Scottie Scheffler claims Open Championship with majestic four-shot win

• American world No 1 ends on 17 under at Royal Portrush

• Rory McIlroy finishes at 10 under after final round of 69

Never in doubt. Never remotely in doubt. It was Scottie Scheffler: why on earth would it be?

Anybody hoping for a keenly contested Open Sunday was to be sorely disappointed. Make that 10 times Scheffler has held a 54-hole lead and 10 times he has converted.
