Shane Lowry and Rory McIlroy happy despite trailing runaway leader at the Masters

Wild winds, a shock withdrawal of the world number one and some equally surprising scores marked the opening round of the 2017 Masters as American Charley Hoffman carved out a big 18-hole lead to take into Friday's play, writes Simon Lewis.

Hoffman, 40, made light of the difficult weather conditions to post an opening 65, seven under par and four clear of second-placed Will McGirt.
