Jason Day

Seven wins in under a year, which included his first major at the 2015 PGA Championship, a second World Golf Championship and the 2016 Players Championship, propelled Jason Day to world No 1. 

At Whistling Straits former world junior champion Day became the first player to finish a major 20-under par as he beat Jordan Spieth by three strokes. 

A month earlier he had a putt to tie for The Open at St Andrews but left it inches short. 

The following season he came close to a successful defence of the PGA crown with a last-hole eagle but Jimmy Walker pipped him by a stroke. 

His two World Golf Championship titles have come in matchplay, Victor Dubuisson being beaten in sudden death in the 2014 final and then Rory McIlroy and Louis Oosthuizen being his last two victims in 2016. 

He was runner-up in both the Masters and US Open - only his third and fourth majors – in 2011 and two years later the Presidents Cup regular came second at the US Open again. 

He took individual and team honours in the 2013 World Cup at Royal Melbourne and recorded his 11th and 12th PGA Tour wins in 2018.
