Andrade had rounds of 68-69 at Ansley Golf Club in Roswell, Ga. He finished one stroke behind Luke List, an 18-year-old high school senior who will play for Vanderbilt next year.
The U.S. Open is next week at Olympia Fields Country Club outside Chicago.
The biggest batch of qualifiers won't be decided until Wednesday because of rain. Most of the PGA Tour players, including Hal Sutton and John Daly, are in Rockville, Md. They were unable to finish, and scores were not available until the entire field was in.
Former U.S. Amateur champion Matt Kuchar never had a chance at Ansley's Settindown Creek course, opening with an 80.
In other qualifiers:
-- Fredrik Jacobson of Sweden, a two-time winner on the European tour this year, qualified for his first U.S. Open at Century Country Club in Purchase, N.Y. Jacobson was the medalist at 4-under 138 and took one of the four spots available. The others went to Geoff Sisk, John Maginnes and Courtney Brisson.
-- Sean Murphy, who has spent most of his career on the Nationwide Tour, led three players who qualified at Chevy Chase Country Club in Maryland. The others were former PGA Tour winner Dicky Pride and Chris Anderson.
-- Grant Waite was among five players who qualified at Lake Nona in Orlando, Fla. The medalists were Maarten Lafeber of Holland and Matt Seppanen, both at 5-under 139.
Robert Floyd, son of the former U.S. Open champion Raymond Floyd, was among those who failed to qualify at Lake Nona. His brother, Raymond Floyd Jr., failed to make it out of the qualifier in New York.
Craig Perks, who won The Players Championship a year ago with an eagle-birdie-par finish, also failed to earn a spot out of Lake Nona.
