Tyler Duncan played his best golf over the final nine holes of his long season, making four birdies on the back nine to close with a 66. That meant getting a PGA Tour card for the third straight season, twice through what now is called the Korn Ferry Tour Finals.

D.J. Trahan also delivered a clutch moment with an approach to 3 feet for birdie on the last hole to get one of the last cards.

The Korn Ferry Tour Championship, the final chance to earn a PGA Tour card for 25 players, was at times exciting, exhausting and exhilarating for those who made it. And it’s also just the start.

Getting a PGA Tour card is tough. Keeping it is no picnic.

The new PGA Tour season starts Sept. 12 at the Greenbrier, with six domestic events and one at the Mexican resort of Mayakoba, all of them offering full FedEx Cup points and an invitation to the Masters for the winner.

Optimism is never higher. The PGA Tour in September is right up there with Major League Baseball in March.

Now for the bad news: If the last three years are any indication, some 60 percent of the players who earned PGA Tour cards won’t be keeping them.

Of the 50 players who earned PGA Tour cards last year — either the regular season or the Finals series of what is now the Korn Ferry Tour — 31 failed to finish among the top 125 in the FedEx Cup to retain full status.

Thirty players failed to keep their cards in 2018, and 29 did not keep their cards in 2017.

As for that optimism? There’s no predicting who’s going to get hot in what week. One adage passed down from veterans over the years is that players typically make 80 percent of their money from 20 percent of their tournaments. Five players who earned cards from the Korn Ferry Tour — either the regular season or the Finals series — won on the PGA Tour the next year. That includes Max Homa at Quail Hollow and Adam Long at the Desert Classic, where he beat Phil Mickelson by one shot.

The previous year, seven players who had to earn Tour cards went on to win, four of them getting a Masters invitation. That group included Ted Potter Jr., who took down Dustin Johnson at Pebble Beach. And in 2016-17, the list of nine winners included Xander Schauffele and Bryson DeChambeau.

Calling on the Hall

Justin Rose doesn’t know the criteria to be considered or even voted for the World Golf Hall of Fame.

His objective is to take the guesswork out of the equation.

Strictly by his PGA Tour record, Rose has too many other players ahead of his 10 victories and one major championship. But he has 10 other victories on the other five major tours in golf, not to mention that Olympic gold medal from Rio in 2016. He also has a FedEx Cup title and has reached No. 1 in the world.

“I’m knocking on the door, but I feel like you want to bash the door down and make it an easy decision,” Rose said. “I don’t want to be on the fringe of it.”

Next in line is Tiger Woods, who turns 44 at the end of the year. Rose turns 40 next year, as does Adam Scott, who has more victories on the PGA Tour and worldwide; and Sergio Garcia. Jim Furyk also merits plenty of consideration with his 17 victories, a U.S. Open and uncanny consistency.

“Is it two majors and 20 PGA Tour events? I don’t know if there’s a criteria,” Rose said. “I’ve definitely had some cool moments in my career that definitely stand out. Hopefully, if it ever happened, they’d look favorably on that stuff. But I want to kick on. I want to prove more to myself. I want to be a multiple major champion.”

He mentioned players like Jordan Spieth, Brooks Koepka and Padraig Harrington, each of whom won three majors or more in a span of three seasons.

“If you catch fire and you catch a break here and there, you can pick up a couple of majors pretty quick,” he said. “So I’m looking for one of those spells and phases late in my career.”

Chip shots

Kevin Tway began the season by winning the Safeway Open in a three-way playoff. Three weeks later, Xander Schauffele made birdie on the first extra hole to beat Tony Finau in a playoff in Shanghai. Charles Howell III ended the fall portion of the season with a playoff victory at Sea Island over Patrick Rodgers.

That was on Nov. 18. And that was the last playoff of the PGA Tour season.

None of the 37 tournaments (stroke play) from Kapalua in January through East Lake in August had to go extra holes.

... For the fifth straight year, the PGA Tour had more than 100 players go over $1 million in earnings for the year. There were 114 millionaires in 2019, tying the record set the previous year.
