Oxon Hill, held scoreless in a sluggishly played first half, turned up the intensity and rallied for 20 second-half points to defeat Crossland, 20-3, in a Prince George's AA League game last night at Friendly.

The Cavaliers (1-1), who had taken an early 3-0 lead on a Kamal Tyson field goal, were setting up for another field goal attempt when controversy developed.

With four seconds left in the half, Tyson's field goal attempt was blocked, and the loose ball was scooped up by Oxon Hill's Brian Edwards, who ran for an apparent touchdown. But referee David Pulaski blew the play dead.

After a lengthy debate, the play was called back and the Clippers' touchdown was nullified. The ball was brought back to the original line of scrimmage, and the down replayed. Crossland then elected to attempt a fake, but the play was stopped and the half ended.

However, the disappointment of having their touchdown nullified served as a wake-up call for the Clippers, who opened the second half with renewed enthusiasm.

"There's no question that call changed the momentum of the game around," said Oxon Hill Coach Mike Pearson. "I just told the guys {at halftime} to go out and go after them. They weren't playing up to par up to that point."

With the call still weighing heavily on their minds, the second half belonged to the Clippers. And it didn't take long for them to atone for their scoreless half.

Crossland, which struggled offensively throughout the second half, fumbled on its first drive, turning the ball over at its 44. Six plays later, Darren Huckaby scored on a six-yard run to put the Clippers in front, 7-3.

In the fourth quarter, the Clippers began to break it open. Oxon Hill linebacker Fred Bryant hit Crossland quarterback Mike Jones just as he was releasing a pass, tipping the ball into the air. The Clippers' Kenny Ford caught it and returned the interception 25 yards for a score.

A three-yard touchdown run by Oxon Hill's Tim Jones late in the game capped the scoring.

"I thought we played pretty well in the first half, but Oxon Hill had the momentum after the call," said Cavaliers Coach Larry Layman. Crossland (1-1) 0 3 0 0 3 Oxon Hill (1-1 0 0 7 13 20
