OAKVILLE, Ontario — Dustin Johnson started and finished the day tied with Luke List for the Canadian Open lead. The U.S. Open champion had to make up a lot of ground to do it.
Johnson had a double bogey and two bogeys on his first holes Friday in windy conditions at Glen Abbey. He rebounded with six birdies and had a late bogey in 1-under 71 to move to 7-under 137.
"I really don't know what happened the first four holes," he said. "Just got off to a bad start. Hit it in a couple awkward spots. Made some bad bogeys but fought back and turned it around and felt like I played really nicely from 14 on in."
Johnson played in the morning after eagling the par-5 18th late Thursday for 66.
List also shot 71, birdieing the par-5 16th and 18th after making three bogeys in a four-hole stretch early on the back nine.
Canadian amateur Jared du Toit, former Arizona State teammate Jon Rahm and Kelly Kraft were a stroke back, also each shooting 71.
Top-ranked defending champion Jason Day was 1 over, following his opening 69 with 76.
SENIOR BRITISH OPEN: Joe Durant birdied the par-4 18th for 3-under 68 and a share of the lead with Kohki Idoki (67) at 7-under 137 in Carnoustie, Scotland. Olin Browne (66), Jesper Parnevik (68), Carlos Franco (69), Tom Byrum (69) and Peter Fowler (69) were a stroke back, Mark O'Meara (70) topped the group at 5 under. First-round leader Woody Austin shot 74 to drop into a tie for 18th at 2-under 142.
LPGA: Lexi Thompson and Cristie Kerr helped the United States rebound in the International Crown in Gurnee, Ill., and Melissa Reid had a gutsy effort for England after her ill partner was sidelined. Thompson and Kerr routed Thailand's Ariya Jutanugarn and Porani Chutichai 4 and 3 for the Americans' first two points after they were shut out in the first session. With Charley Hull sidelined by a fever and complications from asthma, Reid was all alone for her four-ball match against Japan's Haru Nomara and Mika Miyazato. Reid took it all the way to 18, where Nomura made a matching birdie to close out a 1-up win. England leads Pool B with five points. Thailand and Japan were tied for second at four, and the United States was last with three. Taiwan tops Pool A with six points, followed by South Korea (four) and Australia and China (three each).
