Justin Rose sets Torrey Pines pace with 62. Koepka makes his PGA Tour return with 73

SAN DIEGO (AP) — Justin Rose had birdie chances on all but one hole Thursday and turned that into a 10-under 62 on the easier North course at Torrey Pines, giving him a one-shot lead in the Farmers Insurance Open on a day that marked the return of Brooks Koepka from LIV Golf.

Koepka garnered so much of the attention under the brilliant sunshine along the Pacific Coast, the first PGA Tour member to leave for the Saudi-funded rival league only to get out of his contract with one year left and be allowed to return.

Koepka didn't make a birdie until his final hole on the tougher South course for a 1-over 73 and was happy to get that first round behind him.

“From the first tee on, it was great. It actually made me settle down a little bit,” Koepka said. “Like I said, it made me feel good just to be out here.”

Rose missed the cut in his 2026 debut in The American Express last week. While the North course is easier, his game was sharp. Even without birdies on two of the par 5s, he still posted a great score before he heads to the South.

Justin Lower, on edge with his wife at home about to give birth to twins, had a 63 on the North. Hideki Matsuyama and Max Greyserman each had a 64.

Seamus Power had the low score at 65 on the South course, which has hosted two U.S. Opens and played to an average score of 72.482. The average score on the North was 69.139. Of the 22 players at 67 or lower, only Power and Max McGreevy (66) were on the South.

“North Course clearly is one that you want to try to make the most of and it’s great to do that today for sure,” Rose said.

He made par from the fairway on his closing hole at the par-5 ninth, finding a bunker, blasting out to about 4 feet and missing the birdie putt. But he only scrambled for once, on the 451-yard 14th hole and kept a clean card.

Lower lost his full card last year when the PGA Tour reduced full status to the top 100 on the FedEx Cup, down from 125 in previous years. Lower got into Torrey Pines because of the 147-man field over two courses, so this about making the most of an opportunity.

And what a time. He already has a 3-year-old. Now his wife is about to deliver twins.

“If I’m being really truthful with everyone, my mind’s not really here,” Lower said. “My wife is 34 weeks pregnant with twins and I’m just trying to get home on Monday to try to help everything out as much as I can. Luckily we have family close and everything. Yeah, she’s going through it right now. Life’s about to get real if it wasn’t real already.”

Xander Schauffele, who was born across the road from Torrey Pines, played for the first time since he won in Japan last fall. He has the longest active cut streak at 72 and was on the ropes early on the South, 3 over for his round through 11 holes.

But he made birdie from a fairway bunker on the 12th hole, hit the pin with a shot from the back bunker to set up birdie on the par-5 13th and ended his round with a chip that struck the pin on the 18th when it the golf ball was rolling at flag speed.

It added to a 73, just above average considering how hard the South played.

“I was happy with the fight,” Schauffele said. “But I only hit three fairways, and the North course also is hard from the rough. Any of those guys at 8 or 9 under on the North are hitting more than two or three fairways.”

And with that he was off to the range.

Koepka said he was nervous on the first tee on the South, not knowing what kind of response he would get from the crowd after defecting to LIV Golf. He hit a 301-yard drive and an approach to 10 feet, two of his best shots of the way.

But his birdie chances were limited — certainly not as many as Rose on the North — and he was 1 over on the par 5s until an 8-foot birdie putt on the last hole.

He looked forward to the next three days. That starts with getting to the weekend.

WASHINGTON (AP) — President Donald Trump on Thursday threatened Canada with a 50% tariff on any aircraft sold in the U.S., the latest salvo in his trade war with America’s northern neighbor as his feud with Prime Minister Mark Carney expands.

Trump’s threat posted on social media came after he threatened over the weekend to impose a 100% tariff on goods imported from Canada if it went forward with a planned trade deal with China. But Trump’s threat did not come with any details about when he would impose the import taxes, as Canada had already struck a deal.

In Trump’s latest threat, the Republican president said he was retaliating against Canada for refusing to certify jets from Savannah, Georgia-based Gulfstream Aerospace.

Trump said the U.S., in return, would decertify all Canadian aircraft, including planes from its largest aircraft maker, Bombardier. “If, for any reason, this situation is not immediately corrected, I am going to charge Canada a 50% Tariff on any and all Aircraft sold into the United States of America,” Trump said in his post.

Trump said he is “hereby decertifying" the Bombardier Global Express business jets. There are 150 Global Express aircraft in service registered in the U.S., operated by 115 operators, according to Cirium, the aviation analytics company.

Spokespeople for Bombardier and Canada’s transport minister didn’t immediately respond to messages seeking comment Thursday evening.

The U.S. Commerce Department previously put duties on a Bombardier commercial passenger jet in 2017 during the first Trump administration, charging that the Canadian company was selling the planes in America below cost. The U.S. said then that the Montreal-based Bombardier used unfair government subsidies to sell jets at artificially low prices.

The U.S. International Trade Commission in Washington later ruled that Bombardier did not injure U.S. industry.

Bombardier has since concentrated on the business and private jet market. If Trump cuts off the U.S. market it would be a major blow to the Quebec company.

Treasury Secretary Scott Bessent warned Carney on Wednesday that his recent public comments against U.S. trade policy could backfire going into the formal review of the U.S.-Mexico-Canada Agreement, the trade deal that protects Canada from the heaviest impacts of Trump’s tariffs.

Carney rejected Bessent’s contention that he had aggressively walked back his comments at the World Economic Forum during a phone call with Trump on Monday.

Carney said he told Trump that he meant what he said in his speech at Davos, and told him Canada plans to diversify away from the United States with a dozen new trade deals.

In Davos at the World Economic Forum last week, Carney condemned economic coercion by great powers on smaller countries without mentioning Trump’s name. The prime minister received widespread praise and attention for his remarks, upstaging Trump at the gathering.

Besides Bombadier, other major aircraft manufacturers in Canada include De Havilland Aircraft of Canada, which makes turboprop planes and aircraft designed for maritime patrols and reconnaissance, and European aerospace giant Airbus. Airbus manufactures its single-aisle A220 commercial planes and helicopters in Canada.

During the Biden administration, the U.S. International Trade Administration touted the interdependence of the U.S. and Canadian aerospace industries and cited a 1980 World Trade Organization agreement that the website of the current U.S. trade representative says “requires signatories to eliminate tariffs on civil aircraft, engines, flight simulators, and related parts and components.”

Canada’s Trade Commissioner Service describes the United States as the largest trading partner for the country’s aerospace and space industries and the destination for a significant portion of exported aircraft, components and space technologies.
