Long-hitting Tony DeLuca of Chantilly matched International's difficult par of 71 and won the medal by one stroke in qualifying for the District Amateur golf championship yesterday.

"He gained 30 pounds and 30 yards off the tee since he won the Northern Virginia Amateur," said Rob Black, who lost in the District final last year to Wayne DeFrancesco. DeFrancesco is playing in the Southern Amateur this week and is not defending here.

"When Tony catches the ball flush, God knows how far it goes," Black said. "He averages about 280 to 290 yards off the tee."

DeLuca, 19, who will be a sophomore on the Uni-ersity of florida golf team, sank a 30-foot putt to birdie the second hole but his three other birds were on putts of five feet or less.

"I hit some good iron shots. The par-3s here are extremely tough," DeLuca said. Especially brutal were the 213-yard fourth hole and 193-yard 17th, lined by woods with difficult pin positions.

"The course is in good shape, but the fairways are too long. There's no way you can hit a shot at the pin with spin on it with the fairway grass that long," said tblack, who birdied the first hole and was among five playoff winners for the final qualifying spots among 13 who shot 77.
