The cheerleaders have arrived. Tony Finau, arms pumping and voice roaring, gees up the home fans as he springs onto the first tee.
"Let's go captain!" the punters chant when they spot Steve Stricker. Even his admission yesterday he is a Chicago Bears fan has not put off the Wisconsinites.
Jeers greet the Europeans - but they lap it up. Tommy Fleetwood, who like Finau is not playing in the foursomes, is buzzing. Like he's come out on stage ready to play a gig. Only his bass guitar is missing.
Vice-captain Graeme McDowell encourages the fans to go louder as each of three sides consecutively chant U, S and A.
More like pantomime than hostility at the moment.
