Sebastian Munoz can multiply his career PGA Tour earnings by a factor of nearly 10 on Sunday with a win at the Greenbrier Classic. Munoz, who has earned just over $120,000 in his career, is looking to go wire-to-wire at the Greenbrier Classic for his first ever win on the PGA Tour.

Munoz actually doesn't even have a top 25 in 11 starts on this tour with his best finish (ever!) coming at the Texas Open earlier this year where he finished T27. He leads the Greenbrier by two over Robert Streb and three over Xander Schauffele and Jamie Lovemark after three rounds. Munoz, who is 14 under overall, shot a 68 on Saturday to back up his 61-67 start.

"I try to play boring golf," Munoz said. "I try to hit the fairway and hit the greens. Even though I try, I just seem to put myself into some trouble and then trying to make something happen and then kind of get on a good run, sometimes bad runs.

"I think I had a good round today by the way I just hit the ball from the tee again. A lot of missed fairways in the first nine. I think I was getting a little too quick, out of rhythm. And then we kind of managed to settle in with a couple clutch putts, save par, and good chips."

Munoz didn't make a bogey over the last 13 holes and is No. 1 in the field this week in strokes gained putting. So I know the question everyone is wondering is, who the heck is this guy?

Munoz played college golf at North Texas and won on the Tour last season. He had one of the lowest priority rankings coming into this PGA Tour season, though, as he missed 11 of his last 12 cuts (!) on the Tour last year. He narrowly finished inside the top 25 on that tour to squeeze into getting his PGA Tour card.

To be frank, him winning this week against the Phil Mickelsons and Patrick Reeds of the world would be a near miracle considering he was barely competing against Tour-level players 12 months ago. That doesn't mean he can't ride his heater all the way home, only that it doesn't seem likely.

"The support of the crowd is great," Munoz said. "I feel like they generally want me to win. Like I just feel the support, and that's also nice. That's just how it felt back home.

"I feel like I'm pretty calmed down out there. I don't know what you guys watch on the TV, but I feel like I'm pretty calmed down, steady, and ready to hit the next shot."

He's looked the part so far, but Munoz has a lot working against him. He'll have some salty veterans trying to chase him down, the burden of sleeping on a 54-hole lead and the fact that nobody has ever won this tournament after holding the 18-hole lead (which Munoz did). 

He seems pretty unbothered by it all, though.

"I am going to try to do the same thing." Munoz said of what his Sunday routine will be. "I've had my phone off since Thursday. We're going to keep it that way. Just watch the movie, relax in the morning, have some breakfast, and get ready. Watch some tennis."

Watch the movie, watch some tennis and play some golf. Seems like a fun Sunday ... with $1 million and a two-year exemption on the line. Will Munoz melt under the pressure, or will he stand strong in the heat of his first true test on this tour?

We have no idea what's going to happen, but Sunday is going to be dramatic either way.
