Tour rookie Harris English and Greg Owen have both qualified the Open at Royal Lytham & St Annes in July.
English, a PGA Tour first year professional, dominated the 36-hole qualifying tournament at the Gleneagles County Club Queens Course at Plano, near Dallas.
He shot an incredible course record 10-under-par before following up with a second round 63 to secure his place at the Open on July 19-22.
English's 60 was the lowest 18-hole qualifying score since the Royal and Ancient began staging qualifying in the United States in 2004.
He beat Mansfield-born Owen by four - with his run seeing him hole six successive birdies
And English later told the official Open site: "I kind of lost track of how many I made.
"I was relaxed. I had some fun. I was striking the ball really well. In fact, I was doing everything really well.
"I knew the wind wasn't going to be blowing, so I knew the scores were going to be low. I couldn't let up.
"I decided to keep the pedal to the metal on the last 18 holes, where I left myself in really good position to make putts.
"It's awesome. I told my parents and my agent that I really, really wanted to play in the British Open, so I came here today with that goal - and here I go."
English and Owen will be joined by the other finishers inside the top eight - Sweden's Daniel Chopra, Canada's Stephen Ames, Argentina's Andres Romero and Americans Justin Hicks, James Driscoll and Bob Estes.
English, 22, from Georgia, who played in the amateur Walker Cup in Aberdeen last September, shot six successive birdies from the third to turn in 29, eagled the 10th and then added further birdies at the 12th and 18th.
Following the first round Chopra had been joint second along with Americans Tommy 'Two Gloves' Gainey and Michael Thompson but only the Swede kept his spot in the top eight.
Chopra's compatriot Henrik Stenson, third in The Open in 2008 and 2010, returned a 68 but also faded in his second round.
England's Brian Davis (69) and Scot Russell Knox (65) also missed out after poor second rounds.
