ANCASTER, Ontario (AP) - Scott Piercy shot an 8-under 62 on Thursday in the first round of Canadian Open, taking advantage of perfect scoring conditions at rain-softened Hamilton Golf and Country Club.

Piercy eagled the par-5 fourth and 17th holes and had five birdies and one bogey.

Greg Owen and William McGirt were a stroke back, and Robert Garrigus had a 64.

Ernie Els, the British Open winner Sunday at Royal Lytham & St. Annes, opened with a 72.

Jim Furyk, the winner in 2006 at Hamilton and 2007 at Angus Glen, shot a 70.
