Dustin Johnson has continued his incredible form with a 6-under 66 in the first round of the RBC Canadian Open.
Lead by another outstanding performance off the tee in which he averaged over 320 yards, while still managing to hit 71% of fairways, Johnson is tied first with fellow American, Luke List.
List used some stellar iron play to rocket to the top of the leaderboard after round 1.
Several Australians started nicely including World Number one and defending champion, Jason Day, who opened with a solid 3-under 69 to be tied 11th along with fellow Australian, Greg Chalmers.
Day at times struggled off the tee but helped by an eagle, 3 on the par-5 second (his 11th hole), he managed to grind out a nice opening round to be well placed for a Friday assault.
Day said in an interview with the PGA Tour that "it was tough out there with how dry everything is".
The World Number one also admitted to taking an "aggressive approach" to the round due to the "fast 'n' firm" nature of Glen Abbey Golf Club's greens.
Other Australians that seem poised to make the weekend rounds include Rob Pampling, Cameron Percy & Stuart Appleby after they all had a first round score of 1-under 71.
The second round commences tonight in Australia, with Dustin Johnson teeing of around 10pm AEST and Jason Day having to wait until early morning before he starts his second round.
