A roundup of the sports information of the week

BASKETBALL—NBA: BOSTON (37-18) scrambled to a two-game lead in the Eastern Division with three wins and two losses, while CINCINNATI (35-20), briefly in first place only a week earlier, dipped all the way to third before ending the week in second after winning one out of four. PHILADELPHIA (34-20) lost three to shatter its eight-game winning streak, and NEW YORK (19-34), of all teams, won all three games it played. LOS ANGELES (33-26) took two and lost one to move six games ahead in the West, while SAN FRANCISCO (26-31) climbed past the Bullets into second place with two out of three before settling back into third at week's end. BALTIMORE (27-32) and ST. LOUIS (25-33) each split four games, and last-place DETROIT (17-39) won one of three.

BIATHLON—JON ISTAD, a 28-year-old Norwegian carpenter, skied through heavy fog over the 20-kilometer course at Garmisch-Partenkirchen, Germany to win the world championship in 1:38:21.8.

BOATING—JOE DUPLIN of Boston, the 1963 world Star champion, defeated James (Dink) Schoonmaker of Miami by two points (138-136), to take the Star Class Bacardi Cup on Biscayne Bay in Miami with 3-1-6-6-1 finishes. Duplin had won the first three races in last year's cup but was declared ineligible because he was sailing a yacht from France, not one from his home fleet.

Skidoo, a 36-foot sloop skippered by Walt Swindeman of Toledo, won the 105-mile St. Petersburg-to-Venice race on a corrected time of 12:45.21, but the results were nullified by a three-man jury after four skippers complained they lost time looking for a buoy marking the course. The judges upheld the protest because the Coast Guard had changed the sequence of flashes on the designated buoy.

Earlier Elma had won the International Trotting Championship of Europe for 1965, but the French refused to award her the annual gold cup because she is not European owned or bred.

HORSE RACING—GRAUSTARK ($2.60), John Galbreath's Derby candidate, won his fifth straight race when he came from behind in the stretch to beat Ogden Phipps's Impressive by four lengths in the $29,950 Bahamas at Hialeah.
