Sam Burns, Brooks Koepka headline six-way tie atop RBC Canadian Open

Brooks Koepka, Sam Burns, Emiliano Grillo, Sahith Theegala, Eric Cole, and Matthew Anderson all opened with 6-under 64s to share the first-round lead at the RBC Canadian Open at TPC Toronto's Osprey Course. Koepka sparked his round with four birdies over his final five holes, including key putts on holes 14, 17, and 18. Eric Cole, currently ranked 63rd in the world, needs a strong finish this week to break into the top 60 and earn an exemption into next week's U.S. Open at Shinnecock Hills.
