SOUTHAMPTON, N.Y. — Ryder Cowan knew he was playing good golf coming into the U.S. Open.Midway through his round Thursday, the leaderboard showed that the amateur was playing the best golf of anyone at Shinnecock Hills.Cowan, a 21-year-old who will be a senior at Oklahoma, briefly held the lead in his first major championship before finishing with a 2-under 68, matching the lowest round by an amateur at Shinnecock. He was tied for second when the first round was suspended because of darkness.“Through nine, I looked up and I was 3-under par,” Cowan said. “I definitely looked at that leaderboard, and I saw it up there.”A couple bogeys on his second nine knocked him back, but with the sun setting, Cowan finished strong shortly before play was stopped for the day. Playing the ninth hole, he hit his approach to 5 feet and knocked in the putt for his fourth birdie of the round. Starting on the back, he had three of them in his first eight holes, moving to 3-under and into the lead after his birdie at the par-3 17th.“I feel like I started well. I got some momentum from that,” Cowan said. “I knew, if I could get through those holes, I had a couple easy holes coming in.”I hit it good all day, put myself in good positions throughout the day. Cowan was four shots behind Wyndham Clark, in position to be the first amateur to finish a U.S. Open round in the top five since Brian Campbell was tied for fourth after the first round in 2015. The group he is tied with includes past U.S. champions Dustin Johnson, Matt Fitzpatrick, Gary Woodland and Jon Rahm.
