BASKETBALL—NBA: Philadelphia (52-10) lost another half a game of its Eastern Division lead as the 76ers won three of five, while BOSTON (45-14) took three of four. The Celtics—now 5� games behind—beat Western Division leader San Francisco 137-136 in double overtime when Tom Sanders tipped in a rebound with 18 seconds left, and two days later edged the 76ers 113-112. NEW YORK (31-32) opened the week with a loss, but came back to win three games, by a total of seven points, and moved three games ahead of the Royals in the battle for third place. CINCINNATI (26-33), which won two and lost three, ended a five-game losing streak by beating the Pistons twice in a row, while last-place BALTIMORE (16-48) closed out a surprising 3-2 week by defeating both the Celtics and 76ers. In the West, SAN FRANCISCO (36-26) lost four games in a row. Worse yet, the Warriors lost Center Nate Thurmond, possibly for the rest of the season, when he broke two bones in his left hand during a scramble for a loose ball in the game against the Celtics. Second-place ST. LOUIS (29-32) won three of four and climbed to within 6� games of the Warriors, while LOS ANGELES (26-34), in third, also won three of four.

DETROIT (21-25-3), with two wins, one loss, climbed past TORONTO (18-21-9) into fourth place as Norm Ullman scored three quick goals in a 5-2 win over the Maple Leafs. The loss was the 10th in a row for the Leafs, the longest losing streak in the NHL since 1962. But the string finally ended when the Maple Leafs tied the Hawks and beat the Bruins 2-1 to tie the Wings for fourth. Last-place BOSTON (13-31-7) halted a run of five straight losses with a 2-1 victory over the Rangers, then lost its next two games.
