Martin Kaymer cool when it counted

We saw a tale of two Martin Kaymers at TPC Sawgrass during the final round of the Players Championship on Sunday: the first one before the rains came, and the second, much more exciting version, post-thunderstorm.

So what impressed the most about the 2010 PGA Championship winner's victory Sunday? And what happened to Jordan Spieth in the final round?

Our scribes dive into those topics and more in the latest edition of Four-Ball.

1. More impressive: Martin Kaymer's first 13½ holes or how he played 17 and 18?

Michael Collins, ESPN.com senior golf analyst: The composure he showed on the 17th and 18th holes when it was all on the line ... I don't know what beats that looking back at the first 16 holes.

Farrell Evans, ESPN.com senior golf writer: It has to be those last two holes, where Kaymer is clearly struggling with his nerves and his game. His save on the 17th was one of the more impressive pars in 2014 and in the tournament's illustrious history.

Bob Harig, ESPN.com senior golf writer: The way he played 17 and 18, and only because it took a lot of moxie to hole that par putt on the 17th, followed by a drive he's not comfortable hitting at the 18th and then rattling in the 4-footer to avoid a playoff.

Kevin Maguire, ESPN.com senior golf editor: The last two holes really put the stamp on the 2014 Players, most specifically that putt on No. 17. Kaymer had made several mental miscues in the last couple of holes, but draining that bomb for par on 17 will be replayed for years to come during Players Championship week.

2. What sidetracked Jordan Spieth most from winning at TPC Sawgrass?

Collins: I don't think there was any one thing. He seemed like he wasn't in a great place mentally all day, so when the first bogey of the week came and he didn't make the bounce back birdie, he seemed to be easily frustrated. Can't win like that.

Evans: Nothing against Patrick Reed, but Spieth is a legitimate top-five player. And perhaps the most remarkable aspect of Spieth's rise to prominence is that he's done it without superb statistics from tee to green. On Sunday, he couldn't make enough birdies to offset his five bogeys. When his ball striking improves, he is going to be very tough to beat.

Harig: His short game. As he said, it simply wasn't as magical as it had been the first three days, and he needed to convert more putts to have a chance of winning.

Maguire: His short game. Spieth was perfect the first three rounds, making every chip and putt that he need to go bogey-free. That magic disappeared during the final round, whether it was for birdies on par-5s like at No. 9 or to save par in several situations on Sunday.

3. Fact or fiction: Jordan Spieth will be on the 2014 U.S. Ryder Cup team.

Collins: Fact. It's all about the future, so even if he doesn't make it on points, captain Tom Watson should make him a pick. He's a great teammate and will only be an asset moving forward.

Evans: Fact. Outside of an injury, I think he has to be on that team. Last year's Presidents Cup was a good primer for what he will experience in Scotland in September.

Harig: Fact. He almost assuredly will make the team on his own, but even if he doesn't, Tom Watson would be wise to pick him. Having last year's Presidents Cup experience is as key as putting himself in contention as often as he has this year.

Maguire: Fact. He was fifth in the standings coming into Players Championship week, and even though there's a long way to go and three major championships remaining before Tom Watson fills out his team with three captain's picks, I can't imagine a scenario where the 20-year-old is sitting at home the last week of September. He's the future of American golf right now, and barring injury, he'll be at Gleneagles.

4. Thumbs up or thumbs down to 17-year-old Scottie Scheffler playing this week's HP Byron Nelson Championship?

Collins: Thumbs up. The way teenagers have been performing in PGA Tour events the last two years, would anyone be surprised if the kid gets a top 10? Take a page from the LPGA Tour and get the young talent out here now!

Evans: Thumbs up. All you need to know why this is a good idea for the tournament and the game is two words -- Jordan Spieth, who made the best of this opportunity when he was a 16-year-old in 2010.

Harig: Thumbs up. Why not? This is great experience for young players. And if you recall, Jordan Spieth got a similar opportunity in the same tournament when he was just 16.

Maguire: Thumbs up. Golf is the ultimate sport in telling you early if you're able to play with the big boys. Jordan Spieth could do it (finished T-16 at this event as a teenager), and we'll see if Scheffler is up to the task as well. If he can't, he goes back to playing against juniors. It's not like it's the NFL where there might be physical scars or damage from this experience. He'll only grow from it.
