On this day in Boston Celtics history, the franchise became the first team in NBA history to win 61 games in a single season in 1965, besting their own record from the 1961-62 campaign.
The big win came in a 106 – 98 victory over the (then) San Francisco (now, Golden State) Warriors at the old Boston Garden that saw iconic Celtics center Bill Russell lead Boston with 20 points, 41 rebounds and 4 assists to secure the win. Veteran guard Sam Jones added 24 points and 5 boards, and forward chipped in John Havlicek 22 points and 6 rebounds.
The Celtics would close the season with one more win to push the record to 62 wins with a victory over the (then) Cincinnati Royals on March 21.
