SOUTHPORT, England (AP) — Jackson Suber was one of three dozen players under par at the British Open when he made birdie and eagle in the blink of an eye and suddenly found himself atop the leaderboard at Royal Birkdale.He had never played links golf until three days earlier. Not only is this his first appearance in the British Open, it’s his first time in Europe. He still won’t get behind the wheel on the right side of the car because he jokingly said, “I’m trying to make it here for four days.”The first day was brilliant, a 5-under 65 that gave the unheralded American a one-shot lead going into the second round.Suber was initially holding his own Friday — a birdie on the second hole — before dropping three shots on another breezy day on the Birkdale links.The surprise first round leader is No. 115 in the world, and he is No. 81 in the FedEx Cup on the PGA Tour with three top 10s this year, one of which was a tie for fourth in the Canadian Open that got him into the field at Royal Birkdale for his third major championship.Where he goes from here is of interest. But this was not the first time that a leader at the British Open, or any major for that matter, has caused people to do a quick search for who he is.
