Canadians Hadwin, Taylor off to tough starts at the Open Championship | TSN

The 152nd Open Championship is underway from Royal Troon in Scotland and an early start has not led to success for Canadians Adam Hadwin and Nick Taylor.

Taylor and Hadwin each finished the day 4-over in a tie for 78th at the conclusion of their rounds, while Corey Conners is 1-over through 13 holes. Mackenzie Hughes, the fourth Canadian in the field, is even-par through one.

American Justin Thomas surged into the clubhouse lead at 3-under with birdies on 17 and 18. Brooks Koepka is among the group of players just behind Thomas at 2-under after four straight birdies.

Rory McIlroy, who is looking to snap his major drought at 10 years, had a disastrous 7-over opening round, making two separate double-bogeys en route to a 78. Bryson Dechambeau, who topped McIlroy at the U.S. Open, also struggled in Round 1, finishing his day at 5-over. 

Pre-tournament favourite Scottie Scheffler and Tiger Woods are each on the course during their opening round. Track Tiger’s entire round here.
