PRO BASKETBALL—While Bill Walton's inspired play led Portland's 4-0 blitz of Los Angeles (page 28), Houston took two of three games from Philadelphia to cut the 76er lead to 3-2 in the Eastern semifinal. Facing elimination Sunday afternoon at Philadelphia, the Rockets overcame a 17-point deficit to win 118-115. Mike Newlin scored 19 points coming off the bench and Moses Malone had 19 rebounds and 17 points for Houston. Earlier, Malone scored 30 points and had 25 rebounds in Houston's 118-94 triumph in Game Three Wednesday night, as the Rockets cut the 76ers' series lead to 2-1. Two nights later Doug Collins scored 36 points, Julius Erving added 29 and Philadelphia romped 107-95. The key to that win, claimed 76er Coach Gene Shue, was Center Caldwell Jones, who held Malone to five points and 13 rebounds. Another key—for Houston, that is—may have been the fractured rib, collapsed lung and bruised chest wall suffered by 76er Guard Lloyd Free in a collision with Newlin. Free will miss the rest of the Houston series, and at least part of the finals—if the 76ers reach them.
