Barry McCarty of Belle Haven eagled the 14th hole, birdied the 16th and went on to card 73 for a three-shot victory with 223 for 54 holes in the Washington Area Amateur Champions golf tournament yesterday at Marlboro Country Club.

Second round leader Dave King of Bethesda and chief challengers Tony DeLuca of Chantilly and Henri deLozier of Columbia, in the foursome behind McCarty's and demanding most of the attention, all self-destructed on the treacherous wood-lined course where water comes into play on all but four holes.

King shot 81, DeLuca 77 and deLozier 85, including a 10 taken with good humor on the 17th hole.

"I didn't think they were capable of blowing up like they did," said McCarty, who just graduated with a degree in business finance from Virginia Tech.

They were this day. On the 17th all in the final foursome hit atrocious drives. DeLozier, Glenn Barrett and DeLuca drove far to the right, into a water hazard. King pulled his drive to the left and hit a tree.

King, leading by three strokes heading into yesterday's play, opened with double bogey, bogey, bogey on the first three holes. DeLozier took a one stroke lead with back-to-back birdies on holes five and six.

DeLozier then suffered double bogeys on the eighth and ninth holes and never threatened again.

Then it appeared to be a battle between King and long knocker DeLuca.

DeLuca took a one-shot lead on the par-5 No. 13 when King hooked his second shot into a lateral hazard and took double bogey as DeLuca parred.

Just before torrential rains hit, McCarty made eagle on the 14th with a drive, a seven-iron and long putt to pull even with DeLuca and King at six over par for the tournament.

After a 1 1/2-hour rain delay, DeLuca appeared to be in command when he took a two-stroke lead on the par-3 No. 15 with a birdie while King bogeyed and McCarty, playing in the next group, also bogeyed.

DeLuca then came unwound with double bogeys on the next two holes. King parred the 16th hole but took bogey 6 on the 17th.

Needing a birdie to tie McCarty on the last hole, King pulled his drive left, then pulled his second shot into high weeds and took double bogey 6.

For everyone but McCarty, the Marlboro course, known as "The Duke," was the winner, hands down.
