The No. 32 seed beat the No. 1 seed. Twelve hours after they chipped in to force a playoff, Wisconsin teammates Jacob Beckman and Charlie Erlandson knocked out medalists Liam Eyer and Kailer Stone in the Round of 32 at the U.S. Amateur Four-Ball — becoming the fourth No. 32 seed in championship history to topple a top seed.

SCOTTSDALE, Ariz. — Jacob Beckman and Charlie Erlandson, University of Wisconsin teammates and the last sides into the Round of 32 via Monday morning’s 8-for-3 playoff, eliminated medalists Liam Eyer and Kailer Stone 1-up in the marquee match of the opening round of bracket play Monday at Desert Mountain Club. Beckman chipped in for birdie on the 18th hole at Cochise late Sunday afternoon to force the playoff; Erlandson snapped his driver on the par-5 15th during the R32 match and finished the round without it. Eight birdies and a clutch finish later, they’re in the final 16.

The medalist upset was the headline, but it wasn’t the only Monday shock. Welsh duo Jonathan Bale and Tomi Bowen (No. 29 seed) eliminated 2024 semifinalists Will Davenport and Mike Smith (No. 4) 1-up despite a five-birdie best-ball 65 from the Floridians. Hong Kong 16-year-olds William Lisle and Darren Zhou (No. 28) took out No. 5 seed Jared Abercrombie and Max Emberson 1-up in another bottom-seed upset. And in a battle of past champions, 2024 winners Brian Blanchard and Sam Engel ousted 2022 champs Chad Wilfong and Davis Womble 2-and-1.

The Round of 16 begins Tuesday at 7 a.m. MST at Cochise, with quarterfinal matches scheduled for 1 p.m. The semifinals and 18-hole championship match are Wednesday. Sixteen sides remain.

Five Stories from the Round of 32

Round of 16: Tuesday’s Bracket

First match 7 a.m. MST · First quarterfinal 1 p.m. · All at Cochise

Tuesday’s storyline matchups

• Bale/Bowen vs Colton/Mawhinney. The Welsh duo just took out the No. 4 seed. The defending champion is on the other side of the match. If Mawhinney is going to make history, he has to get past the hottest international side in the bracket first.
• Long brothers vs Beck/Walters. Last-minute alternates against the 2025 runners-up. The Longs got the call on May 7. Beck has a 2024 U.S. Mid-Amateur title and a 10-4 career match-play record at this championship. Strongest mismatch on the bracket on paper; most dangerous lower-seed storyline in practice.
• Healy/Larkin vs Blanchard/Engel. A USGA champion is caddying for his son against the most recent U.S. Amateur Four-Ball champions. Larkin Sr. won the 1979 U.S. Junior Amateur. His son and Zach Healy ham-and-egged their way to a 19-hole win Monday. Blanchard and Engel just took out the 2022 champions in a clinic.
• Hong Kong vs Edwards/Parker. Sixteen-year-olds William Lisle and Darren Zhou are the story of the bracket, eliminating two top-half seeds on their way to a R16 date with the duo that survived Monday’s 20-hole marathon.
• Kittleson/Stoltz vs Fitzgerald/Hamel. The hometown twice-runners-up against the Charlotte duo that beat Lawrence Allan and Grady Brame in 19 holes Monday afternoon. Kittleson and Stoltz survived a fright Monday morning against the No. 31 seed; they don’t get to coast Tuesday either.

Sides Eliminated Monday of Note
