Rod Pampling has done best with a round of I under 69 but, after an eagle and a birdie at his opening two holes, he may well have been expecting something significantly better.
Pampling pitched in from just under 100 yards at his first hole (the 10th of the Hamilton Golf and Country Club’s layout) and all but holed his approach from much longer range at the next before, unable to maintain the fast start, eventually finished with 69 and a share of 59th place.
Pampling has yet to make a cut in twelve starts on the PGA Tour in 2019 and so while he is well back after day one it was a more encouraging start for him.
Curtis Luck recorded a round of 71 to be at 1 over and in a share of 105th and so already has a lot of work to do tomorrow to make what already appears to be an under-par cut.
Cameron Davis is even further back after his round of 73.
Keegan Bradley leads after day one, an opening round of 63 leaving him one clear of a group of five players namely Shane Lowry, Sungjae Im, Nick Taylor, Erik Van Rooyen and Roberto Castro.
Bradley has recorded only one top ten in 14 starts in 2019 and has missed two of his last three cuts but he has recorded several very low rounds in this event in the last few years and although not at this venue he appears to enjoy playing north of the US border.
Five consecutive birdies in the middle of his round set up the low score and he gets the chance to continue his good record in Canada as the week progresses.
It was not a great day for the pre-tournament favourites, Dustin Johnson (71) and Brooks Koepka (70), while Rory McIlroy improved from his missed cut at the PGA with a round of 67.
The leading three players inside the top ten at week's end and not already exempt to the Open Championship at Royal Portrush earn the right to play in that event.
