Match-play golf is just a different bird. How else do you explain that Tiger Woods made seven birdies by himself and lost his afternoon four-ball match?
So did Davis Love III make the right call to bench Tiger? And what do both squads need to do Saturday if they want to lead heading into the Sunday singles?
Our experts tackle those topics and more in our latest edition of Ryder Cup Four-Ball.
1. Thumbs up or thumbs down on Davis Love III's decision to bench Tiger Woods in the Saturday morning foursomes matches?
Michael Collins, ESPN.com senior golf analyst: Thumbs WAY up. Took a lot of the "captain" to make that move, but it was the right call. As well as Tiger played in the afternoon in four-ball, the format is nothing like foursomes.
Farrell Evans, ESPN.com senior golf writer: Thumbs up with some reservations. Tiger made seven birdies on his own ball in the afternoon four-ball. Why wouldn't Love let him ride that momentum into Saturday morning? But it's the captain's prerogative to pick his lineup.
Bob Harig, ESPN.com senior golf writer: Thumbs up -- if Love is doing it because he claims nobody will play five matches. It's probably a good idea to get some teams off the course. But Woods just came off making seven birdies Friday afternoon.
Gene Wojciechowski, ESPN.com senior national columnist: Thumbs up -- but reluctantly. It's more about the format than Tiger. Foursomes simply aren't a strength for him.
2. More impressive performance in Friday's four-balls match: Tiger Woods or Nicolas Colsaerts?
Michael Collins: Nicolas Colsaerts by far. We've seen Tiger have some great rounds in some big tournaments, but for a rookie in his first Ryder Cup to make eight birdies and an eagle to beat Tiger and Steve Stricker, that's impressive. And Colsaerts did it while playing with Lee Westwood, who didn't help other than with encouragement.
Farrell Evans: Nicolas Colsaerts is a rookie with little experience in the States. No question he was the best player Friday.
Bob Harig: Colsaerts, no doubt. In his first Ryder Cup appearance, he makes eight birdies and an eagle? And with virtually no help from Westwood? And beats Woods and Stricker, who were 9 under? Amazing.
Gene Wojciechowski: Even Tiger was amazed by how well Colsaerts played. What Colsaerts did in his first Ryder Cup appearance was jaw-dropping.
3. Who was Team USA's man of the match Friday?
Michael Collins: Keegan Bradley. He was the man who brought the crowds to a fever pitch and even had Mickelson screaming "WOW" after some of the things he did. He's 2-0 with Mickelson so far, and both matches were against Europe's biggest guns.
Farrell Evans: Keegan Bradley. He brought Mickelson back to life in these matches. That's priceless.
Bob Harig: Keegan Bradley, without question. In his first Ryder Cup appearance, he was terrific, partnering with Mickelson to win two points. Bradley said he wanted to play 36 more holes, and it would be tough to doubt him.
Gene Wojciechowski: Bradley Keegan. Next question.
4. What do the U.S. and Europe teams each have to do if they want to be leading after Saturday's play?
Michael Collins: Europe has to dominate foursomes and get at least a 3-1 outcome, then play much better in four-ball. The U.S. needs to feed off its momentum from the afternoon session Friday and get another 2-2 in foursomes. That momentum will carry the U.S. through to a lead after the afternoon session as well.
Farrell Evans: The U.S. just has to continue playing solid golf. The Europeans need to try to hide their weak links such as Martin Kaymer, Paul Lawrie and Westwood. The Americans proved Friday that they have 12 strong players.
Bob Harig: The U.S. needs to win only half the available points Saturday to accomplish that goal, and it has a couple of hot teams in Mickelson-Bradley and Bubba Watson-Webb Simpson to help get that done. The Europeans have the much tougher task and probably need to lean on the heavyweights: Luke Donald, Sergio Garcia, Rory McIlroy, Graeme McDowell, Ian Poulter and Justin Rose. If Colsaerts can continue his excellent play, that would give Europe an added boost.
Gene Wojciechowski: For Team Europe, I recommend it kidnap the team of Bradley and Mickelson. For Team USA, just pretend Saturday is Friday again.
