And then there were four.
It's been a week of sensational blows in the WGC Dell Match Play at Austin Country Club.
Sergio Garcia, for example, drilled his drive at the short par-4 13th hole to inside 5-feet on Thursday and then made a hole-in-one on Friday.
Meanwhile, Robert MacIntyre confirmed his progress from the group stage late on Friday with a 371-yard drive at the 18th hole that left him 3-feet from the hole and Tommy Fleetwood opened the bracket stages with yet another ace.
But the biggest blows of all have been delivered to the glass jaws of the favourites.
Only one of the top 16 seeds made it to the weekend and the highest ranked player in the final four is 30th seed Scottie Scheffler.
He's joined in the Sunday action by his semi-final opponent Matt Kuchar, who won this championship in 2013, plus the first semi-final pairing of Billy Horschel and Victor Perez.
Scheffler was sensational on Saturday, playing his 31 holes in 15-under-par.
Here's what the quartet had to say about their progress so far and the prospect of winning on Sunday.
On the thrill of beating European Ryder Cup star Ian Poulter in the round of 16:
"I've watched Ian way too many times on TV just beat the crap out of us in the Ryder Cup. I have memories of me and my dad sitting on the couch, watching this guy make putt after putt. So it was nice to get one on him, at least for me."
On draining a birdie putt to match Jon Rahm's chip-in late in the quarter-final:
"That was a big one. I was standing there greenside and that was his do or die moment for the round. I had a feeling he was going to hit a really good shot and it happened to go in. I knew I had to roll mine in to keep things in check."
On walking the course as a spectator in the past:
"I was here my buddies and my wife messing around, gambling a little bit and having some fun. It's nice to be in front of a home crowd, I've got some friends and family out here."
On the prospect of strong winds on Sunday:
"I would rate myself as a pretty good wind player. I think it's going to be a different direction tomorrow, something these guys may not have seen. I may have the upper hand with a little bit of experience of that."
On his Saturday dogfight:
"To beat Jordan this morning, I don't think I led until the 18th hole. And then Brian is just one of those cagey bulldogs, it was going to take a great performance by me and thankfully I had another strong afternoon."
On needing to work on his swing during the Saturday lunch break:
"I wasn't thrilled with how I was driving it. Thankfully (my coach Chris O'Connel) was able to say the right thing, get the driver clicking again and I felt awfully good this afternoon."
On finding form out of nowhere:
"Certainly golf's a funny game and there are times as a professional where you can feel so far away, you think, 'Golly, I don't have it.' You're racking your brain trying to find it, but then you plug in the right ingredient, the right key, and then all of a sudden it snaps back. It's a lot more fun this way, I assure you."
On how he feels heading into Sunday:
"I can't tell you how good I feel right now. I feel like I'm still floating. Listen, there's a high level of intensity to make a 10-footer on the last to win the match and I feel incredible."
On his Saturday performance:
"I played really well this morning and decent this afternoon. I made two bogeys with two bad 3-putts, which doesn't usually happen for me. Swing got a little loose toward the end there and struggled on a couple of shots that I shouldn't have an issue with. But I was able to grind it out."
On rebounding from missed opportunities against Tommy Fleetwood:
"I was ticked off to miss a 4-footer. I gave a hole away to Tommy with a three-putt and then I tied a hole with him after he hit his tee shot in the water. But I knew I still was only one down with five holes left to play."
On his Sunday strategy:
"Play my game. I've played match play enough. I've tried to play the opponent. I've tried different strategies and I've realized I just need to play the golf course. Play my game and see where it puts me.
"I know what tomorrow means. I was in the final round with (winner) Colin Morikawa at The Concession (four weeks ago). Nothing changes. I'm not going to stress about it any more, I'm not going to worry about it."
On his energy levels:
"Oh, yeah, if anyone knows me, my tank's not empty."
On getting this far on debut:
"Sometimes ignorance is a good thing in golf, not really knowing what's coming! Obviously very happy. I think this morning was probably the best golf that I've played all week. It was a long day, you're up early, a short break, you get a little bit sluggish and then you have to get back on the course."
On being inspired by compatriot Victor Dubuisson's appearance in the 2014 final:
"I remember it was crazy how he made it to the final and then obviously those two amazing shots against Jason Day. It gave us the belief in France that it was possible and obviously I'm very pleased to be where I am today."
On the perils of trying to improve:
"Golf can be a funny game. You always want to improve but sometimes you try to improve and actually get a little worse. I'm a big believer in trying to get better at what you're already good at.
"My trainer says: 'Sharpen your sword, don't try to change your sword.' I think that's what I've been very disciplined at. For the longest time I was (torn) trying to hit fades and draws. Then I really committed to hitting just mostly fades off the tee, especially with the driver, accept that some holes don't fit and just build on that."
