AUGUSTA, Georgia (Reuters) - Scottie Scheffler says golf is just something he does but will not define him even though the world number one is doing it better than anyone else.

Unassuming and thoughtful, Scheffler is more than the sum of pars, birdies and bogeys on his scorecard but coming into this week's Masters he has been the definition of golfing excellence.

With back-to-back wins at the Arnold Palmer and Players Championship and a runner-up finish at the Houston Open, Scheffler is hot favourite to slip into the Green Jacket on Sunday, which would add to his reputation as a golfing machine.
