A roundup of the week Jan. 28-Feb. 3

PRO BASKETBALL—NBA: At the All-Star break, the league's tightest race was in the Pacific Division, where Los Angeles trailed Seattle by half a game. The Sonics snapped a three-game losing streak with a 105-101 win over Milwaukee, but the Lakers beat the Bucks 112-102, too. They lost 154-153 at Cleveland and defeated Chicago 107-97 to run their recent record to nine wins in 11 games. The loss to the Cavaliers came in four overtimes, with Cleveland's Mike Mitchell sinking two free throws with two seconds remaining. That same night, in San Diego, the Clippers broke a losing streak at six by beating Phoenix 133-121, but the big news in that game was the return of Bill Walton (page 20). In the Midwest, Kansas City moved five games ahead of Milwaukee, which had just one win, a 103-96 defeat of Portland. The Kings beat Denver 121-111 behind Otis Birdsong's 49 points and Seattle 99-97 on Birdsong's 20-foot jump shot with two seconds to go. K.C. then lost 94-93 to the Trail Blazers. Atlanta got some breathing room over San Antonio in the Central Division by beating the Spurs 118-111 to snap a four-game San Antonio winning streak. The Hawks went on to defeat Washington 98-82 and Golden State 111-107 in overtime to pull away by 2½ games. In the Atlantic Division, Boston stayed ahead of Philadelphia with four straight triumphs—131-108 over San Diego, 103-99 over Chicago, 110-103 over Cleveland and 119-103 over Washington. The 76ers went 2-2, losing 125-118 at Phoenix, despite 34 points from Darryl Dawkins (page 32), and 107-101 at Utah. Philadelphia then managed wins over Detroit (121-108) and Houston (110-105). In a 107-103 Knick triumph over Golden State, New York Coach Red Holtzman got his 600th career victory. The Knicks then beat Indiana 112-102 for their fifth victory in a row.

JoAnne Carner beat Sandra Post by two strokes to win the $100,000 Whirlpool Championship of Deer Creek in Deerfield Beach, Fla., with a 10-underpar 282.

HOCKEY—NHL: As the All-Star Game approached, Minnesota, once unbeaten in 22 straight games but now winless in seven, had high hopes for its meeting with Vancouver. The Canucks, after all, had been winless in 11 games. In a brawl-filled game in which the officials assessed 180 minutes in penalties, Vancouver won 5-4. Los Angeles sustained its fourth defeat in a row, 5-4 to Montreal, while Quebec ended its week with a 7-2 loss to Boston, leaving the Nordiques winless in four games. The Bruins, on the other hand, were 3-2-0 since three of their players were suspended on Jan. 25 for fighting and were in third place with 68 points, two behind second-place Buffalo and 14 behind No. 1 Philadelphia. Edmonton beat Winnipeg 9-2 as Wayne Gretzky had a hat trick and tied Colorado 2-2. Hartford defeated Atlanta 6-1 on a Blaine Stoughton hat trick and Boston 8-2 as Mike Rogers scored three goals and Mark Howe had five assists. Pittsburgh's switch to Steeler-Pirate championship black and gold—the Penguins had formerly worn blue-and-white uniforms—was ruined by 4-3 losses to St. Louis and Detroit. The Red Wings' Mike Foligno got his second hat trick of the week in that victory. The Penguins sustained their third consecutive defeat, 4-0 at the hands of league-leading Philadelphia, which was unbeaten in 10 games. In helping the Rangers overcome Washington 6-3, Phil Esposito scored his 699th and 700th goals, placing him second to Gordie Howe on the alltime list.
