A league playoff record crowd of 19,974 in Cleveland's Coliseum watched Washington beat the Cavaliers 100-95 in the opening game of their best-of-seven series. In the next game Bingo Smith, the only original Cavalier still with the club, canned a 22-foot jumper to give Cleveland an 80-79 victory, and he and Austin Carr each scored 17 points in the third game, which the Cavs won 88-76 before a record-breaking Coliseum throng of 21,061, giving Cleveland a 2-1 edge.

ABA: Kentucky won its preliminary series with Indiana and went on to meet regular-season champion Denver in a best-of-seven.
