PRO BASKETBALL—NBA: Chicago's bulldozing Chet Walker celebrated becoming only the eighth man in league history to play in 1,000 games by scoring 17 points in a 116-96 victory over Detroit. The Bulls and the Pistons both were undefeated during the rest of the week as Detroit maintained a one-game lead over Chicago in the Midwest. Milwaukee suffered back-to-back losses to Houston and Atlanta, and Central Division leader Washington beat second-place Cleveland 94-92 for its fifth straight win. The Bucks beat Portland earlier in the week, but Trail Blazer fans greeted Bill Walton with a standing ovation before a game with Philadelphia. He responded in the win with 13 points, 13 rebounds, seven assists and five blocked shots. Kansas City-Omaha's Nate Archibald had 40 points as the Kings beat New York 112-103. The Knicks also lost to Buffalo, with playmaker Ernie DiGregorio back in action. Boston won four games and held the Atlantic Division lead by 1½ games. After losing to Boston, Houston's seventh straight loss, the Rockets won their next two games.

Rick Barry of the Warriors scored 55 points, high in the league this season, in a victory over injury-riddled Philadelphia. Seattle had no wins for the week and ended up with Phoenix and Portland in contention for the runner-up spot in the Pacific.

ABA: Denver, the best team in the Western Division, lost only 10 games all season, and three of the losses came during the week. Kentucky, Indiana and Utah all set the Nuggets back, but Denver still led the division by a comfortable 11½ games. George McGinnis. the league-leading scorer, had 43 points and 20 rebounds in the Pacers' 120-110 victory over the Nuggets, but San Antonio had held Big George in check a night earlier and won 110-91. The Spurs also beat St. Louis, while the Spirits outlasted San Diego in overtime. Memphis, triggered by Tom Owens' 32 points and 18 rebounds, defeated St. Louis 107-103. New York's Julius Erving has scored 40 or more points in three games this season—all against Kentucky. The Nets, leaders in the East, kept the Colonels a game to the rear with a 112-110 victory in which Dr. J tallied 42 points but required two successful free throws by Brian Taylor with three seconds to go to clinch the win. San Diego's lone win came against last-place Virginia, which had a 0-3 week.

The California Seals beat Toronto for their first win under Bill McCreary, who replaced the fired Marshall Johnston.

WHA: The Michigan Stags began the second half of the season as the Baltimore Blades, a franchise shift necessitated by financial problems.
