The 51st Walker Cup got underway at Lahinch Golf Club in County Clare, Ireland, on Saturday, and it didn’t take long for a rare hiccup to happen. It involved two top amateurs, a rare gaffe, and a rules official who stepped in to offer a solution.

During the morning foursomes, Great Britain & Ireland’s Niall Sheils Donegan, a former Northwestern Wildcat now playing for the University of North Carolina, found himself at the center of a rules fiasco. Donegan and Josh Hill went head to head against Josiah Gilbert and Ryder Cowan and dominated from the start. They went 4-up through the eighth hole. But on the ninth, the 21-year-old golfer made a rookie mistake.

Gilbert and Cowan made par on the hole, while Donegan had a six-footer for birdie. But he struck it too hard, and the ball rolled past the hole by a foot. Perhaps annoyed at the miss, Donegan quickly scooped up the ball with his putter, taking a big, long step, as you can see here. He thought the putt was conceded. Or, at least it’ll be. He thought that would halve the hole and move to 10th. The problem?

The putt was never conceded. Before Cowan or his teammate, Gilbert, could nod in agreement or give a thumbs-up, Donegan raked the ball in. Everyone was confused, and Hill, Donegan’s partner, immediately understood his teammate made a rookie match-play gaffe.

Ryder Cowan of Team USA stepped forward and told Donegan that the putt wasn’t conceded. After a brief discussion, the officials sided with the Americans, ruling that the putt hadn’t been conceded. So the hole went to the U.S., trimming Donegan and Hill’s lead from 4-up to 3-up heading into the back nine.

Had Donegan just left it alone, the hole would have almost certainly been halved, since both sides had made four. In the wake of the little controversy, Cowan caught a lot of flak with some questioning the necessity of him bringing in an official.

“Classless. Cowan should hang his head in shame,” one fan wrote. “Oh man, why didn’t he give it to him?” another fan commented. Some argued that, as a gesture of sportsmanship, he should’ve let it go, but before you criticize the 21-year-old, hear what the reports from the ground say.

Donegan was angry at himself, and Cowan was embarrassed to have played the villain

Niall Sheils Donegan himself refused to blame his opponent. Rather, he was frustrated with himself for making such a silly gaffe in a tournament like the Walker Cup.

“It was completely on me,” Donegan said via Golf Channel’s Brentley Romine. “I hit the 6-footer and missed it like an idiot. I had a foot back, and I just dragged it away like I’m in a Sunday bounce game, but those aren’t the rules of golf.”

In fact, reports from Lahinch suggest that Ryder Cowan was also a bit embarrassed before flagging the mistake to Donegan.

Noted journalist Geoff Shackelford wrote on Quadrilateral: “The moment highlighted Cowan’s good-hearted nature. Borderline apologetic, he approached Sheils Donegan and could be seen saying he hadn’t had a chance to give the putt. Cowan’s body language suggested that he was almost embarrassed to have to be a stickler, but the admirable modesty was unnecessary.”

Moreover, the match-play rules are forthright in this matter:

• Under Rule 3.2b, the concession in match play has to be communicated clearly, either verbally or through an unmistakable gesture like a wave or thumbs up.
• Silence or an opponent simply not objecting doesn’t count. Until this happens, the ball is still in play, and a player isn’t allowed to lift it.
• The penalty in match play isn’t just a stroke; it’s a loss of the hole outright.

So Cowan didn’t have much of a choice, and he addressed the matter politely, which helped reach an amicable solution. Cowan is a senior at Oklahoma Sooners and was the low amateur at the 2026 U.S. Open along with Jackson Koivun.

Cowan-Donegan incident is different from Pettersen-Lee controversy at Solheim Cup

Back in 2015, Team USA’s Alison Lee made a similar mistake as Donegan. But in her case, it boiled over into a bigger controversy. Lee’s birdie putt stopped two feet short, and she thought Europe had conceded the putt when Charley Hull was seen walking off the green.

However, Hull later claimed she only went to consult Pettersen on whether they should concede or not. Pettersen claimed they never conceded, and eventually the hole went to Team Europe as they took a 10-6 lead heading to Sunday Singles.

Although Team USA won the tournament, everyone from Juli Inkster to Laura Davies called Pettersen’s actions shameful and disrespectful. She later apologized to Team USA and said it offered a valuable lesson. In Cowan and Donegan’s case, the non-conceded putt wasn’t as consequential.

Cowan and Gilbert failed to make a late charge. Instead, on the 12th, they gave one more point to Donegan and Hill. The match ended on the 15th hole when Hill saved par to hand GB&I a 4-and-3 victory.

Overall, Great Britain and Ireland lead by one point over Team USA heading to Sunday. Team USA needs to score 13 points to retain the Cup. GB&I hasn’t won the Walker Cup in the last 11 years. Interestingly enough, Cowan will face Donegan again on Sunday morning foursomes. It remains to be seen if the 21-year-old can turn the tide this time around.
