England's Brian Davis booked his place in the Open at Royal St George's after winning the US qualifying tournament at Gleneagles Country Club, Texas.
Davis shot a 64 to secure one of eight available positions from the event, which was reduced from 36 holes to 18 because of heavy rain and lightning.
Others to qualify for the major, which takes place in July, include Americans Chad Campbell and Davis Love III.
Spain's Sergio Garcia withdrew with an infected finger.
He pulled out after four holes, complaining that it was proving too difficult to hold the club.
Garcia has played in the last 13 Opens, finishing second in 2007, but he is not guaranteed a place in this year's field after his ranking fell to 73.
But the 31-year-old, who has struggled for form over the past few years, expects to be back in action later this week and could enter other qualifying events yet to be played.
The others to qualify were Australia's Nathan Green and Americans Spencer Levin, Chris Tidland, Bob Estes and Jerry Kelly, who won a six-way play-off for the final place.
