European skipper Padraig Harrington has rested Shane Lowry for the opening foursomes, which begin at 1.05pm this afternoon, on the first of the three-day event.
World number one Jon Rahm and Sergio Garcia will face Justin Thomas and Jordan Spieth in the opening match.
Paul Casey and Viktor Hovland are to take on Dustin Johnson and Collin Morikawa.
Lee Westwood and Matt Fitzpatrick are up against Brooks Koepka and Daniel Berger.
