Billy Knight had 30 points and rookie Clark Kellogg scored 23 last night in Philadelphia to lead the Indiana Pacers to a 117-108 victory over the previously unbeaten 76ers.

It was Philadelphia's first loss in seven games this season and was Indiana's first victory in Philadelphia since April 7, 1978. Since then it had lost 11 in a row at the Spectrum.

Indiana trailed, 32-22, late in the first quarter, but went on a 17-2 spurt and led, 39-34, on Knight's jumper with 8:55 remaining in the second period. Indiana increased its lead to 67-53 at 9:53 of the third quarter, but Julius Erving took the 76ers on a 24-6 run that led to a 79-73 lead on Andrew Toney's field goal with 2:12 remaining in the period.

Clem Johnson scored eight of Indiana's first 12 points in the fourth period and the Pacers took a 98-89 edge on two free throws by Kellogg with 7:37 left to play.

A three-point play by Bobby Jones brought the 76ers to within 103-99 with 5:13 remaining, but the Pacers scored six straight points and never again trailed.

The 76ers committed 31 turnovers to only 16 for Indiana.
