Tim Vigotsky of Reston and Greg Carpousis of Army Navy shot 72s over 6,423 yards of treachery known as Marlboro Country Club to share the first-round lead in the 54-hole Washington Area Amateur Champions golf tournament yesterday.

Vigotsky played in the day's first group, then left to play in a tournament at Kenwood. He birdied the 14th hole to get back to even par and parred in.

Carpousis played in the final group and birdied the 13th and 14th holes for a back nine score of two-under-par-5 17th, a hole that left most shaking their heads is dismay.

"It's the toughest hole I've ever played," said Glen Barrett of Pinecrest, who took eight shots there and had company when he failed to break 80. Gurney Jones of Hampton, Va., set the day's high score on the hole, a 13. The 17th is a 520-yard par-5 cut out of the woods. It requires a long tee shot to a small landing area, then a long second shot over water to set up an approach shot to an elevated green.

Bob Hawkins of Pinecrest, tied with Dave King and Wayne Foltz at 73, escaped the 17th with a well-earned 6.

The field of 107 will be cut to 75 after today's second round.
