Johnson shares 54-hole lead with 3 others at Canadian Open

Dustin Johnson sits atop a crowded leaderboard after three rounds at the Canadian Open, sharing the lead with Byeong Hun An, Kevin Tway, and Whee Kim - all at 17-under heading into Sunday.

Johnson carded the best round of the group, as his 65 Saturday at Glen Abbey Golf Club will put him in the final pairing alongside An for Round 4.

Tway, the leader after 36 holes, held his ground in the third round, shooting 4-under to hold the lead after 54 holes for the first time of his career.

The leaders have a four-shot lead over the field, with one glaring difference between them. An, Kim, and Tway are all searching for their first PGA Tour win, while Johnson is looking for his third this season alone.

Notables Tommy Fleetwood and Tony Finau both sit in a tie for 13th, six shots off the pace.

Mackenzie Hughes is the low Canadian heading into the final round after he birdied five of his final six holes, shooting 67 to come in at 11-under for the tournament.
