A roundup of the week Jan. 25-31

BASKETBALL—NBA: Boston and New York traded spine-tingling victories (page 12), and by week's end the Celtics, with three of five wins overall, led the Knicks, winners of three of four, by 4½ games in the East Division. Central leader Baltimore edged closer to a .500 record (24-26) with three straight wins, defeating Cincinnati twice—132-101 on 43 points in the last period and 132-124—and Buffalo 115-114 when Wes Unseld scored a basket with one second left in overtime. With Pistol Pete Maravich feeling better and scoring more, second-place Atlanta, five games out, won three of four, including a 118-113 victory over Milwaukee as Maravich popped in 35 points (14 in the last five minutes) and made 14 assists, and a 123-110 win over Buffalo as Pistol Pete tossed in 28. Milwaukee held its 4½-game lead over Chicago in the Midwest when both teams took three of four, while Golden State chipped half a game off of Los Angeles' Pacific Division lead (11½) by winning four of five as the Lakers snapped out of their mild slump with two wins in a row. The Warriors' 11-game victory streak was stopped by the Bulls 110-105, and Cleveland's 11-game losing streak came to an end when the Cavs, bolstered by the return of rookie Austin Carr, who had been out with a bad foot since Dec. 8, unexpectedly dumped Boston 112-108.

ABA: Kentucky, the East leader, and Utah, tops in the West, both increased their leads in the divisional races before taking a break for the All-Star Game. The Colonels split four games, walloping the Stars by 36 points and edging Indiana 98-94, arid losing to New York by 13 and to Memphis 107-99 to snap a 10-game road victory streak. Runner-up Virginia, eight games behind, dropped three, including a 130-123 loss to Denver despite league-scoring leader Charlie Scott's 50 points. Third-place New York picked up 2½ games on the Squires and climbed to within 5½ of second by winning three of four. The Nets beat the Floridians 116-105, the Colonels 118-105 as rookie John Roche scored 31 points and the Squires 114-112 when Rick Barry, who scored 44, popped in an 18-foot jumper with four seconds to go. In New York's only loss, 123-116 in overtime to Pittsburgh, the Condors outscored the Nets 11 points to one in the last 3½ minutes of the fourth period, then hit 11 straight points in the first 2½ minutes of the overtime period. Utah's lead over Indiana in the West climbed to four games as the Stars won two of three and the Pacers beat only the Floridians in three games.

The favored EAST, paced by Carolina rookie Jim McDaniels' record 18 points in the final period, put on a dazzling display of fast breaks and accurate passing late in the contest to overwhelm the West 142-115 in the ABA All-Star Game in Louisville.

HOCKEY—First-place Boston pulled five points ahead of New York in the East by tying Buffalo 3-3 on Dallas Smith's 50' slap shot midway in the third period and beating Philadelphia twice 4-2, as the Rangers split two games. In the first Bruin win over the Flyers, Phil Esposito knocked in three goals to bring his season total to 42, making him only the second player in NHL history to score 40 or more goals in four consecutive seasons (Bobby Hull was the first). In a rare occurrence, the Canadiens' Frank Mahovlich and the North Stars' Lou Nanne each scored three goals in the same game, and Nick Libett slapped in three in Detroit's 3-1 win over Buffalo on the same night Esposito gained his hat trick. Minnesota won three—5-3 over Los Angeles, 6-5 over Montreal and 4-2 over New York—but still remained 10 points behind West leader Chicago, which also took three in a row. The Black Hawks' Tony Esposito gained his fifth and sixth shutouts of the season in 4-0 victories over Toronto and Vancouver and extended his shutout string to three. Gary Smith was in the goal for the Hawks' 4-2 win over Pittsburgh.

The favored EAST edged the West 3-2 in the NHL All-Star Game in Bloomington, Minn. as Jean Ratelle, John McKenzie and Phil Esposito scored consecutive goals to overcome a 2-0 second-period West lead. Gilles Villemure look over for Ken Dryden in the East nets midway through the second period and shut out the West the rest of the way.
