The United States launched their bid to reclaim the Ryder Cup from Europe as the action teed off at Whistling Straits on Friday.
Sergio Garcia, playing alongside Spanish compatriot Jon Rahm, had the honour of hitting the opening shot in the morning foursomes, with Jordan Spieth and Justin Thomas providing the opposition.
A raucous crowd created a tremendous atmosphere on the first tee in Wisconsin, with some boos for Europe, for whom Garcia drove into a bunker before Thomas responded by finding the fairway.
Europe, then led by Thomas Bjorn, won by seven points last time out at Le Golf National in 2018 and new captain Padraig Harrington has gone for experience to kick off his team's campaign after a year's delay amid the coronavirus pandemic.

Paul Casey, 44, joins Viktor Hovland against Dustin Johnson and Open champion Collin Morikawa in the next match out, followed by the 48-year-old Lee Westwood and Matthew Fitzpatrick against Brooks Koepka and Daniel Berger.
The final clash of the opening session pits Ian Poulter, 45, and Rory McIlroy against the rookie American duo of Patrick Cantlay and Xander Schauffele.
Europe have left Tommy Fleetwood, Tyrrell Hatton, Shane Lowry and Bernd Wiesberger on the sidelines for the opening matches, while Bryson DeChambeau, Harris English, Tony Finau and Scottie Scheffler miss out for the hosts.
The fourballs pairings will be confirmed later in the day.
