The pairings for the afternoon were announced with some foursomes still out on the course and the McIlroy-Poulter duo is arguably the pick of the bunch.
It will be the first time that world number one McIlroy is not joined on the course by usual teammate Graeme McDowell, who has been left out.

6.05pm: D Johnson/Kuchar vs. Colsaerts/Lawrie
6.20pm: Watson/Simpson vs. Rose/Molinari
6.35pm: Woods/Stricker vs. Garcia/Donald
6.50pm: Dufner/Johnson vs. McIlroy/Poulter
