FREDERICK, MD., MAY 28 -- Up until two weeks ago, the Frederick Keys had established themselves as the stronger of the two area Carolina League teams. However, after Prince William completed a three-game sweep of the Keys tonight with a 7-3 victory at Harry Grove Stadium, the third-place Cannons have won six straight and are just 2 1/2 games behind the second-place Keys in the Northern Division. The Keys have dropped six straight.

"We're a better ballclub than we had been playing earlier in the year," Prince William Manager Mike Hart said. "We're just starting to put the pieces of the puzzle together."

Jeff Motuzas provided most of the offense for Prince William (24-24) with a grand slam that capped a five-run fourth inning. Roger Burnett drove in Lyle Mouton on a groundout to tie the game at 1. Starter Kevin Ryan (2-4) walked Jason Robertson and Ramon Jimenez to load the bases, and Motuzas homered off the left field fence.

"I've been slumping a lot lately," Motuzas said. " . . . But I just went out and swung the bat today."

Prince William added two runs in the fifth to make it 7-1 before Frederick (26-21) countered with two in the eighth.
