PRO BASKETBALL—While Boston and Philadelphia were racing down to the wire in the Atlantic Division (page 76), Chicago ended the regular season as a team on fire. The Bulls extended their winning streak to eight with victories over Detroit (109-103), Cleveland (121-108), Atlanta (108-83) and, finally, Indiana (101-97) to edge the Pacers for second place in the Central Division behind Milwaukee. With San Antonio firmly emplaced as the Midwest Division champion and Phoenix on top of the Pacific, Houston, Golden State and Kansas City played musical chairs on the final day of the season for the last two Western Conference playoff berths. The Rockets clinched their spot despite a 135-109 loss at San Antonio. In that game Houston's Calvin Murphy went 4-for-4 from the line, for an NBA season-record .958 free-throw percentage (206 of 215), surpassing the .947 (160 of 169) shot by Rick Barry in 1978-79.

Wayne Gretzky was held to two assists in Edmonton's 7-2 loss to the Bruins, as he was once again doggedly covered by Boston's Steve Kasper. In four games this season, Kasper has held Gretzky to one goal and three assists. Gretzky matched those totals in the Oilers' next game, a 7-2 triumph at Hartford, in which Glenn Anderson had a hat trick. Another assist, in a 4-2 victory over Detroit, gave Gretzky 152 points on the season to tie the NHL record set by Phil Esposito in 1970-71. With four games to play, Gretzky's 99 assists put him within reach of another mark from the 1970-71 season: the 102 assists amassed by Espo's teammate Bobby Orr.
