NEWTOWN SQUARE, Pa. The 2026 PGA Championship opened on Thursday under a cool sky and steady wind, the kind of conditions that make a golf course tell the truth. Aronimink Golf Club, playing at 70 par and 7,394 yards, exposed precision and punished impatience. By evening, seven players had found their way to 3-under par, 67, and by any reckoning this was not a leaderboard shaped by a single story. It was shaped by breadth.
Aldrich Potgieter, Stephan Jaeger, Min Woo Lee, Ryo Hisatsune, Martin Kaymer, Scottie Scheffler, and Alex Smalley each signed for 67. They arrived there from seven different places in their careers.
The moment the round turned
The par-5 ninth at Aronimink, all 609 yards of it, was the field's most generous hole, offering birdies to whoever could reach it. It played to 4.795 strokes on average, a shade over a fifth of a stroke under par and the easiest hole on the property. The day's eagles, though, came elsewhere: Jon Rahm holed out for a two at the par-4 second, and Dan Brown did the same at the par-4 eleventh, the only two players to eagle a par-4 all day. No single hole was the round's hinge. Each was a detail in a larger pattern.
What mattered on Thursday was that the course, at 72.261 strokes on average, was playing honest. The front nine averaged 35.807, little more than a half stroke over par. The back nine, playing to a sterner test at 36.454, remained fair. The back nine could not hold anyone down. In these conditions, a player who placed his tee shots and kept his iron play clean could shoot 67. Seven of them did.
The defending champion
Scottie Scheffler, the 2025 PGA Championship winner, opened as a co-leader. Seeking to defend his title, he joined this group through the simplest of routes: fairways, greens, no bogeys, 67. He is trying to become the third player in the last 25 years to successfully defend the PGA Championship, joining Tiger Woods and Brooks Koepka. He has co-led after 18 holes in a title defense before, and the two men who did the same in this event in recent memory both went on to win: Woods in 2000, Koepka in 2019. His opening 67 says he intends to make that history live.
He arrives with more than a lead, though. He arrives with a record. In his last twenty starts in major championships, dating to the start of 2021, Scheffler owns top-10 finishes in sixteen. In each of his last six major championship appearances, he has finished inside the top 10. The math is with him. The golf is with him. This week will ask only one question: can the mind follow.
The field that gathered
Twelve former major champions sit within two shots of the lead, the most for any round in the history of major championships. The previous mark was eleven, set at the 1999 Masters. The club includes Brooks Koepka, five-time major winner, opening at 1-under after a 69. It includes Jordan Spieth, who holds a 69 from 2019 and 2024 at this event, matching his best score here in 14 starts. It includes Xander Schauffele, the 2024 PGA Championship winner, at 2-under. It includes Jon Rahm, Patrick Reed, Shane Lowry, and Jason Day. The depth is not a quirk. It is the tournament speaking.
What the field as a whole says is that Aronimink is playing neither as a fortress nor as a parlor trick. Thirty-three players sit within two shots of the lead, a new record for any round at a major championship. This is a course that gives birdies to the precise and does not punish the merely mortal. It is open to everyone.
The players who moved
One shot back, at 2-under, eight players sit in a tie that speaks to the breadth again. Corey Conners leads the field in Strokes Gained: Approach the Green at 3.936, a mark that says his iron play is the round's finest. Dan Brown and Jon Rahm are the only two players to take eagles on par-4s, Brown at the eleventh, Rahm at the second, evidence of birdie-making machinery at work.
Patrick Reed, who sits in this tie, is the only player to have gone 18 holes without a bogey. His 68, bogey-free and cleanly struck, carries the weight of a major championship moment.
The players who slipped
The youngest player in the field is Aldrich Potgieter, 21 years and 8 months old, a man making his PGA Championship debut. He opened with a 67 and shared the lead, the second 18-hole lead or co-lead of his entire career, the first since he won the 2025 Rocket Classic, where he earned his maiden PGA TOUR title. His presence at the top of this leaderboard is not a fluke; his putting leads the field. But the week ahead will test something deeper. He will sit with six other players, all of them older, all of them with more experience at this moment. Youth has its advantages. So does having been here before.
Rory McIlroy, among the game's most accomplished players still without a PGA Championship title, opened with a 74. The wind was against him; he hit five of fourteen fairways and bogeyed his final four holes, each a retreat into frustration. McIlroy's opening 74 is not a death sentence at a course this generous. But it is a reminder that even the best can be caught off the tee.
Where the course pushed back
The par-3 eighth at Aronimink measures 245 yards and played as the day's toughest hole, averaging 3.506 strokes. It is a demanding iron shot into a green that offers no refuge, and it took a half stroke from the field. Nowhere was the tariff more literal than at the first tee, where Garrick Higgo was assessed a two-stroke penalty for arriving late for his 7:18 a.m. time and still salvaged a 1-under 69. On a day when the course gave so much away, the reminders that it could still take were worth marking.
What tomorrow demands
Friday at the PGA Championship is about separation or its failure. With thirty-three players within two shots and a course this open, the cut at 36 holes will be generous, and the leaderboard will be crowded. The players at the top cannot rest on a 67. They must show that Thursday was not the wind talking. At the same time, the field that sits two or more back must shoot low numbers simply to stay in the conversation. In a major championship as broad as this one, breadth will not last past Friday.
The forecast calls for more cool air and a steady wind from the northwest. The course, still receptive, will keep offering birdies. Seven players found them on Thursday. Friday will ask the question all major championships ask: who among you can do it again.
