OAKVILLE, Ontario — Dustin Johnson made a 10-foot eagle putt on the par-5 18th hole Thursday for a 6-under 66 and a share of the Canadian Open lead with Luke List.

The U.S. Open champion set up the eagle with a 364-yard drive and 150-yard approach. In windy conditions at sun-baked Glen Abbey, Johnson also had seven birdies and drove into the water on the par-4 14th en route to a double bogey. Johnson played the three back-nine par-5 holes in 4 under.

List birdied all four par 5s in a round he closed with seven pars.

Canadian amateur Jared du Toit was a stroke back along with former Arizona State teammate Jon Rahm, Chesson Hadley and Kelly Kraft. Coming off his junior season for the Sun Devils, du Toit holed out with an 8-iron for eagle on the par-4 17th and birdied 18.

Brandt Snedeker, the 2013 winner at Glen Abbey, had a 68 to match Brendon de Jonge, Steve Wheatcroft and Cameron Tringale.

Top-ranked defending champion Jason Day was in the group at 69.

Garrett Rank, the Canadian amateur who works as a professional hockey referee, also opened with a 69.

“I like this golf course,” said Johnson, ranked second in the world. “I think it sets up well for me. I like it off the tee. The conditions are really tough right now. The greens are really firm, but they are rolling really nicely. So if you get some good looks at it, you can hole some putts.”

LPGA: The United States lost both of its four-ball matches to England, and Yani Tseng helped Taiwan sweep Australia in the opening session of the UL International Crown at Gurnee, Ill.

Lexi Thompson and Cristie Kerr lost 2 and 1 to Holly Clyburn and Jodi Ewart Shadoff, and Stacy Lewis and Gerina Piller fell to Charley Hull and Melissa Reid by the same score. Thompson, Kerr and Lewis also were on the American team that was swept on the first day of the inaugural event in 2014 and finished sixth.

CHAMPIONS TOUR: Woody Austin made four birdies in a six-hole stretch on the back nine and finished with a 4-under 68 to take the first-round lead in the Senior British Open at Carnoustie, Scotland.
