His front-running, three-shot victory in the Canadian Open yesterday was not quite as easy as it looked, Curtis Strange suggested.

"I seemed to coast home," Strange said at Glen Abbey Golf Club in Oakville, Ontario, after he had won this national championship and PGA Tour event a second time in three years. "But you don't do that. You don't ever coast home.

"I was standing on the 18th tee thinking, 'How can I lose a three-shot lead?' Now, that's not the kind of thing you want to be thinking about, but I did," Strange said.

The Virginian's worries were unfounded.

Strange broke out of a three-way tie for the lead on the first hole, birdied the second and compiled a solid, no-bogey, 3-under-par 69 over the last 18 holes for a course-record 276, 12 under for 72 holes.

There were two critical factors, he said.

"I was playing so well, driving so well, hitting the ball so well, my swing wouldn't let me choke. And nobody made a run at me."

Two would-be contenders self-destructed, Mike McCullough on a quadruple bogey-8 and David Frost on a couple of three-putt pars.

Strange, 32, acquired the 10th victory of his 11-year PGA Tour career. His score broke the Glen Abbey Golf Club standard set by Bruce Lietzke in 1982. His $108,000 from the total purse of $600,000 raised Strange's 1987 earnings to $397,860.

The win set up Strange as a likely favorite for this week's Anheuser-Busch Classic at Kingsmill near his home in Williamsburg. Strange serves as the tournament host.

Jodie Mudd and two South Africans, Frost and Nick Price, tied for second at 279.

McCullough opened the day in a three-way tie for the lead with Strange and Canadian hope Richard Zokol, and shared second until he pulled his second shot into deep rough above and to the left of the 14th green. It took him four shots to get out onto the putting surface and he took an 8 on the par-4.

McCullough did come back with birdies on 16 and 17 and, with a 74, tied for fifth at 281. Zokol closed 75 -- 282.

Senior PGA:

Bruce Crampton shot 5-under-par 67 and coasted to a six-stroke victory over Orville Moody in the $225,000 Greenbrier Seniors Championship at White Sulphur Springs, W.Va.

Crampton, who took control on the tournament's first day with a 63, completed the 54-hole event at 200, 16 under par to match the tournament record set by Don January in 1985, and took home $34,000. January, the two-time defending champion, tied with Lee Elder and Bobby Nichols at 209.

Gary Player shot a 65, for 210, as he and Charlie Sifford made the senior tour's first holes-in-one of the year.

LPGA:

Jane Geddes, sixth starting the day, shot 5-under-par 67 to beat rookies Nancy Taylor and Jill Briles by two shots in the $225,000 Jamie Farr Toledo Classic.

Geddes, 1986 U.S. Open and 1987 LPGA Championship winner, picked up $33,750 after finishing the four rounds at Glengarry Country Club at 280 and is No. 2 in LPGA season earnings with $292,547.

Taylor, who had held the lead after rounds one, two and three, lost it with a double bogey on the 365-yard 13th hole.

Briles birdied 13 and tied for the lead when Geddes bogeyed 17. But Briles bogeyed 15, and she and Taylor bogeyed 17 as the leaders played the final holes in steady rain.

Virginia Amateur:

Vinny Giles birdied the first two holes, then held on to capture his seventh state amateur championship, 1 up, as Steve Douglass of Norfolk missed a two-foot par putt on the 36th and final hole that would have evened the match.

With the victory on the Golden Eagle course in Irvington, Giles, at 44, is believed to be the oldest winner in the 74-year history of the event he had last won in 1971.

Irish Open:

Bernhard Langer fired a 4-under-par 68 to sweep to a 10-stroke victory, 269 to 279 for runner-up Sandy Lyle, at Portmarnock. Regaining a title he won in 1984, the West German earned $54,000.
