A roundup of the sports information of the week

BASKETBALL—ABA: In a week of sparse action all around the league first-place PITTSBURGH (44-21) increased its Eastern Division lead to three games with four straight wins. Two of the victories were over the second-place Muskies—120-115 and 110-102—as Connie Hawkins totaled 105 points and took over the ABA scoring lead from the Americans' Levern Tart, the leader the past 16 weeks. MINNESOTA (42-25) won its other two games and held a 10-game lead over third-place NEW JERSEY (31-34), which lost to Denver 110-108. INDIANA (32-35) restored Jim Rayl to the starting lineup for the first time in a month and he scored 33 points in a 123-110 win over Denver, while KENTUCKY (27-36), with Darrel Carrier tossing in 43 points, beat Indiana 134-129. In the Western Division, NEW ORLEANS (40-25) saw its lead slip to three games when the Bucs split two and runner-up DALLAS (35-26) won two of three, including a wild 148-130 victory over Oakland that set an ABA team scoring record. DENVER (37-29) dropped three of five and HOUSTON (24-41) won three of four, while OAKLAND (21-39) lost all four games it played but stayed two games ahead of last-place ANAHEIM (21-43) when the Amigos dropped two.

NBA: PHILADELPHIA (50-17) won two games and lost one—to the lowly Rockets, of all teams. The loss was only the third for the 76ers in their last 19 games. In a 138-117 victory over Detroit, Wilt Chamberlain had 32 rebounds, 12 assists and 31 points—which gave him a career total of 25,022 points, making him the first ever to pass 25,000. Ironically, Wilt, whose lifetime foul-shooting percentage (.522) is one of the worst in NBA history, passed the magic mark with a successful foul shot. BOSTON (45-22) dropped three of five and fell five games behind the 76ers. NEW YORK (35-33) won its only two games for the Knicks' eighth victory in their last 10. What's more, the Knicks went over the .500 mark for the first time in nine years so late in the season when they beat the Warriors in overtime 115-112 before 19,500 at the new Garden. It was the largest crowd ever to see an NBA game. Fourth-place CINCINNATI (31-38) won its fourth straight game, beating the Celtics 107-100, but then lost Oscar Robertson again with an injury, and the Royals dropped their next four games. BALTIMORE (31-38) moved out of the cellar and climbed within half a game of the Royals by winning four of five and eight of its last 11. Once again rookie Earl Monroe was NBA high scorer for the week with 49 points against DETROIT (30-38), which lost four of five. In the West, ST. LOUIS's (48-22) lead widened to seven games despite splitting four games. LOS ANGELES (39-27) was the new tenant in second place as the Lakers won two to make it six victories in their last eight games. Three straight losses followed by two wins dropped SAN FRANCISCO (41-29) to third place, while fourth-place CHICAGO (24-44) won three in a row before losing to the Knicks. SEATTLE (20-48) won one, lost three, and SAN DIEGO (15-53) finally broke its 17-game losing streak with the 111-106 upset of the 76ers.

GOLF—GEORGE KNUDSON of Toronto became the first golfer to win back-to-back tournaments on the PGA tour in two years when he took the $100,000 Tucson Open with a 72-hole score of 273, finishing one stroke ahead of runners-up Frank Beard and Frank Boynton.

HARNESS RACING—Stanley Dancer drove CARDIGAN BAY ($3.20), the 12-year-old New Zealand gelding, to a length and a half win over another Kiwi pacer, Great Credit, in the $25,000 Valley Forge Pace at Roosevelt Raceway. The victory increased Cardigan Bay's lifetime winnings to $917,571, only $5,045 below alltime harness leader Bret Hanover.

HOCKEY—NHL: East leader MONTREAL (34-16-9) won two games before its eight-game winning streak was snapped by the Rangers (page 18). CHICAGO (28-18-14), seven points behind in second place, won two and tied one, beating the Red Wings 7-1 on hat tricks by Stan Mikita and Kenny Wharram (each also had two assists) and the Seals 1-0 in the last three minutes on Bobby Hull's 41st goal. NEW YORK (28-19-11) beat the Flyers 3-1, lost to the Canadiens 7-2 at home and then whacked the Canadiens 6-1 in Montreal as Rod Gilbert scored four goals. The loss to the Canadiens broke the Rangers' eight-game unbeaten streak. BOSTON (28-22-10) split four, with its two wins coming in dramatic fashion. Glen Sather scored with 1:54 left to beat the Kings 6-5 and John Bucyk scored with one second remaining to beat the Wings 3-2. TORONTO (24-24-9) broke a seven-game losing streak when rookie Jim McKenny scored his first NHL goal of the season in the third period to give the Maple Leafs a 1-0 win over the Bruins. DETROIT (21-28-10) also recovered from a skid—eight games without a victory—by defeating the North Stars 3-1. The Red Wings had lost their first two games in the week, making their record 15 defeats in their last 23 games. Western leader PHILADELPHIA (26-23-9) lost to the Rangers 3-1, tied the Penguins 1-1 on a second-period goal by Andre Lacroix, who was playing his first NHL game, and walloped the North Stars 7-3 as Leon Roche-fort had a hat trick and Lacroix scored another goal and made three assists. MINNESOTA (23-26-10) remained five points behind in second place with one victory, two defeats, while LOS ANGELES (24-28-6) lost one and tied one. ST.
