McIlroy will start with a slight edge

RORY McIlroy is ranked second in the world, but will start this week’s PGA Championship in San Francisco as the man to beat.

The Northern Irishman is fancied to land his fifth Major title ahead of world number one Spaniard Jon Rahm and American super-hero Bryson DeChambeau. They are joint second in the odds on who will prevail at TPC Harding Park - the Californian course making its debut as one of the Major venues.
