The wind caught just about everyone off guard Thursday in the British Open. It came from the opposite direction off the Irish Sea, accompanied by occasional rain, and made Royal Troon a tougher test than anyone was expecting.

It wasn't even the biggest surprise.

Daniel Brown made his major championship debut a memorable one. He birdied two of the last three holes for a 6-under 65, giving him a one-shot lead over Shane Lowry with just enough spectators left in the Scottish twilight to celebrate his amazing day.

It was getting too dark to take a photo of his name atop the leaderboard, and that doesn't interest the 29-year-old from England, anyway.

"I'm going to try and keep my feet on the ground a bit and take on the job again tomorrow," Brown said.

A one-time winner on the European tour, he arrived at Royal Troon having failed to make the cut in seven straight tournaments dating to March until a couple of good events. One was the final qualifying to earn a spot in his first major, the other at the Scottish Open when he made the cut and finished 61st.

However, Thursday was all about the wind – yes, it was fierce, but it was different. Instead of players trying to make a score on the downwind front nine and keep it together on the way back, it was tough from start to finish.

Rory McIlroy certainly found that to be the case. He shot 78 with a pair of double bogeys. Ditto for U.S. Open champion Bryson DeChambeau, who went out in 42 on his way to a 76. Every major is tough on 48-year-old Tiger Woods, who had a 79 for his highest start in a major since an 80 in the 2015 U.S. Open at Chambers Bay.

Lowry motored along, putting as well as he has all year, soaking up the warm applause all while reminding himself it was only a good start and three more rounds were ahead of him. But he sure knew what to expect.

"Fortunately enough, I came here two weeks ago and I played this wind on the second day that I played here. I saw the golf course in every wind possible I could see it," Lowry said. "Yeah, I guess that was a good thing to do, and it's out there paying off a little bit today."
