PRO BASKETBALL—In the first round of the NBA playoffs the Celtics produced perhaps the worst massacre in Boston since 1770. In fact, it has been almost that long since the last time the Knicks won at Boston Garden. Boston's 157-128 victory in Game 2 of their best-of-five series was its 26th straight over New York on the parquet floor; the Celtics also established an NBA record for points in a playoff game, breaking the Bucks' mark of 156 in 1970. Eight Celtics, led by Kevin McHale with 31 points, scored in double figures as Boston jumped to a 2-0 series lead. Two days earlier Larry Bird had sparked the Celtics to a 116-105 win with a triple double (24 points, 18 rebounds, 10 assists). The Pistons had similar success against the Pacers. James Edwards led Detroit with 21 points in a 104-92 triumph in Game 1, and Bill Laimbeer got 22 in the Pistons' 100-87 victory in the second game. The Bulls charged through the opening two games against the Bucks, winning 111-97 and 109-102, to give Chicago 13 wins in its last 14 games against Milwaukee. Michael Jordan had 38 points in the first game and 36 in the second. Charles Barkley carried the 76ers to a 2-0 lead over the Cavaliers. In Game 1, Barkley scored 38 points and had 21 rebounds, including 11 on the offensive end, which was one more than Cleveland's team total. He had 32 points and eight rebounds in the second game. David Robinson showed why he was named the league's Rookie of the Year, with a pair of dominating performances—he scored 57 points and had 25 rebounds—as the Spurs took a 2-0 series lead against the Nuggets by scores of 119-103 and 129-120. The Trail Blazers also won the first two games of their series against the Mavericks. Terry Porter had 28 points, including nine on free throws in the final minute, to lead Portland to a 109-102 triumph in Game 1. Buck Williams took over in the second game with 16 points and 13 rebounds as the Blazers won 114-107. The Lakers blocked 11 Rocket shots in a 101-89 victory in their series opener. Houston retaliated in Game 2, as Akeem Olajuwon tied a playoff record, with 10 blocked shots, and the Rockets stormed to a 17-point halftime lead. But James Worthy led a furious Laker comeback in the second half, including scoring five of his 32 points in the final 1:19 as Los Angeles survived, 104-100. The Suns were the only team to win a playoff game on the road at week's end, taking Game 2 at Utah, 105-87, after the Jazz had won the opener of the series, 113-96 (page 26).

HOCKEY—In the Norris Division finals, the Blackhawks couldn't seem to find a cure for the Blues as long as St. Louis's Brett Hull had the puck on his stick. Hull, who at week's end led all playoff scorers with 13 goals, sent the series to a seventh game by scoring two goals in the Blues' 4-2 win in Game 6—after Chicago had surged ahead three victories to two, with a pair of 3-2 triumphs in Games 4 and 5. Blackhawks Wayne Presley and Michel Goulet scored 36 seconds apart in the second period of the fourth game, and goalie Ed Belfour stopped 18 of 20 shots to stymie St. Louis in Game 5. The survivor in the Norris will begin play this week against the Oilers, who completed a sweep of the Kings in the Smythe Division finals, for the Campbell Conference title. Lacking Wayne Gretzky, who was forced to sit out the contest with a back injury, L.A. dropped Game 4 as Joe Murphy scored off a rebound at 4:42 of overtime to give Edmonton a 6-5 victory. In the Wales Conference, the Capitals, who beat the Rangers in five games to win their first Patrick Division crown (page 34), and the Bruins, who knocked off the Canadiens, also in five games, to prevail in the Adams Division (page 18), will meet for the championship.
