A roundup for the week Oct. 18-24

BASEBALL—The St. Louis Cardinals defeated the Milwaukee Brewers 6-3 in the seventh and deciding game to win the World Series (page 26).

BOWLING—Top-seeded GUPPY TROUP defeated Jeff Bellinger 246-225 to win a $90,000 PBA event in Fairview Park, Ohio.

BOXING—LEROY HALEY retained his WBC super lightweight title with a 15-round decision over Giuseppe Gimenez in Cleveland.

GOLF—CALVIN PEETE fired a 16-under-par 268 to win the $200,000 Pensacola Open by seven strokes over Dan Halldorson.

HOCKEY—Boston, fresh from early-week wins over Calgary and Edmonton, brought a 5-1-2 record and a seven-game unbeaten streak into Vancouver to meet the struggling (2-6-1) Canucks. Third-period goals by Darcy Rota and Harold Snepsts snapped a string of five one-goal defeats for the home team, but for the Bruins the loss on the ice paled in comparison to the tragedy that befell their second-year forward, Normand Leveille, 19, who collapsed between the first and second periods. Leveille suffered a brain hemorrhage—triggered but not caused, doctors said, by a check by Vancouver's Marc Crawford in the opening period. At week's end he remained unconscious and was listed in poor condition in a Vancouver hospital. The Stastny brothers helped Quebec to a 2-1 week, but this time it wasn't Peter taking the lead role. Marian had three goals and Anton a goal and three assists in an 8-4 drubbing of Pittsburgh. Hartford's weekly win came 5-3 at the expense of Los Angeles, despite the absence of leading scorer Pierre Larouche (12 points in seven games), who was on suspension for a curfew violation. Mark Johnson had two goals for Hartford, including the tie-breaker with 7:49 left. Montreal stayed on top in the Adams Division by winning two of three. One of those wins came 2-1 over Philadelphia, which lost three of four and fell four points behind the first-place Islanders in the Patrick Division. The Isles' 5-4 victory over Vancouver was lowlighted by a replay of last year's stick-swinging duels between New York Goalie Billy Smith and Canuck Left Wing Tiger Williams. This time Smith apparently speared Williams, and Williams retaliated by swinging at Smith's head with his stick. That cost Williams an eight-game suspension. The NHL also handed out a six-game banishment to L.A.'s Jerry Korab for swinging his stick at Quebec Forward Dale Hunter, a notorious agitator, on Oct. 13. Following wins over Washington (6-3) and the Rangers (5-2)—thanks to three goals from Bryan Trottier and six points from Bob Bourne—the Isles were 26-0-2 in their last 28 games at home. Lowly Toronto made the biggest noise in the Norris Division, winning once and tying in two starts. Despite trailing division-leading Minnesota and Chicago by eight points, the Maple Leafs handed the North Stars their first loss, 5-2, and won their first game in the process. Newly acquired Center Greg Terrion scored twice in the victory. St. Louis lost 4-3 to Minnesota on a crazy play. Blues Goalie Mike Liut, in clearing a shot behind the net, hit Minnesota's Dino Ciccarelli with the puck. It bounced off Ciccarelli's shin pad—and up and over the net, whence North Star Tom McCarthy tapped in the winning goal. The Los Angeles Kings continued to pace the Smythe Division, as their rookie center, Bernie Nichols, scored two goals. That brought his season total to 12, tops in the league.

HORSE RACING—APRIL RUN ($4.60), Cash Asmussen up, beat Naskra's Breeze by 6½ lengths to win the $476,800 Turf Classic at Aqueduct. The 4-year-old filly ran the 1½ miles in 2:29[4/5].

Landaluce ($2.10), ridden by Laffit Pincay, scored a two-length victory over Sophisticated Gal to win the $259,350 Oak Leaf Stakes at Santa Anita. The 2-year-old filly covered the 1[1/16] miles in 1:41[4/5].

Princess Rooney ($2.60), Jacinto Vasquez aboard, ran a track-record 1:43 for 1[1/16] miles to win the $200,000 Gardenia Stakes at the Meadowlands. The 2-year-old filly beat For Once 'n My Life by 11 lengths.

Cast Party ($10.60), Jorge Velasquez up, defeated Pax In Bello by a length to win the $249,655 Laurel Futurity at Bowie. The 2-year-old colt covered the 1[1/16] miles in 1:45.

Castilla ($37), ridden by Ray Sibille, scored a two-length victory over Sangue in the $300,000 Yellow Ribbon Stakes at Santa Anita. The 3-year-old filly ran the 1¼ miles in 1:58[4/5].

MARATHON—ALBERTO SALAZAR outran Rodolfo Gomez by four seconds to win his third straight New York Marathon in 2:09:29. GRETE WAITZ was the first women's finisher, in 2:27:14, defeating Julie Brown by one minute and 19 seconds (page 24).

TENNIS—Top-seeded JIMMY ARIAS defeated Dominique Bedel 6-2, 2-6, 6-4 to win a $175,000 tournament in Tokyo, Japan.

Ivan Lendl overpowered Vitas Gerulaitis 6-2, 6-2, 7-5 in the finals of a $400,000 event in Melbourne, Australia.

Martina Navratilova defeated Tracy Austin 6-3, 6-3 to win a $125,000 women's Grand Prix event in Filderstadt, West Germany.

Brian Gottfried scored a 6-1, 6-4, 6-0 victory over Bill Scanlon to win a $100,000 Grand Prix tournament in Vienna.

WEIGHTLIFTING—TOM HARDMAN, 29, set a world record for the bench press when he lifted 614.4 pounds at the Georgia Elite Powerlifting Championships in Atlanta.

MILEPOSTS—FIRED: For the sixth time in his stormy 12-year managerial career, BILLY MARTIN, 54, by the Oakland A's after three seasons in which he had a 216-118 record and won the 1981 American League Western Division title. The A's fell to 68-94 and fifth place this year.

RESIGNED: As manager of the California Angels, GENE MAUCH, 56, following a 93-69 season in which the Angels reached the American League Championship Series. In his two seasons with California, Mauch had a 144-128 record; his 23-year managerial mark is 1,646 wins, 1,808 losses.

For the second time as the Cleveland Cavaliers coach, BILL MUSSELMAN, 42. His replacement is former Utah Jazz Coach TOM NISSALKE, 48. Musselman, who also resigned during the 1980-81 season, quit this time six games into the preseason, in which he had a 1-5 record; he replaced Chuck Daly last year and won just six of 42 games as the Cavs closed the season with a record-tying 19 straight defeats.

RETIRED: Senior American League Umpire BILL HALLER, 47, after 20 years of service.

TRADED: To the New York Knicks, Forward BERNARD KING, 25, of the Golden State Warriors for Guard MICHAEL RAY RICHARDSON, 27, and future considerations.

By the Indiana Pacers, Forward LOUIS ORR, 24, to the Knicks for a second-round 1983 draft pick and future considerations.

DIED: Former Pittsburgh Steeler and University of Pittsburgh Football Coach JOHN MICHELOSEN, 66, who succeeded Jock Sutherland as Steeler coach and from 1948 to '51 had a 20-26-1 record. He then led Pitt to a 56-49-7 mark from 1955 to '65, including a 9-1 season in '64, when the Panthers were ranked No. 3 nationally; of a heart attack; in San Diego. Michelosen played single-wing quarterback under Sutherland at Pitt (1935-37) and became the last pro coach to run the single wing.
