Ryder Cup team captains Steve Stricker and Padraig Harrington have confirmed their selections for the Friday four-ball session at Whistling Straits.
The United States took a 3-1 lead after the morning foursomes session in the 43rd edition of the tournament, with the hosts looking to wrestle the trophy back from Europe in Wisconsin.
Jon Rahm and Sergio Garcia got Europe off to a good start as they saw off Justin Thomas and Jordan Spieth 3 and 1, but Dustin Johnson and Collin Morikawa got the USA back on level pegging, with Brooks Koepka and Daniel Berger then edging out Lee Westwood and Matt Fitzpatrick.
Ryder Cup debutants Patrick Cantlay and Xander Schauffele did for Rory McIlroy and Ian Poulter, and Schauffele will be swiftly back out on the course as he pairs with Johnson for match one of the afternoon four-ball session.
The duo take on Paul Casey and Bernd Wiesberger, with match two seeing Bryson DeChambeau and Scottie Scheffler face Rahm and Tyrrell Hatton.
Match three pairs Tony Finau and Harris English together for the USA, with Rory McIlroy and Shane Lowry - who both represented Ireland at the Tokyo Olympics - teaming up.
The final four-ball match of the session will involve Thomas and Cantlay for the USA, with Tommy Fleetwood and Viktor Hovland their opponents.
