George Washington University golf coach Vern Caswell and his best player, Ken Dickler, played 2-under-par golf and defeated Gray Hamilton of Tantallon and Scott Inman of Springfield, 2 and 1, for the championship of the 38th Belle Haven Four Ball yesterday.

In their morning semifinals, the GW twosome eliminated Washington Redskins safety Greg Williams and his Chantilly partner, Northern Virginia Amateur champion Ken Newlin, 2 and 1.

"We didn't expect to get this far," said Caswell, 24, who plays out of Brooke Manor. "We came out here to have fun. We had a ball."

The most fun was watching Dickler, 22, of Cedarhurst, N.Y., who just graduated from GW and hopes to pursue a master's degree in accounting. Dickler, a straight-shooting, confident- looking player, was 2 under par on his own ball and rock-solid.

"He played well and he knew I could drive the cart," joked Caswell.

Dickler made an excellent shot from a greenside bunker at the 10th hole to maintain a 1-up lead. The GW group went 2 up at the 14th when Dickler made par. Hamilton prolonged the match by sinking a 20-foot birdie putt that tied the 16th hole. The match ended at the par-3 No. 17, where Caswell secured par after hitting his tee shot onto the green, 30 feet from the cup.

In the morning semifinals, Caswell and Dickler were even par in ousting Williams and Newlin. Inman and Hamilton eliminated qualifying medalists George Andre and Gray Tuttle on the second extra hole.

Williams, who plays on all Redskins special teams, combined with Newlin to beat two of the area's finest amateurs, Marty West and Gill FitzHugh, in Saturday's quarterfinals.

"It's tough to get up for Caswell and Dickler after you beat FitzHugh and West," said Caswell. "I think they had a letdown," said Dickler. "They never put any pressure on us."

Williams, who plays to a four handicap, will shortly closet his golf clubs and prepare for this week's Redskins minicamp.

In their semifinal, Inman and Hamilton took advantage of Andre and Tuttle's only bogey of the match on the second extra hole to win with par. Andre and Tuttle lost to Butch Mielke and Buddy Peoples in last year's final.

Brian Willard of Congressional and Randy Morris of Washingtonian defeated Vic Esola of Greendale and Kurt Marx, unaffiliated, to win the first flight.

In the second flight, Pat Tallent of Congressional and Mike Grant of Palm Beach, Fla., beat Steve Thomas and Scott Kimmel of Tantallon, 4 and 2. Third flight winners were Ted Till and Gary Clontz of Montgomery Village, who turned back Bob Harwick of Westwood and Wayne McGowan of Chantilly, 4 and 3.
