OAKVILLE, Ontario (AP) - Jason Dufner threatened to shoot in the 50s, then settled for a 9-under 63. Mark Calcavecchia made a PGA Tour-record nine straight birdies. And there were two more aces in perfect scoring conditions at the rainy Canadian Open.
Soon after Dufner finished the second round in light rain Saturday, heavy showers hit the already-saturated Glen Abbey course, forcing tour officials to postpone the third round until Sunday morning.
Dufner eagled the par-5 13th to reach 9 under for the round, but played the final five holes in even par - birdieing the par-5 16th, dropping a stroke on the par-4 17th and saving par on the par-5 18th after hitting into the water.
