BASKETBALL—NBA: Boston began pursuit of its 13th league championship by taking a 2-1 lead over Buffalo in their best-of-seven series. John Havlicek suffered an injured left foot as the Celtics won the opening game 107-98. His replacements, Don Nelson and Steve Kuberski, powered the Celtics to a 101-96 victory before Buffalo rebounded at home with a 98-93 triumph as Randy Smith and Bob McAdoo combined for 53 points. Washington ended a four-game home losing streak by ripping Cleveland 109-98 as reserves Clem Haskins and Nick Weatherspoon contributed a total of 41 points, but the Cavaliers, playing before a record playoff crowd of 21,312 back home, nipped the Bullets 92-91 on Jim Cleamons' last-second rebound tip-in to take a 3-2 series lead. Defending champion Golden State, idle for 10 days, split with Detroit at home, winning the opener 127-103, then losing 123-111 as the Pistons' Curtis Rowe had 33 points, 10 rebounds, three assists and three steals. The Warriors then ripped the Pistons 113-96 in Detroit. Seattle lost to Phoenix 130-114 to fall behind three games to one, but avoided elimination with a 114-108 win on Sunday.
ABA: The semifinals were marked by last-second game savers. Ex-Net, now-Spur Larry Kenon hit two free throws with three seconds left to give San Antonio a 106-105 win over New York that tied their series at 3-3. George Gervin scored 37 points for the Spurs, while Julius Erving had 41 for the Nets, including 31 in the second half. The Nets won the series back home as Rich Jones, whom Coach Kevin Loughery asked to sit out the sixth game because of the abuse he was getting from San Antonio fans and management, repaid Net fans for his warm "welcome home" by scoring 25 points in a 121-114 victory. Trailing two games to one, Denver downed Kentucky 108-106 when Chuck Williams hit a 24-foot jump shot at the buzzer. The Nuggets moved ahead three games to two when reserves Byron Beck and Gus Gerard fueled a second-half blast that fried the Colonels 127-117. Kentucky evened the series on a 119-115 double-overtime shootout, fever-ridden Bird Averitt scoring 34 points.

The Islanders then eliminated the Sabres with a 3-2 win and now meet the Montreal Canadiens in the semifinals. Philadelphia and Toronto matched home-ice victories—Don Saleski's hat trick boosting the Flyers and Darryl Sittler's record-tying five goals powering the Maple Leafs—before the Flyers won the penalty-marred series with a 7-3 triumph in the seventh game. Referee Wally Harris called a record 185 penalty minutes in the sixth game at Toronto, and one more Flyer was charged with assault: Bob (Hound) Kelly, whose airborne glove allegedly struck usherette Jan Brown, the wife of NHL Linesman John Brown, who did not work the game. Boston and Los Angeles also swapped home-ice victories before the Bruins beat the Kings 3-0 Sunday night to win the playoff. They now play the Flyers.

In the other U.S. semifinal, New England took a 3-2 series lead over Indianapolis with 3-0 and 2-1 victories at home in Hartford, but Goaltender Jim Park blanked the Whalers 4-0 back in Indianapolis as the Racers fought off elimination.
