McDowell immediately surrendered his narrow overnight advantage with an opening-hole bogey and had to scramble to save par at both the fifth and sixth, before holing a 20-footer at the par-three eighth.

The Northern Irishman dropped a shot at the ninth after finding the bunker with his approach to reach the turn tied with Dubuisson, who mixed two birdies with two bogeys on his front nine.

McDowell responded by draining a 20-footer at the next and striking a stunning approach at the 15th to three feet to set up another birdie, pulling him three clear of clubhouse leader Pieters.
