Wyndham Clark holds one-shot lead at RBC Canadian Open

TORONTO (AP) — Wyndham Clark started the week with a late charge to play his way into the U.S. Open in a qualifier, and then he stayed hot Thursday in the RBC Canadian Open for a 7-under 63 to take the first-round lead.

Clark opened with five birdies in nine holes and kept bogeys off his card at St. George's Golf and Country Club for the third round of his PGA TOUR career at 63 or lower.

Matt Fitzpatrick was a stroke back, and Doug Ghim and Harold Varner III followed at 65.

Defending champion Rory McIlroy had six birdies in his round of 66 that left him tied with Tony Finau, Lee Hodges and Mackenzie Hughes, who would love nothing more than to become the first Canadian to win his national open since 1954.

McIlroy had to wait three years to defend his title because of the COVID-19 pandemic that canceled golf's fourth-oldest championship the last two years. He closed with a 61 to win by seven shots at Hamilton.

“I felt like the course was there to go even lower just from the rain and how receptive it was,” McIlroy said. “Overall, very happy with the start of the week, especially coming off a disappointing weekend at the Memorial last weekend.”

Clark didn't break par over the final three rounds at the Memorial, and he wasn't looking good in his 36-hole qualifier on Monday. But then he put together five birdies in an 11-hole stretch that allowed him to get into the U.S. Open next week at The Country Club outside Boston.

“It's nice to see some putts go in,” Clark said. “I haven’t shot a low one in a while. I’ve had a lot of couple under par, 3-, 4-under pars in my last few events, but really felt like I left a lot of shots out there. This round I maximized pretty much everything out there.”

Clark putted for birdie on all but one hole, and he holed an 8-foot par putt on No. 12 early in his round.

Fitzpatrick started and finished his round with a birdie, holing a 35-foot putt on the par-3 eighth hole for a 64.

"Really, really happy with the way I played today, just solid all around," Fitzpatrick said. “Had a couple opportunities to chip it a little bit closer, but other than that, I’m being really picky. Everything in my game was going well.”

PGA champion Justin Thomas, who wanted to play the week before a major because it worked so well the last time, opened with a 69.

Sam Burns, coming off a victory two weeks ago at Colonial, opened with a 67 in the afternoon, and top-ranked Masters champion Scottie Scheffler had a 69. The Canadian Open has attracted five of the top 10 players in the world.
