In a game twice delayed by rain, Frederick scored two runs in the sixth to beat Prince William, 4-3, last night in the seven-inning first game of a doubleheader at Prince William County Stadium. That ended the Keys' four-game losing streak and tied them with the Cannons for the lead in the Carolina League's Northern Division with 8-11 records.

Todd Stephan (5-2), pitched three innings, giving up four hits, to gain the win. James Moody (2-2) was the loser.

Game 2 of the doubleheader was suspended by rain in the bottom of the first with Frederick leading, 1-0. It will be completed today at 6:30 p.m. before the regularly scheduled game. Both games will be seven innings.

In the first game, rain delay No. 2 came in the sixth inning, with Tyrone Kingwood left on first and one strike on Pete Rose. When the game resumed, the Keys took a 4-3 lead. Rose eventually sacrificed Kingwood to second. Mike Lehman singled to center, with Kingwood advancing to third and scoring on Ed Horowitz's RBI single to right. Mike Richardson's suicide squeeze bunt scored Lehman for the go-ahead run.

After rain delay No. 1, which interrupted the fifth inning, lasted 1 hour 48 minutes, Prince William scored two runs on three hits to take a 3-2 lead.

Paul Oster greeted Stephan (on in relief of starter Pat Leinen) with a triple to center and scored on Dave Silvestri's triple to right. One out later, J.T. Snow singled to score Silvestri.
