Dustin Johnson cannot be stopped.
The 32-year-old fired an opening 6-under 66 on Thursday at the RBC Canadian Open, earning him a share of the first-round lead at Glen Abbey Golf Club. Luke List posted that same number earlier in the day, as he used a 5-under 32 to start to raise him to that 6 under number by the end of a bogey-free round.
But Johnson stole the show late.
Six birdies in 13 holes boosted the American to 5 under until a wicked drive left at the par-4 14th found the water and sent him reeling toward a double bogey.
