Mike Glenn, usually a reserve with the Atlanta Hawks, had more than his usual allotment of playing time last night in Atlanta, and ended up with more than his usual allotment of points.

"It was the most minutes I've played all year, but I've kept my body ready," the 6-foot-3 guard said after coming off the bench to score 19 points in 29 minutes of play as Atlanta beat the league-leading Philadelphia 76ers, 102-97.

The victory gave the Hawks sole possession of fifth place in their battle with New York and Washington for the final two berths in the NBA's Eastern Conference playoffs. They are a half-game ahead of the Knicks and a full game in front of the Bullets.

Atlanta plays at Kansas City tonight and winds up its regular season as host to Milwaukee Saturday.

Glenn made six of his 11 shots--all from long range.

"I thought the key to the game was Mike Glenn's second half," Hawks Coach Kevin Loughery said. "He really picked us up. It was a highly emotional win."

The emotion was visible to the officials, who called 10 technical fouls, including a pair against 76ers Coach Billy Cunningham, who was ejected from the game in the third period.

Dominique Wilkins of the Hawks had 26 points, including the bucket that put Atlanta ahead for good late in the fourth quarter.
