Wyndham Clark leads Rory McIlroy and Matt Fitzpatrick by one stroke after 36 holes at the Canadian Open

Wyndham Clark was able to hold onto his outright lead at the Canadian Open with an even par second round on Friday, one stroke ahead of Rory McIlroy and the chasing field.

Clark remains at seven under after a spectacular 63 on Thursday, posting three birdies and three bogeys on his second trip around the course.

McIlroy headlines the five-man group at six under, along with American trio Keith Mitchell, Jim Knous and Alex Smalley, as well as England's Matt Fitzpatrick, who closed his round with three consecutive bogeys to surrender the lead.

Alone at five under in outright seventh is Austin Cook, who posted Friday's round of the day with his six-under 64, going bogey-free with six birdies to vault himself into contention after entering play at one over.
