Here's Friday's lineup, with the fourth match the headliner, via the good folks at CBS Sports' Eye On Golf, who remind us of the rules:

The morning session will be of the fourball variety which means a team's score is the best score posted by one of the two golfers on a given hole. So if Keegan Bradley birdies the first hole and Phil Mickelson pars it then the US score for that hole is a birdie.

Action begins at 2:35 a.m. ET on Friday. Set your alarm. Set multiple alarms.

Match 1 - 2:35 a.m. ET

Team Europe: Justin Rose and Henrik Stenson
Team USA: Webb Simpson and Bubba Watson

Match 2 - 2:50 a.m. ET

Europe: Thomas Bjorn and Martin Kaymer
USA: Rickie Fowler and Jimmy Walker

Match 3 - 3:05 a.m. ET

Europe: Stephen Gallacher and Ian Poulter
USA: Patrick Reed and Jordan Spieth

Match 4 - 3:20 a.m. ET

USA: Keegan Bradley and Phil Mickelson

Sitting out for Europe: Jamie Donaldson, Victor Dubuisson, Graeme McDowell, and Lee Westwood.

Sitting out for the U.S.: Jim Furyk, Zach Johnson, Matt Kuchar, and Hunter Mahan. 

"I told (Spieth and Reed) today I'm going to throw you in the ocean without a life preserver," Watson added. 

That's the spirit, Captain.
