De Jager became the South African amateur champion in 2007 and has since had five victories on his home Sunshine Tour, most notably the 2019 PGA Championship.
He now appears in his first Open Championship after taking the second of three places on offer in the 36-hole Final Qualifying at West Lancashire on June 29, when he recovered from a quadruple bogey nine on the 11th hole of his second round with three birdies in the last five.
De Jager has had some near-misses in European Tour events. Two years ago he shared second place at the Kenya Open, finishing only one stroke behind Italian Guido Migliozzi, and back in 2013 he was third at the co-sanctioned Tshwane Open, three shots adrift of fellow countryman Dawie van der Walt.
His debut on the circuit came way back in 2007 at the age of 20 and he made his first attempt to qualify for The Open in 2013.
“This is amazing - it’s going to be my first major and I don’t think there could be a better one to start off with,” he said. “I know Ben Curtis won at Royal St George’s in his first time playing The Open, so I think that is a good omen.”
