Tour sophomore Nolan Henke, who missed the cut in five of his last eight tournaments, made birdie putts on the 16th and 17th holes yesterday for a 5-under-par 66 and tied Jim Hallet for the first-round lead of the B.C. Open in Endicott, N.Y.

Hallet, who has only one top 10 finish this year, made a 10-foot birdie on his final hole for his 66 on the 6,966-yard En-Joie Golf Course. Hallett played a steady round with five birdies despite afternoon winds of up to 15 mph that made driving difficult on many of the narrow fairways.

Chasing the leaders were Clark Burroughs, Johnny Miller Jr. and Emlyn Aubrey, all at 67.

World Matchplay: Britain's Ronan Rafferty inflicted the worst defeat Severiano Ballesteros has suffered in 15 appearances in this event when he thrashed the Spaniard, 8 and 6, in the first round at Wentworth, England.

Rafferty scorched Wentworth's 6,945-yard West Course in a record 62 in the morning for a six-hole lead, then wrapped it up with a 12-foot putt on the 12th hole in the afternoon.

PGA champion Wayne Grady of Australia came from four down after 15 holes to defeat Bernhard Langer of West Germany, 4 and 2, and Chip Beck of Fayetteville, N.C., ousted Japanese rookie Ryoken Kawagishi, 4 and 3.

MBS LPGA Classic: Janet Anderson had the third hole-in-one of her career but shared the first-round lead with Cathy Morse, who hit all 18 greens in regulation, at 4-under-par 68. Anderson's 6-iron drive on the 149-yard 16th of the 6,351-yard Los Coyotes Country Club in Bueno Park, Calif., landed a few feet short and rolled in.

Defending champion Nancy Lopez, Nancy Brown and Sarah McGuire were one stroke back.

Gene Sarazen Jun Classic: In Shioyacho, Japan, Australians Anthony Gilligan and Wayne Smith each shot a 66 and shared a two-shot lead after the opening round of the $536,000 event.
