Developing Snedeker's Arithmetic Is Right and His Conclusion Is Wrong — 5-0 Changed the Required Rate, Not Just the Scoreboard

Five matches went out at Medinah on Friday afternoon and five matches came back International. Matsuyama and Sungjae Im beat Russell Henley and Jacob Bridgeman 3 and 2. Adam Scott and Christiaan Bezuidenhout beat Justin Thomas and Cameron Young by the same margin. Ryan Fox and Min Woo Lee got Collin Morikawa and Wyndham Clark 1 up. Si Woo Kim and Tom Kim took Patrick Cantlay and Xander Schauffele 4 and 3. And Corey Conners and Nick Taylor beat Scottie Scheffler and Sam Burns, 1 up, on a putt Taylor described without much ceremony: "Fortunate there that Sam's lipped out."

Internationals 7, United States 3.

Brandt Snedeker's response was the right one for a captain to give. "This thing is 35, 40 percent over," he said. "It's not even halftime of a football game. There's a lot of golf left."

He is not wrong about the fraction. Thirty points are available; ten have been played. Eight matches go out Saturday, four four-ball and four foursomes, and twelve singles follow on Sunday. Two thirds of the cup is unplayed.

What the fraction hides

Convert it into the number that actually governs a match-play weekend, which is the rate each side needs from here.

Fifteen and a half points wins the Presidents Cup. The Internationals have seven, so they need 8.5 of the remaining 20 — 42.5 per cent. The United States has three and needs 12.5 of 20, or 62.5 per cent. That is the gap. Not four points. Twenty percentage points of required win rate, against a field where the two teams have been splitting sessions 3-2 and 5-0.

For the Americans to hit 62.5 per cent across eight team matches and twelve singles, they need something close to a 12-8 weekend. They have not had a session like that yet this week. They had one session at 3-2 and one at 0-5.

The number Snedeker gave is a true statement about how much golf remains. It is not a statement about the position, and every captain in the history of the event has made the same substitution on purpose.

The last team to do this lost

Here is the strongest argument against reading Friday as decisive, and it is a good one, because it happened two years ago.

The Internationals swept the foursomes session at the 2024 Presidents Cup. They lost the cup. Friday's result was only the seventh session sweep in the event's history, and the first time a team has done it in consecutive editions — which means the single most recent precedent for exactly this is a team that produced exactly this and did not win.

The venue argues the same way. Medinah is where Europe erased a 10-6 deficit on the final day of the 2012 Ryder Cup. That is a bigger hole than the one the United States is in, closed on the same property, in the same format, on a Sunday. If you want a reason to think four points is survivable, you do not need a theory. You need a map of the golf course.

There is a second, quieter argument for the Americans. Foursomes is the format most sensitive to pairing chemistry and least sensitive to raw quality, because alternate shot punishes one bad swing from either player and gives the better player no way to rescue the hole. Two of Friday's five went the full distance and were won 1 up, including Conners and Taylor over Scheffler and Burns, which turned on a lip-out. Two more finished 3 and 2, on the 16th green. Only the Kims' 4-and-3 win over Cantlay and Schauffele was over early. A 5-0 session containing two one-hole margins is not a rout in any sense except the one that counts.

We take the point. We would still rather have the seven.

The detail nobody planned for

There is an odd symmetry to how the Americans got here, and it runs through our coverage of this week.

On Wednesday Snedeker said the setup he had specified for Medinah "has not gone according to plan" — he wanted a firm, running golf course where the ball bounced and the slopes did the work, and ten days of rain took it away from him. The captain's setup is the one real lever a home side controls, and it got rained off.

Meanwhile the man on the other side of the first tee, Geoff Ogilvy, helped redesign this golf course. He also grew up on the Melbourne sandbelt at Royal Melbourne, where the Internationals won the only Presidents Cup they have ever won, in 1998, by nine points. Ogilvy's picks on September 1 were Conners, Nico Echavarria, Im, Ryo Hisatsune, Taylor and Bezuidenhout. Four of those six played Friday. All four won.

So the softest version of Medinah is being played by a team whose captain knows the drawing, against a team whose captain asked for the opposite conditions and did not get them. We are not going to claim the rain caused a 5-0. Alternate shot does not work that way, and neither does Scottie Scheffler losing a match. But the one variable the home captain was supposed to own was taken off him before the first ball, and the man who knows the greens best is wearing the other shirt.

What the 7-3 actually equals

The four-point lead ties the largest the Internationals have ever held after two sessions. The only other time was 1998, and that is the only one of these they have ever won.

That is a genuinely striking fact and it is also a sample of one. The United States is 13-1-1 in this event with ten straight wins, which is the most durable pattern in team golf and has survived deficits before. The base rate says the Americans come back. Friday says something is different this time.

We do not know which of those is the better guide, and anyone who says they do is guessing. What we can say is narrower and firmer: the required rate is now 62.5 per cent for the United States, two of Friday's five went to the last green and both went International, and the most recent team to sweep a foursomes session at this event went on to lose it.

Saturday's eight matches will settle whether Friday was a session or a turn. If the Americans do not take at least five of them, the arithmetic Snedeker is leaning on stops being a comfort and starts being a problem.
