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 sun-baked Glen Abbey. He rebounded with six birdies and had a late bogey for a 1-under 71.
“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 nicely from 14 on in.”
Johnson played in the morning after eagling the par-5 18th late Thursday afternoon for a 66.
List also shot a 71, birdieing the par-5 16th and 18th after making three bogeys during a four-hole stretch early on the back nine.
“Real happy the way I finished up,” said List, winless on the PGA Tour. “It was kind of a battle the middle of the round there and definitely pleased with the way I finished on the two easy par 5s.”
Amateur Jared du Toit, former Arizona State teammate Jon Rahm, and Kelly Kraft were a stroke back, also shooting 71 apiece.
Du Toit made the turn tied for the lead at 7 under, then had a triple-bogey 8 on No. 2 and a bogey on No. 5. The Sun Devils senior birdied the next three holes and closed with a par.
“Taking an 8 always hurts, but I just kind of stayed patient,” du Toit said. “The putter heated up at the right time, and it was all good. Nothing but good things to say.”
Rahm is making his fourth start since turning pro after the U.S. Open. The Spaniard eagled the 16th hole.
Ricky Barnes (68), Ben Crane (70), Tyler Aldridge (70) and Brendon de Jonge (71) were 5 under.
Top-ranked golfer and defending champion Jason Day was 1 over, following his opening 69 with a 76.
UL International Crown
Lexi Thompson and Cristie Kerr helped the United States rebound in the UL International Crown.
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 of the LPGA Tour event.
The U.S. almost got a sweep, but Gerina Piller and Stacy Lewis each missed a birdie putt on 18 and had to settle for a single point against Moriya Jutanugarn and Pornanong Phatlum.
British Senior Open
Joe Durant birdied the par-4 18th hole for a 3-under 68 and a share of the Senior British Open lead with Kohki Idoki.
The 52-year-old Durant birdied three of the first five holes on the back nine, the second two on the par-5 12th and 14th at Carnoustie Golf Links, in 10-15 mph wind with some light rain.
Actor Jack Wagner had five birdies in a 27-point round to take a three-point lead over ex-hockey player Mike Modano (Westland) in the American Century Championship.
Michigan coach Jim Harbaugh had minus-8 points. Charles Barkley was last in the 84-player field at minus-36. Blair O’Neal led the five women in the field with eight points.
