The Latest on the Ryder Cup (all times local):
The Ryder Cup is known for its euphoric atmosphere, and Hazeltine is holding up its end of the bargain.
The first tee has taken on the energy of a rock concert, with the DJ blasting Prince's "Let's Go Crazy" before the sun had risen to fire up the home crowd. Thousands packed into the grandstand, with the American chants of "USA! USA!" drowning out the familiar European "Ole! Ole ole ole!" song.
A brief video tribute to the late Arnold Palmer was played before the first group started as the partisan American crowd chanted "I believe that we will win!"
The colorful gallery included a group wearing red, white and blue Team USA hockey jerseys with Viking horns in homage to the local NFL team. Two spectators wore large, pink cat masks in the front row.
The 41st Ryder Cup is off to a rollicking start at Hazeltine.
With a rowdy gallery serving as the backdrop, Jordan Spieth and Patrick Reed led things off for the Americans against Henrik Stenson and Justin Rose for Europe, which is looking for its fourth straight Ryder Cup victory.
Reed hit the first tee shot for the United States, which has lost eight of the last 10 in the biannual showdown. The first matchup was all square after the first hole.
The other matchups in the morning foursomes were Phil Mickelson and Rickie Fowler against Europeans Rory McIlroy and Andy Sullivan, Jimmy Walker and Zach Johnson against Sergio Garcia and Martin Kaymer and Dustin Johnson and Matt Kuchar against Lee Westwood and Thomas Pieters.
