A hole-in-one is the luckiest shot in golf.
And because they're so good at what they do, it's no surprise that PGA Tour players seem to be luckier than the rest of us when it comes to jarring a tee shot in a single stroke.
Three golfers -- Matt Kuchar, Angel Cabrera and Grayson Murray -- all had two aces this season. Is that crazy, or what?
Here's a look at all 31 of the PGA Tour's aces in the 2016-17 season, accompanied by video where available.
If you have yet to record an ace, these will either infuriate or inspire you. We hope it's the latter.
1. Jon Rahm, No. 11 at Silverado Resort and Spa North in the first round of the Safeway Open
This was the first ace of the season. Unfortunately, no cameras were there to capture the moment. Rahm began the round on the 10th hole, so the "1" actually came on just his second hole of the season... and was seemingly a precursor for good fortune to come, as Rahm has compiled nine top-10 finishes through the Dell Technologies Championship, including a win, two runner-up finishes and two third-place showings.
2. Ken Duke, No. 11 at Silverado Resort and Spa North in the final round of the Safeway Open
The ace was a bright spot in an otherwise tough year on the course for Duke, who missed the cut in half of his 26 starts and had a best finish of T23 at Pebble Beach.
3. Kevin Na, No. 8 at TPC Kuala Lumpur in the third round of the CIMB Classic
With a 7-iron from 177 yards, Na hit the perfect shot. Three bounces and into the cup.
4. Steve Alker, No. 10 at Country Club of Jackson in the final round of the Sanderson Farms Championship
For Alker, from New Zealand, this was on his first hole of the day. And from 212 yards out, he jarred it. You can't get off to a better start than that.
5. Matt Kuchar, No. 17 at Sheshan International GC in the third round of the WGC-HSBC Champions
Kuuuuch! From 193 yards out... and it wouldn't be his only ace this season.
6. Greg Chalmers, No. 5 at TPC Summerlin in the second round of the Shriners Hospitals for Children Open
There's no available video of the shot, but Chalmers would miss the cut at the event with rounds of 71-71.
7. Aaron Wise, , No. 4 at El Camaleon GC in the first round of the OHL Classic
There's no video of the ace, but Wise's "1" was only half of an amazing two-hole stretch. He would eagle the very next hole, a par 5. Imagine that -- 4 under in two holes? Yeah, that works.
8. Marc Leishman, No. 8 at El Camaleon GC in the second round of the OHL Classic
There's no video of the ace, but Leishman would shoot a 65 in the round.
9. Chez Reavie, No. 17 at Waialae CC in the final round of the Sony Open
This was a 6-iron from 197 yards out. Incredibly, Reavie finished with a 60, one stroke shy of a 59... a score that eventual winner Justin Thomas actually shot that week. The ace put Reavie at 6 under through his first eight holes.
10. Angel Cabrera, No. 17 at the Nicklaus Tournament Course in the first round of the CareerBuilder Challenge
There's no video of the shot, but it's surely a highlight from a stellar career that the two-time major winner will always remember.
11. Scott Stallings, No. 15 at PGA National in the first round of the Honda Classic
Any ace is special, but it's extra special on a hole like the 15th at PGA National, the start of an agonizing three-hole stretch known as "The Bear Trap."
12. Jhonattan Vegas, No. 15 at PGA National in the final round of the Honda Classic
Three days after Stallings, on the same hole, Vegas knocked in a 6-iron from 179 yards out. Fantastic celebration.
13. Justin Thomas, No. 13 at Club de Golf Chapultepec in the third round of the WGC-Mexico Championship
Warms the heart to see Thomas make an ace in what otherwise would have been an abysmal year. Just kidding. Is this guy serious? What didn't he do in 2016-17? A 59. An ace. A bunch of PGA Tour wins. A major. Incredible stuff. By the way, that ace was a 6-iron from 232 yards. A 6-iron!
14. Hideto Tanihara, No. 7 at Austin CC in the WGC-Dell Technologies Match Play
Strategy is everything in match play. So, dialing up an ace against your opponent is actually the perfect strategy. That's exactly what Tanihara did in his consolation match against Bill Haas here from 201 yards with an 8 iron.
15. Angel Cabrera, No. 9 at Golf Club of Houston in the final round of the Shell Houston Open
Even through heavy rain, the 220-yard hole was no problem for Cabrera on his way to his second ace of the season. It was also his final hole of the day, so dinner tasted extra good that night.
16. Matt Kuchar, No. 16 at Augusta National Golf Club in the final round of the Masters
It seems fitting that the 16th hole-in-one made this season came on the 16th hole at the Masters. He did it just the way you're supposed to on that hole with the Sunday hole location -- by utilizing the backstop. And as far as celebrations go, there are few in golf more fun than Kuchar.
17. Peter Malnati, No. 17 at Harbour Town GL in the final round of the RBC Heritage
From 174 yards out, Malnati hit the perfect shot. It doesn't get any more center cut than that.
18. Sergio Garcia, No. 17 at TPC Sawgrass in the first round of the Players Championship
What's better than making a hole-in-one? Well, how about making a hole-on-one on one of the most famous holes in all of golf? That's what Garcia did in May. Quite the encore to his Masters victory a month earlier.
19. Brian Stuard, No. 16 at Colonial CC in the final round of the DEAN & DELUCA Invitational
Check out the unorthodox set up. It works for Stuard, clearly, as he knocks this one down from 192 yards out. Also, I'm a big fan of the one-bounce and in type aces.
20. Harold Varner III, No. 8 at Muirfield Village in the final round of the Memorial Tournament
While there was no video of the ace, Varner was happy to at least have a picture of the scorecard, displaying his first hole-in-one ever.
21. Grayson Murray, No. 8 at TPC River Highlands in the final round of the Travelers Championship
This was the first of two aces for the PGA Tour rookie this season.
22. John Merrick, No. 8 at RTJ Trail in the final round of the Barbasol Championship
Amazingly, that was one of two hole-outs for Merrick in the round.
23. Hudson Swafford, No. 15 at Firestone CC in the second round of the WGC-Bridgestone Invitational
With a 6-iron from 214 yards out, Swafford just threw an absolute dart. Gorgeous shot.
24. Joost Luiten, No. 4 at Quail Hollow in the first round of the PGA Championship
The fourth at Quail Hollow played as one of the most difficult par-3 holes you'll ever see. There was a lot of griping going on amongst players. Luiten, however, found an easy solution -- simply knock it in the hole from the tee.
25. Ben Crane, No. 16 at Sedgefield CC in the final round of the Wyndham Championship
As a prize for holing this tee shot from 175 yards, Crane received 1 million hotel rewards points from Wyndham. And, understandably, the celebration was A+.
26. Martin Flores, No. 16 at Sedgefield CC in the final round of the Wyndham Championship
This might be the most special ace of the season. Flores needed to make something happen late in his final round to secure his status on Tour for the 2017-18 season. This shot was just what the doctor ordered.
27. Roberto Castro, No. 3 at Sedgefield CC in the final round of the Wyndham Championship
Imagine that. Three aces in one day at this course!
28. Kevin Tway, No. 11 at TPC Boston in the first round of the Dell Technologies Championship
From 195 yards out with a 5-iron, Tway didn't need a putter on this hole.
29. Lucas Glover, No. 16 at TPC Boston in the second round of the Dell Technologies Championship
From 187 yards out on the 16th, Glover made the first of two aces that were 45 seconds a part.
30. Grayson Murray, No. 8 at TPC Boston in the second round of the Dell Technologies Championship
Just seconds after Glover's ace above -- literally -- Murray did this back at the eighth hole for his second hole-in-one of the season. Also of note here, Murray was playing alongside Kevin Tway, who aced the same hole a day earlier.
31. Jason Day, No. 17 at Conway Farms in the second round of the BMW Championship
What started as a rough week for Day, announcing that he split with longtime caddie Colin Swatton -- but would keep him on as swing coach -- seemed to be getting more and more memorable. First, he opened the tournament with a 7-under 64 for the early lead. Then, in round 2, from 188 yards out, he holed his tee shot on the par-3 17th for his second career PGA Tour ace.
