A roundup of the week Jan. 21-27

PRO BASKETBALL—NBA: After starting the week with a 118-93 victory at Denver, Philadelphia had its winning streak stopped at nine games, losing 124-103 to Los Angeles. The 76ers stayed half a game ahead of Boston in the Atlantic Division as the Celtics went 2-2, losing to Seattle 108-106 in double overtime and narrowly defeating Houston 112-106 after blowing a 22-point lead. Boston then triumphed at Detroit 131-104 and sustained a rare defeat at home, 118-107 to Washington. In the Central Division, Atlanta again lost ground to San Antonio, losing to Kansas City 101-89 and Seattle 98-96 before beating Chicago 109-104. The Spurs now trail by just a game. The loss to San Antonio broke an eight-game win streak by the Pacific Division-leading Sonics. Seattle's successes included the double-overtime victory over the Celtics, in which Gus Williams scored 29 points, and a 98-96 defeat of Atlanta. Williams capped a 35-point performance in that game by hitting a three-pointer with six seconds remaining. Los Angeles ran its winning streak to six with a 132-114 triumph over New York, but then fell victim to a Portland streak. The Trail Blazers beat the Lakers 111-103 to register their third victory in three games with L.A. this season. Kansas City, first in the Midwest, had the best week among division leaders, 3-1, but even the Kings' luck was mixed. In a 110-88 defeat of Utah, in which seven K.C. players scored in double figures, Forward Scott Wedman, who was to have participated in the All-Star Game on Feb. 3, took an elbow from the Jazz' Jerome Whitehead. He will be lost for at least two weeks with a fractured left cheekbone. The Kings then lost 113-107 to Chicago after Reggie Theus hit a three-pointer with 10 seconds left to send the game into overtime. The Bucks remained four games behind Kansas City by splitting four games. Milwaukee's Brian Winters pulled out an 89-88 win over Portland by making a jumper with four seconds to go. Two other Bucks games were also close, Milwaukee falling 127-122 to Utah in overtime and beating Golden State 104-102. After losing twice early in the week, the troubled Bullets broke a run of six losses, their longest downturn in 12 seasons, by beating Boston 118-107 (page 26).

WBL: Despite a 104-101 loss to San Francisco and a 101-98 overtime defeat at the hands of New Jersey, Eastern Division-leading New York still paced the league with a 17-4 record. Iowa (14-5) remained tied with Minnesota atop the Midwest Division, and Western leader San Francisco (14-9) was victorious in two of three.

BOWLING—HUGH MILLER, 23, of Mercer Island, Wash. defeated top-seeded Tom Kress of Rochester, N.Y. 238-226 to win a $100,000 PBA tournament in Grand Prairie, Texas.

GOLF—TOM WATSON shot a 13-under-par 275 to tie D. A. Weibring and beat him by one stroke on the first hole of sudden death to win the $250,000 Andy Williams-San Diego Open.

HOCKEY—NHL: After wins over Montreal, 2-1, and Detroit, 5-3, the New York Islanders skated a penalty-free game—only their second in history—in beating Hartford 3-2. And although the Isles stood in seventh place in the league with 52 points, theirs was the second-longest ongoing winning streak at seven. The Flyers, who have 76 points, scored their latest victories against St. Louis, 3-1, Chicago, 4-1, and lowly Winnipeg, 5-4, which is last in the NHL with 31 points. In second place with 66 points, Buffalo had a so-so week, tying Edmonton 4-4 and Atlanta 3-3 arid losing to Boston 4-3 before winning easily at Montreal 7-2. The Sabres' triumph came without Coach Scott Bowman behind the bench. When he quit as the Canadiens' coach after last season, he swore he'd never again coach a regular-season game in The Forum. So far he has lived up to his word. After home victories over Minnesota 3-0—Gerry Cheevers got his 25th NHL shutout in that one—and Buffalo 4-3, Boston lost three players to league suspension (page 16). Nevertheless the Bruins beat Pittsburgh 6-4, sending the Penguins to their fifth straight defeat while stretching their own winning streak to eight. Steve Shutt's four goals in a 7-2 triumph at Hartford was the lone bright spot in a 1-2 week for Montreal. The win kept the Canadiens in fourth place with 56 points, just two more than the Rangers, who lost 2-1 to Chicago and beat Los Angeles 5-4 on a hat trick by Ron Duguay and Vancouver 6-4 as Duguay had two goals and an assist. In an 8-3 Edmonton win over Toronto—the Oilers' Blair MacDonald got his second hat trick in two weeks.
