At 6ft 9ins Thomson became the tallest player in European Tour history when he came through the Qualifying School in 2017 and he was very nearly a winner the following season.
At the Made in Denmark tournament he tied with Matt Wallace, Lee Westwood and Steven Brown, but it was Wallace who won in sudden death.
Thomson now makes his major championship debut after finishing second to New Zealander Daniel Hillier in the 36-hole Final Qualifying at Hollinwell, where he is the attached professional.
Known as “Jigger” – it was coined because he often danced in his nappies as a toddler – he returned rounds of 69 and 65 to be one behind Hillier on 10 under par.
Thomson first picked up a club at the age of five at Rotherham Golf Club, where he practised alongside a promising group of youngsters including future Masters winner Danny Willett.
He then battled leukaemia for five years, but was still able to work on his golf game after having to give up impact sports.
In January last year he equalled a long-standing world record for the most consecutive birdies as he recorded a phenomenal nine in a row on the Portugal Pro Tour.
