The first round of the 108th PGA Championship at Aronimink finished on Thursday evening with a clubhouse leaderboard whose composition the betting market had not, on any of its lines, predicted. Aldrich Potgieter, the twenty-one-year-old South African who came into the week ranked first on the PGA Tour in driving distance and on a list of names whose major experience could be summarised on one line, posted a three-under sixty-seven in the second group off the tenth tee and watched the rest of the field, for the next nine hours, fail to better him. He shared the clubhouse lead at the end of the day with Stephan Jaeger, Min Woo Lee, Ryo Hisatsune, Martin Kaymer, Justin Thomas and Alex Smalley, all of whom had to grind, in varying degrees, to match what Potgieter had walked off the eighteenth green with at lunchtime.
The mark in the record
The line that the broadcast picked up by Thursday afternoon, and the line that has now circled the press tent, is that Potgieter, at twenty-one, is the second-youngest player ever to shoot sixty-seven or better in the first round of a PGA Championship. The only younger name on the list is Sergio Garcia, who shot sixty-six in the first round of the 1999 PGA at Medinah at the age of nineteen. The Garcia round, in retrospect, was the prelude to the Sunday duel with Tiger Woods that produced the eyes-closed seven-iron from behind the tree on the sixteenth and the leap up the fairway that has shown up in every Garcia montage since. The historical comparison is, on the surface, generous to a player making his sixth career major start and his first at this event. It also captures something the round itself did not need to advertise. Potgieter has, on the Tour this season, looked like a player whose ceiling, in the right conditions, is the kind of ceiling that the Tour does not produce very often.
The right conditions, on Thursday at Aronimink, turned out to be the conditions the course produced. The greens were firm, the rough was up, and the field average drifted out towards two over par by the early afternoon. Rory McIlroy carded a seventy-four. Bryson DeChambeau carded a seventy-six. The world number one, Scottie Scheffler, was at three under through eleven and inside the top of the leaderboard for most of his middle nine before a short par putt slipped past on the fourteenth and the closing holes pulled him back towards level. The version of the round that most of the field produced was a round in which Aronimink, on the first day of a major it had been waiting fifteen years to host, refused to give up anything that had not been properly earned.
What the game brings
The number Potgieter brings to Aronimink that almost no other player in the field can match is the driving distance figure. He averages three hundred and twenty-six yards on the Tour this year. The number is not, on its own, a guarantee of anything in major-championship golf, and the recent history of the PGA Championship is full of long hitters who have been dismantled by courses on which iron play and the short game decide every round. The course at Aronimink, however, is a course on which the longer player has, for most of the week, been quietly given an advantage. Several of the par-fours have been set up at lengths that ask the player to choose between a long iron approach from a fairway lie and a short iron approach from a position the architect has designed to be difficult. The longer hitter, on the second, the seventh, the twelfth and the seventeenth, can play the hole the architect was probably hoping the longer hitter could play. Potgieter spent Thursday morning playing those four holes that way.
The rest of the round was about the putter. The six birdies in his card came from inside fifteen feet in five cases and from a thirty-footer in the sixth. The putter has been, by his own admission in earlier press weeks this year, the part of the game he has worked on hardest since the Korn Ferry Tour win that produced his card. Putting at a major, on greens the field has not yet learned the speed of, is the part of the round on which a debut player will typically lose two or three shots without realising it. He did not lose those shots. He gained, by the close of his round, more than three strokes on the field putting. The combination of the driver and the putter, on a course that has not been giving anything away, is the combination that has produced the round.
The pairing and the weekend
The afternoon pairings on Friday will put Potgieter in the company of players who are slightly less used to seeing his name at the top of a major leaderboard than the early Thursday field were. The course is forecast to dry out further over the weekend. The wind, which sat at single figures on Thursday, is expected to come up on Saturday afternoon. The version of the week in which Potgieter is still on the clubhouse lead by Friday evening is the version that the broadcast will have to start treating as serious. The version in which he is still in the final group on Sunday is the version the betting market is now, very quietly, being asked to consider.
The history of the PGA Championship has, over the last fifteen years, settled into a pattern in which a new name will appear on the Thursday leaderboard, hold the lead through the cut, and then fade through Sunday’s back nine as the more experienced players in the field gather. The pattern is not a rule. Collin Morikawa was on the Thursday leaderboard at Harding Park in 2020. Justin Thomas was on it at Quail Hollow in 2017. Both played the back nine on Sunday on the lead and both walked off the eighteenth green with the trophy. The Thursday name does, in the right week, become the Sunday name. The question Aronimink will spend the next three days answering is whether the right week, for Aldrich Potgieter, is this one.
What the round means for the week
The wider effect of the round, on the rest of the field, is the effect a low number on a hard golf course always has on the rest of the field. The number is now in the building. The afternoon wave, which had been treating the course as if it were not allowing anything better than two under, has been told by the morning wave that three under is available. The afternoon wave then went out and produced a small handful of three-under rounds of its own, and a much larger number of rounds in which the player went after a flag the course was not asking the player to go after and finished the day at three over. The shape of the leaderboard at the end of round one is the shape the course has wanted to produce all week. A small group of players are in red figures by single digits, a much larger group are in single-digit red and red-adjacent figures, and the rest of the field is fighting the kind of cut line that majors at courses with this kind of green complex tend to produce.
The third round of the week is the round on which Aronimink will produce its first real winner story. The first round produced the first real surprise. The South African with the longest driver in the field is, until further notice, the player the course has been most willing to let through.
