Theegala among handful of co-leaders at 6 under after opening round of RBC Canadian Open

Five golfers stormed up the leaderboard to join Sahith Theegala in a six-way tie for first after one round of the RBC Canadian Open.

Theegala fired a 6-under 64 during the morning wave at TPC Toronto to take the first-round clubhouse lead and then Emilliano Grillo, Eric Cole, Brooks Koepka, Sam Burns and Matthew Anderson of Mississauga, Ont., matched that performance in the afternoon.

Adam Svensson of Surrey, B.C., was in a nine-way tie for second, a shot back of the leaders.
