PRO BASKETBALL—While Boston assured itself of having the best record for the season with defeats of Cleveland (98-86 and 113-94) and Chicago (117-110), at the other end of the Atlantic Division standings Washington clinched the last Eastern Conference playoff berth with a 106-94 victory over Indiana in which Jeff Ruland had 18 points, 13 rebounds and a career-high 12 assists. The Bullets were battling it out for the No. 7 spot with the Atlanta Hawks, whose two wins on the week included a 122-103 beating of the Pacers.

Washington had Philadelphia on the ropes, leading 2-0 in games and 1-0 in the first period Saturday night, so several Flyers responded like the Broad Street Bullies of old. Defenseman Darryl Stanley hit Washington forward Mike Gartner, and the Sutter twins, Rich and Ron, dropped their gloves and went after the Caps' Bobby Carpenter and Darren Veitch, respectively. All three aggressors, along with Carpenter and Veitch, were ejected, and Washington won 5-1 to clinch the series. The Islanders' 4-1 victory in Game 1 of their Expressway Series with the Rangers got the Isles off to a hot start in their pursuit of a fifth consecutive Stanley Cup. But hotter still was Ranger goaltender Glen Hanlon, who had 45 saves in the Rangers' 3-0 shutout in Game 2 and 26 more in a 7-2 victory on Saturday.
