The Fairmont Heights girls basketball team, 2-18 last year, is 5-0 and enjoying one of its finest starts.

"I don't think we've been 5-0. This is our best start in a long, long time," said Hornets Coach Jeff Pieplow. "We are not great, but the kids are running and hustling. We have a lot of work to do and so far, but maybe I should be coach of the year on scheduling."

The Hornets, who did not participate in a Christmas tournament, have defeated Regina, Northwestern, Central, Forestville and Laurel; three of the teams have sub-.500 records.

Pam Wallace is averaging about 15 points per game and 6-foot-1 Paula Prince is the top rebounder for Fairmont Heights, which won the Maryland Class A state championship in 1983.

The Hornets girls junior varsity team is also off to a good start. Winless last year, the team is 2-2.

"We are rolling," said Coach Ralph Paden.

Pat Briscoe, who coached girls basketball, track and softball at Anacostia for the past 11 years, was named athletic director at the Southeast Washington school. Briscoe, a math teacher, replaces Allen Chin, who was named interim Interhigh League athletic director last month.

"My husband {Frank} will continue coaching the teams. With this new duty, I can't put too much time in coaching anymore," Briscoe said. "I'm wearing a different hat and I'll have more responsibility, but I think I'll enjoy it. The administration has given its support and offered help."
