Makes his Open Championship debut as the record-breaking winner of January’s Latin America Amateur Championship – and it comes on the same Royal Liverpool course where compatriot Roberto de Vicenzo became Argentina’s first and so far only holder of the Claret Jug in 1967.
Joint runner-up in the same event last year, one stroke behind Cayman Islander Aaron Jarvis, he went clear of the field at the Grand Reserve club in Puerto Rico with a nine-under-par third round 63 which equalled the tournament best and, by adding a 67, won by four with a 23-under-par aggregate which broke the record by no fewer than eight strokes.
The victory came on the eve of his 23rd birthday and also earned him places in April’s Masters and the US Open.
“I’m still very shocked – I think my life has changed,” he said on collecting the trophy. "Going back to where Roberto won is very special. I went there in 2016 and they took me to the room where they have portraits and everything about where he won. I felt very proud.”
