Rory McIlroy and Jordan Spieth to play together at Sawgrass

The leading two players in the world will be joined by seventh-ranked Jason Day in a star-studded three-ball on Thursday and Friday - they tee-off at 1:39pm BST in the opening round and 6:49pm on Friday.
Spieth denied McIlroy the chance to complete a career grand slam when he stormed to victory in the Masters at Augusta National last month.
