Gene Sarazen. Ben Hogan. Gary Player. Jack Nicklaus. Tiger Woods. Rory McIlroy. Mike Prieskorn.
What do they have in common? Each has won the Career Grand Slam — the greatest individual achievement in the sport of golf, capturing all four of their era’s major championships. The first six names did it on the PGA Tour, across Augusta National and Pebble Beach and St. Andrews, with the world watching. Mike Prieskorn did it on September 13, 2026, at Fieldstone Golf Course in Auburn Hills, Michigan, on a par-72 layout, with a gallery gathered on the patio behind the 18th green, watching a man stand over a bogey putt that would complete a journey decades in the making.
Not even Arnold Palmer completed the Career Grand Slam. Mike Prieskorn has.
The 2026 Tour Championship brought 31 players to Fieldstone for the Mulligan Tour’s season finale — the last major of the year, the event that has closed every MT season since 2005, and the one trophy that had eluded Prieskorn through multiple heartbreaking near-misses. He finished second at the Tour Championship in 2016, losing in a putting green playoff to Mike Nicholas. He finished second in 2017 to Joe Brandenburg. He finished second again in 2023 to Chuck Withey. He had been to the mountain and come home without the flag so many times that the question wasn’t whether Prieskorn was good enough to win this tournament — it was whether the tournament would ever let him. On Sunday, it finally did.
The day began as a showcase from Tim Markel. Major Markel — the 2026 Match Play champion, the most decorated player in Western Division Championship history, a nine-time MT Major winner in his own right — came out and immediately announced his intentions. Six birdies on the front nine. Six. He made the turn at -5 in the kind of performance that has players checking the leaderboard and doing the math on whether anyone can catch him. For a stretch of time Saturday morning at Fieldstone, it looked like another chapter in the Major Markel story — another Tour Championship trophy to match the one he claimed at Eagle Eye GC in 2020, another signature performance in the season’s biggest event. The front nine gross of 38 told the whole story: the man was playing as well as anyone on the course.
In the last group of the day, Mike Prieskorn had other ideas.
Prieskorn made three birdies on the front nine and turned at -3 — two strokes behind Markel, but close enough to keep the pressure on from the other end of the tee sheet. The back nine at Fieldstone is where rounds are made and broken, and it made and broke both players on Saturday afternoon. Markel, who had built something that looked unassailable, ran into the reality that Fieldstone gives and Fieldstone takes. Three more birdies on the back — an extraordinary day by any measure, nine birdies total — were offset by three bogeys and a devastating double bogey on the tough par-4 15th that pushed him back to -1. Two holes remained. Markel responded the way champions respond — birdies on 16 and 18 to close at -3, a final gross 82 with 26 putts, the kind of day that wins most tournaments on most courses on most days. He planted his flag in the clubhouse and waited.
Prieskorn, watching Markel stumble at 15, saw the opening and ran through it. Three straight birdies to start the back nine took him to -6. Then came his own trouble — a double bogey on the long par-3 14th, the same hole that had taken down so many others on the day and a course-within-a-course at Fieldstone — before a birdie on 15 steadied the ship. He entered 18 holding a two-stroke lead over Markel, the Tour Championship trophy within reach after years of watching it belong to someone else.
The gallery on the patio was watching.
Fieldstone’s 18th is not a hole that offers comfort. It demands execution when execution is hardest, when nerves are at their peak and the enormity of the moment is pressing down on every swing. Prieskorn navigated it — not perfectly, not in the wire-to-wire dominant fashion the front nine might have suggested, but in the way that tournament golf actually works, in the grinding, anxious, one-foot-in-front-of-the-other fashion that separates the players who win championships from the ones who finish second. He reached the green. He stood over his bogey putt. He needed to make it. He made it.
Net 68, -4 for the day. The 2026 Tour Championship belonged to Mike Prieskorn.
The Career Grand Slam, on the Mulligan Tour, requires winning all four of the tour’s major championships: the Memorial Tournament, the Harbour Pointe Open, the Match Play Championship, and the Tour Championship. It is the highest individual achievement the Mulligan Tour offers, and it had never been accomplished until Saturday afternoon in Auburn Hills. Prieskorn joins the most exclusive list in the sport — not just the most exclusive list on the Mulligan Tour, but the most exclusive list in golf, period. The names above him on that list are the names that define the sport across generations. He belongs in that company now, on his own terms, on his own tour, with his own version of one of the game’s most storied achievements.
Tim Markel finished second at net 69 (-3), claiming $38 and delivering one of the finest individual Tour Championship performances in memory — nine birdies, 26 putts, a round that would have been the story of almost any other day. Greg Fobare finished third at net 73 (+1) for $28, continuing a season that will be remembered for years: five wins, three consecutive putt-off victories, and a money title that made him the undisputed face of the 2026 Mulligan Tour. Greg Kline took fourth at net 74 (+2) for $20 — the all-time wins leader and $3,000 career earnings milestone holder adding another paid finish to a résumé that already stands alone in tour history. A four-way tie for fifth at net 75 (+3) split $9.50 apiece among Vinnie Calles, Noah Kline, Jeff Klipa, and Corey McCue — the rookie Calles earning a Tour Championship check in his first season, a fitting exclamation point on the tour’s most remarkable class of newcomers in memory.
And that brings us to the 2026 Mulligan Tour Money Title. Greg Fobare — who arrived last year as a newcomer, who spent 2026 winning five tournaments and three putting green showdowns, who became the most talked-about player in Metro Detroit amateur golf between April and September — closed the year as the 2026 Money Titleist. Not even Fobare’s spectacular season could reach the Tour Championship trophy, but the money title is a full season’s worth of achievement, and nobody on the 2026 Mulligan Tour earned it more than he did. Fobare walks away from 2026 with five wins, a money crown, and a legacy that the tour will be measuring against for years to come. Chuck Withey, the defending money title holder, finishes the year with a strong second-place campaign — the two-time Tour Champion and money title defender going down swinging in the sport’s longest season.
The 2026 Mulligan Tour season is complete. It was a season of records and rookies, of Major milestones and memorable putts, of rain delays and rainouts, of albatrosses and hole-in-ones, of a bracket that upended every prediction and a money race that went to a relative rookie. It was the season Greg Fobare became Fobare. The season the rookies took over. The season Major Markel put his name in the history books. And most of all, it was the season Mike Prieskorn stood on the 18th green at Fieldstone, made the putt, and completed something no Mulligan Tour player had ever done before.
The Career Grand Slam. His alone.
See you in 2027.
