Robert Garrigus broke the 54-hole scoring record at the RBC Canadian Open that was set more than a half-century ago by Arnold Palmer.

Now he’ll try to win the same tournament where Palmer recorded his first career victory.

Garrigus shot a 64 Saturday and leads by one at 16 under through three rounds at a rain-softened Hamilton Golf & Country Club.

In 1955 at Weston Golf & Country Club, Palmer’s three-day total was one stroke higher.

A shot back of Garrigus is William McGirt, who shot 66, while Scott Piercy is two off the pace.

Scott Stallings, Chris Kirk and Bo Van Pelt are all 12 under.
