William Hill Rory McIlroy betting offer: get 150-1 on McIlroy to win

Rory McIlroy ended a ten-year Majors drought with an emotional Masters victory in April, and the Northern Irishman will hope to cap one of the most memorable seasons of his glittering career when he tees it in his homeland at the Open Championship this week.

McIlroy, an Open champion at Hoylake in 2014, shared second place in the Scottish Open last week, warmly up nicely for a tilt at a second Claret Jug.

After falling short at Royal Portrush in 2019, when his close friend Shane Lowry was crowned Champion Golfer of the Year, McIlroy will be determined to take his chance this time around.
