A former winner of the British Boys' Amateur Championship, Otaegui is back in The Open four years after his debut at Royal Portrush.
He is now a four-time winner on the DP World Tour and was part of the Europe side at the Junior Ryder Cup in Kentucky. Just before his 18th birthday, he represented Spain in the 2010 Eisenhower Trophy World Team Championship.
Turned professional the following season and with three runner-up finishes on the Challenge Tour in 2013, earned promotion to the main circuit.
Twice failed to keep his card, but was joint winner of the 2015 qualifying school and in 2017 won his first crown at the Saltire Energy Paul Lawrie Match Play event in Germany. Home player Marcel Siem led the final by three at the turn, but Otaegui took six of the next eight holes.
His second win came last season at the Belgian Knock-out, which after 36 holes of stroke play became another match play event.
Further victories have come in the 2020 Scottish Championship – he beat Matt Wallace by four at Fairmont St Andrews – and in October 2022, he added the Estrella Damm Andalucia Masters at Valderrama by a massive six-stroke margin over Joakim Lagergren.
