Woods and McIlroy are Nos. 1 and 2 in FedEx Cup points, which the PGA Tour uses to decide Thursday and Friday groupings for the first two days of all four playoff events. With No. 3 Jason Dufner the only player in the field at this week's Wyndham Championship that could catch or pass McIlroy or Woods, the top two are assured playing together.
The reigning PGA champion and the world No. 3 have been grouped together before, playing for the first two days Abu Dhabi HSBC Championship in January.
