The Putt That Lipped Out on Medinah's 18th: What the 3-2 Presidents Cup Scoreboard Hides

Hook: Two 40-Footers, Two Different Outcomes

Last night I sat in the second tier behind Medinah Country Club's 18th green, and I was not watching the ball. I was watching the tempo of Im Sung-jae's putting stroke while a shot tracker refreshed every thirty seconds. The number that stung me most at the end of the session was not a drive and not a long iron. It was the 17th green. Im's 40-foot birdie putt ran 15 feet past, the bogey came, and the Internationals' lead went with it. One hole later another 40-footer grazed the lip — the putt that would have salvaged half a point. The scoreboard read 3-2 to the United States. My notebook read something different: on the same day, at the same green speed, off the same two hands, one putt finished 15 feet long and one finished a millimetre short. Both outcomes will be recorded in digits. The match itself was being decided on quieter layers.

Context: Establish the Data Provenance First

The Presidents Cup is a biennial team event — the United States against an International team drawn from the rest of the world outside Europe. The 2026 edition is at Medinah Country Club in Illinois. The structure matters: five four-ball (better-ball) matches in Thursday's opening session, five foursomes on Friday, and captain Brandt Snedeker's remark that there are "four more to go" tells you the week is a five-session marathon, not a sprint. International captain Stuart Ogilvy noted that his players now have a round under their belt. Both camps are saying the same thing: one session proves nothing.

I am leading with provenance because without it the rest of this analysis hangs in the air. There is no ShotLink data in my hands, no Strokes Gained table, no green-slope map. What exists is shot-by-shot description, quotes from captains and players, and specific hole references — the par-4 fifth, the par-5 sixth, the par-3 13th. The sample is one session, five matches, at most 90 holes. Anyone drawing "who is in form" conclusions from that is telling a story, not reading statistics. So I will pre-register my failure modes, as I do in every preview. One: putting variance across a single session is high enough that no back-nine verdict survives it. Two: the "format specialist" label here is born from seven matches. Three: I have seen only the tracker and the broadcast feed, and the gap between a walking scorer's card and a television graphic is a thing I can currently only partially verify.

Core: Five Matches, Three Turning Points, One Unfinished Ledger

The first match was the most expensive of the session. Scottie Scheffler and Sam Burns had played four matches together before Thursday for zero wins, three losses and a half. Last night that pairing won a point for the first time. The match was effectively settled on the 14th, where Burns's approach finished two feet from the hole — the shot Scheffler called the best of the match. Then on 18 Scheffler's bunker shot came out to tap-in range for the clinching par save. This is the classic match-play pattern: a side can lose the aggregate statistics and still buy an entire point with one swing.

The real information sits on the other side of that match. Im Sung-jae and Min Woo Lee missed three consecutive birdie chances from roughly 10 feet. In four-ball, that is not a small thing. A currency conversion is required here, and I will state it explicitly so nobody forgets I am borrowing a term: birdie count in better-ball is roughly the golf equivalent of chances created, and three birdies from two players is something like 0.6 xG of attacking output — the number does not look disastrous, but it does not win. The Conners/Echavarria session should be read the same way: three birdies in better-ball is a forward passing at roughly fifty per cent.

The second turning point is 21-year-old Jackson Koivun. He turned professional about three months ago, won his first PGA Tour title at the 3M Open in only his third start, won an NCAA team title with Auburn in June, and became the first player to win a Walker Cup point and a Presidents Cup point just over a year apart. His session was not clean: his second tee shot went out of bounds. That is where the four-ball mechanism becomes visible — when a partner covers the gap, talent gets more valuable and the risk gets better hidden at the same time. Justin Thomas rescued him from a bunker, and Thomas's Presidents Cup four-ball record now stands at 7-0-0. I respect the record; I am cautious about the tag.

Koivun himself admitted his start was shaky. His wedge on the par-5 sixth finished seven feet from the hole, meaning his short game did more work than his long game on day one. In football-analytics language, he is the player with good positioning and unstable finishing — entirely normal at 21.

In the third match, Collin Morikawa and Wyndham Clark won 3-and-2 and never trailed. That is the quietest and most valuable data point of the session: in four-ball, when a pair never trails, it means the two players' bad shots did not land on the same hole. In the fourth, Xander Schauffele and Cameron Young lost, having won only the par-4 second. Across five matches, that is the one pairing decision most likely to change on Friday.

The fifth match matters beyond the competition. Hideki Matsuyama and Hisatsune played together — the first time two Japanese golfers have appeared in the same Presidents Cup since 2026. The International strategy is clear: build depth from non-traditional pipelines. One structural fact belongs here too. The United States has won the opening session in nine of the last ten Presidents Cups and has now won ten in a row outright. A 3-2 lead is not an aberration; it is the normal output of a long-standing structure.

Contrarian Angle: Correlation Is Not Causation

Thomas's 7-0-0 four-ball record is a wonderful story made of seven matches. Opponent quality, partner quality, Medinah's wind — none of it is controlled. I will not label anyone a format specialist on seven data points; I will say the pairing deserves a repeat test. By the same logic, Im's back-nine putting collapse and Burns's clutch putting are both single-session samples. The spreadsheet is a monastery, but reading half a spreadsheet is a confession of laziness.

One more thing, because it is my old trade. Live scoring and broadcast graphics are two different sports wearing the same leaderboard. A walking scorer's card and a television graphic can tell different stories about the same hole, and the market follows whichever travels faster. The distance between the information that reaches the market and the information that happens on the course is invisible unless you are standing there. What was visible last night was three missed 10-footers. That is not a model. That is a putt.

Takeaway: Friday Foursomes Is a Different Game

Friday brings five foursomes matches — one ball, alternate shots. Inside professional golf this is almost a separate sport, where the biggest skill is not the drive but the decision about who plays the next shot. Until the Internationals start holing putts inside 10 feet on the back nine, a 3-2 margin is a one-point margin, and one and a half sessions can flip it.
