Golf-Garrigus grabs slender lead at Canadian Open

July 28 (Reuters) - Robert Garrigus grabbed a one-shot lead

as American players took a stranglehold on the Canadian Open

after the third round in Ontario on Saturday.

Garrigus fired a six-under-par 64 to move to 16-under 194,

one clear of William McGirt (66) and two in front of Scott

Piercy (67).

McGirt and Piercy had shared the lead overnight.

American players made up the top 10 players on the

leaderboard with former major winners Retief Goosen of South

Africa (63) and Fijian Vijay Singh (69) the best of the

international challengers, seven shots back.

Garrigus carded four birdies and an eagle on a bogey-free

day and promised to continue to attack on Sunday as he searches

for his second PGA Tour victory.

"It's foot to the floor as much as possible," he said. "I

know I can't let anybody in the golf tournament and if I go out

and make birdies they're not going to catch me so I'm just going

to go hammering at flags and hit fairways and hopefully

everything works out.

"I just like the way the course sets up. It's a hilly golf

course, fitness is a big issue and I'm in really good shape

right now so I'm loving where I am at."

Goosen rose 42 places into a tie for 11th with his

seven-under round. Scott Stallings and Chris Kirk matched his 63

and share fourth spot with fellow American Bo Van Pelt (67) on

198.

Kirk looked set to smash the course record of 62 at the

Hamilton Golf and Country Club after getting to seven under

through 10 holes but he parred the last eight.

David Hearn and Graham DeLaet were the best of the locals on

208, meaning Canada's victory drought in the tournament is

almost certain to be extended to 58 years.
