On a day in which it seemed nobody wanted to win a golf tournament, most folks thought a big name wound sneak in and swipe one at the very end.

Sergio Garcia? No, don't finish bogey-bogey.

Jordan Spieth? Negative.

Dustin Johnson then ... surely? Nope.

What about James Hahn?

Wait, who?

You know, the dude who heretofore is better known for dancing at the Phoenix Open than for anything he's ever done on an actual golf course?

Sure, him, the 297th-ranked golfer in the world, took down Paul Casey and Dustin Johnson after three playoff holes at Riviera Country Club on Sunday.

"I never would have though I would have won this golf tournament," said Hahn to CBS' Peter Kostis after his win. There are so many great players here -- Dustin, Sergio, Jordan -- just to be here competing with these guys is an honor."

It wasn't that long ago that Hahn was selling shoes at Nordstrom's and wondering if he'd have enough money to eat with. He also hones his swing by watching YouTube.

Now, after shooting 69-69 on the weekend at Riviera, he's headed to the Masters and has plenty of disposable income after pocketing over $1 million from winning at Riviera.

The ending was a masterpiece, too.

After all three golfers made par at the first playoff hole, Hahn and Johnson both made ludicrous birdies at the ridiculous par-4 10th with flop shots from behind the green out of the rough.

"I figured I had to go for it," said Hahn about his flop and subsequent 10-foot putt to get to the third playoff hole.

Other golfers who played the tournament were in disbelief.

It was on that third hole that Hahn holed a sizable birdie putt to take down Johnson for his first ever win.

I have a feeling it won't be his last.

Our grades for the 2015 Northern Trust Open:

Dustin Johnson: A

Johnson really couldn't have played the playoff any better than he did. He was looking to extend his tour-leading streak of consecutive seasons with a win to eight. He'll have several more months to get that done.

Finish: T2

Jordan Spieth: A

Spieth's final hole was pretty fascinating. At the time he was 6 under which, as it turns out, would have gotten him into a playoff.

At the time, though, he was down one to Johnson and Garcia so he went for broke and a chip-in hole out. It nearly happened, but he ran it six feet past and couldn't make the putt coming back for par.

Finish: T4

Bubba Watson: B+

It kept feeling like Watson was going to do something like he did last year when he shot 66-66 on the weekend to win, but he never could grab any momentum on Saturday and Sunday and a double bogey on No. 10 on Sunday was his ultimate undoing.

Finish: T14

Sergio Garcia: A-

Garcia needed nine shots on the last two holes to win, 10 to make a playoff. He took 11.

That's all you need to know, really.

Finish: T4

• The best 10 minutes of the entire week was the crazy birdie-birdie-birdie barrage at No. 16 on Saturday by Ryan Moore, Retief Goosen and Graham DeLaet. Moore hit the flagstick and putted from off the green, DeLaet hit a long putt and Goosen chipped in. It was thrilling at the time.

• Speaking of DeLaet, his beard is underrated, right? James Harden-like.

• Sergio art.

• What do the trio of Dustin Johnson, Jim Furyk and James Hahn talk about on Sunday? I want a transcript ASAP.

• Retief Goosen's swing. All the thumbs up emojis.

• One of my favorite things about TV broadcasts is the disbelief elicited by announcers everytime Dustin Johnson hits a bomb off the tee. Reminder: He hits a bomb off every tee.
