Brandt Snedeker carded a third-round 66 at Glen Abbey to take a one-shot lead into the final day of the Canadian Open.
The world number 23 leads on nine-under for the tournament courtesy of an eagle on the par-five 18th, taking him ahead of round-two leader and US Open champion Dustin Johnson at the top.
Canadian amateur Jared du Toit is also just one stroke behind Snedeker, having dropped three shots during Saturday's session which he soon made amends for by matching his rival with an eagle on the last hole.
Luke List, who had a joint-lead at the top for the opening two days, has slipped seven shots off the pace after a round of 77, while Scottish competitor Martin Laird's five birdies leave him in a tie for sixth on six-under.
