The Bullets, with four players scoring 20 or more points, blitzed previously unbeaten Bata Shoes, 141-122, in the Urban Coalition Summer Basketball League yesterday at Dunbar High School.

The Bullets, with a 5-0 record, won top seeding in the playoffs next week.

With Kevin Grevey (23 points) providing the outside scoring and second-round draft pick Ricky Mahorn (27) supplying the muscle inside, the NBA entry increased a 30-28 first-quarter lead to 64-54 at the half.

But it was Wes Matthews, the Bullets' first-round draft pick from the University of Wisconsin, who provided the most excitement for the standing-room-only crowd of 3,500. When the 6-foot-1 guard wasn't making look-the-other-way, between-the-legs passes to open teammates for uncontested dunks, he was picking off passes and soaring in for his own monstrous dunks that often resulted in three-point plays. He totaled 25 points, 14 assists and five steals.

Still, Bata Shoes (8-1) fought back from 26 points down in the third quarter to 110-99 with four minutes remaining.

Bullet free agent Ken Dancy (20 points) reeled off eight straight points in the next two minutes to put the game away.

Bata guard Enos Hill led all scorers with 29 points on a combination of long jumpers and quick spurts to the basket. James Green had 24 for the losers, playinga without leading scorer Mike (Hawkeye) Daniels.
