The Arc: the John Deere Classic

We commit a calibrated win-probability on every player before the first tee, then come back after and show you — honestly — where we were right and where we got humbled. Here is the 2026 John Deere Classic, told through the live win-probabilities that moved all week.

Four days ago we published a win-probability on every player at TPC Deere Run — before a shot was struck. Now the honest part. Chris Gotterup won the 2026 John Deere Classic, closing with a 9-under final round to reach 20-under and win by one over Max Homa. What makes it land for us: Gotterup started Sunday at just a 2.0% live win-probability — T12, several back — and the highest number on our pre-tournament board all week was his, at 5.6%. Our board rated him first; the Sunday charge is what turned that number into a trophy.

Before the first tee we published The Read: the John Deere Classic. This is the honest close of that loop — graded against the exact board we committed to.

Act I - the winner's arc

Gotterup's week, round by round: −5, −3, −3, −9 — steady, then a closing 9-under that was his biggest round of the week. He entered the final round at a 2.0% win-probability and well off the lead; after his birdie on 17 moved him from 19-under to 20-under, the live win-probability we track rose from 36.4% to 64.6%. It resolved to 100% once the final result was known. The data signature: +6.96 true strokes-gained on Sunday alone — his biggest round — and +13.2 for the week. And the honest twist: our own form note doubted him, calling him top of the board "on ceiling, not recent results" off finishes of T30, T43, T27, T10, T14. The week answered the question.

Act II - the Sunday swing

The single most dramatic win-prob move of the week was Gotterup's own final round: from 2.0% at the Sunday tee to 100% once the result was final. The shot-linked inflection came at 17, where his birdie lifted the live win-probability we track from 36.4% to 64.6% as he reached 20-under at TPC Deere Run.

The near-misses

Plenty of you had these names on a slip, so we tell it straight, not smug.

• Max Homa — the runner-up, alone in second at 19-under, one shy. He closed hard and pushed it to the last — after Gotterup posted 20-under, the model still gave the chasers a real look before Homa's bid fell one short.
• Lucas Glover — out fast with an 8-under Thursday that briefly put him top of the leaderboard, then a −6 Friday kept him in it; but a flat weekend (−2, −2) settled him into a share of third at 18-under. The early number was real; the finishing gear wasn't there.

Act III - read vs. reality

This is the part most outlets skip. We don't. Every line here is a model estimate measured against what actually happened — not betting advice, and not a guarantee of anything.

• What we got right: our number-one favorite won. Chris Gotterup sat at the top of our published board (5.6%) before the first tee and finished the week holding the trophy — the cleanest kind of hit, the board's highest-rated player winning outright.
• Where the board got humbled: the runner-up wasn't on our board at all. Max Homa — who pushed Gotterup to the final hole and finished solo second at 19-under — did not appear among our eight published favorites. We're not quoting a standardized surprise score here — we didn't persist a calibrated pre-event number for Homa, so we won't invent one.
• The storyline that played: in the Read we framed Gotterup as ceiling over form — our board rating his upside while his last five results raised the question. That storyline played straight: the ceiling showed up.
• Calibration note — a mixed board, honestly. The top of it nailed the winner, but the rest never seriously contended. Our co-favorite Ben Griffin (5.5%), the form we called "arriving hottest," finished well back at 13-under; Keegan Bradley (3.9%) made the cut but stalled at 12-under; Keith Mitchell (3.5%) at 8-under. The one board name to miss the weekend was Jackson Koivun (3.1%). The board found the champion and misjudged the chase.

What's next

That's the arc — our board earned the big one and gave some back in the middle, and you saw the receipts either way. Next up: The Read on our next event, where we publish our win-prob favorites before the first tee and do it all over again.
