Back for the first time as a professional after appearing as European Amateur Champion both at Royal Liverpool in 2014 and St Andrews the following summer.
That was a truly memorable week, Chesters finishing a brilliant joint-12th and with a closing 69 overtaking fellow amateur Paul Dunne, who was tied for the lead with a round to go.
He did not take home the Silver Medal, however, as American Jordan Niebrugge shared sixth spot.
Later the same year at Royal Lytham & St Annes he won 3 ½ points out of four as Britain and Ireland lifted the Walker Cup, that half coming against Bryson DeChambeau in the first day singles before he beat Niebrugge 24 hours later.
Also that season was part of England’s side at the Eisenhower Trophy World Amateur Team Championship – DeChambeau was on the victorious side that time, although the leading individual was Jon Rahm.
Then turned professional, but while Rahm and DeChambeau reached first and fourth in the world his own ranking stood at 517th when he came joint third at November’s Joburg Open and took the last Open spot available in the Qualifying Series event because Shaun Norris – also seven under – was already exempt.
