 23-22 victory over Minnesota. Afterward Ferguson said, "We don't want a strike. We want to keep playing. There's no telling what might happen to a team with three weeks' layoff." Maybe, Ferguson no doubt fears, the same thing that has happened to San Francisco in the eight months since the Super Bowl. The 49ers lost their second in a row when Rich Karlis hit a last-second, 18-yard field goal to give Denver a 24-21 come-from-behind win at Mile High Stadium. Kansas City's Nick Lowery, who kicked four field goals, was chiefly responsible for a 19-12 defeat of San Diego, but K.C. Cornerback Gary Green provided most of the excitement when he blocked a Maury Buford punt at the San Diego 25. A few Chargers and too many Chiefs got a hand on the elusive ellipsoid before it came to rest in the arms of Kansas City Linebacker Dave Klug, prone in the end zone. In Houston, Earl Campbell rushed for 142 yards, his first 100-yard effort in 10 games, and scored on a 12-yard ramble with 53 seconds left as the Oilers defeated Seattle 23-21. In other games, Los Angeles' two teams continued to head in opposite directions as the Raiders overwhelmed Atlanta 38-14 and the Rams fell to unbeaten Detroit 19-14; New Orleans under new old Quarterback Ken Stabler beat Chicago 10-0; the New York Jets capitalized on three interceptions to rip New England 31-7; Washington outsplashed Tampa Bay 21-13 in heavy rain; Philadelphia scraped by Cleveland 24-21 on the strength of three fourth-quarter touchdowns; Miami held off determined Baltimore 24-20; and Dallas dispatched St. Louis 24-7, evening its record after losing its opener for the first time in 18 years, 36-28, to Pittsburgh on Monday. Steeler Quarterback Terry Bradshaw passed for 246 yards and three touchdowns that night, and Franco Harris ran for 103 yards. "Not bad for a couple of dinosaurs," said Bradshaw. Six days later, the Steelers again walked tall, upsetting Cincinnati 26-20 in overtime (page 18).

MOTOR SPORTS—Rookie HECTOR REBAQUE, in a March-Cosworth, won his first Indy-car race, the Road America 200 in Elkhart Lake, Wis., when Al Unser ran out of fuel on the last lap. Rebaque averaged 109.156 mph around the four-mile, 14-turn circuit. RICK MEARS finished fifth, good enough to clinch his second straight CART championship.

Darrell Waltrip, in a Pontiac, averaged 107.23 mph around the 1-mile Dover (Del.) Downs International Speedway oval to win a 500-mile NASCAR Grand National stock car race, his ninth victory of the year. He beat Kyle Petty, in another Pontiac, by half a car-length.

SAILING—MARK GOLISON clinched the USYRU men's championship with a low score of 23 in an eight-race series in matching J-24 sloops on Long Island Sound. He defeated Charles Scott by 5.5 points.

SOCCER—Giorgio Chinaglia's first-half goal was enough to carry the Cosmos to their second Soccer Bowl victory in three years, 1-0 over the Seattle Sounders, in San Diego (page 56).
