MAMARONECK, N.Y. — Mark Costanza and Jeronimo Esteve of Isleworth Country Club are the 2026 Anderson Memorial Four-Ball champions, closing out Hudson National's Michael Cavaliere and Michael Minerva Jr., 3 and 2, in Sunday's championship match on Winged Foot's West Course. The victory capped a grinding three-day march through one of amateur golf's most demanding match-play fields.
Costanza and Esteve earned the final with the week's hardest day's work, outlasting Capital City Club's Brown and Wyatt in a marathon semifinal that stretched to the 22nd hole — four holes beyond regulation — before reaching the championship match. There they ran into the tournament's improbable story and ended it.
The Cinderella run stops one win short
Cavaliere and Minerva Jr. had needed a playoff merely to claim the 16th and final spot in the Championship bracket, then authored the run of the week. As the lowest seed, they upset medalist Goldstein and Buttacavoli of La Gorce in the round of 16, dispatched Albers and McGhee of Mission Hills in the quarterfinals, and beat Sigler and Cassini of Atlanta Athletic, 3 and 2, in Sunday morning's semifinal to reach the final. The bid for a storybook title fell two holes short against Costanza and Esteve.

Senior Division: a new champion at Pine Valley
The Senior Division produced first-time winners in Seth Sargent and Eoghan O'Connell of Pine Valley Golf Club, who closed out a strong week to claim the 2026 title. Their path included a 5-and-4 semifinal dismissal of defending champions Goodwin and Peck of Golf Clubs at The Tribute, guaranteeing a new name on the trophy. In the other half, McCoy and Gerwin of Seminole — last year's runners-up — advanced past the host club's Staudinger and Meyer, 5 and 3, before falling in the final.

About the Anderson Memorial
Created in 1933 to honor Winged Foot founding member and two-time U.S. Amateur runner-up John G. Anderson, the tournament pairs 36 holes of stroke-play qualifying with three days of match play in both Championship and Senior divisions. The West Course, a 1923 A.W. Tillinghast design and five-time U.S. Open host, examines every facet of the game with its punishing rough, deep bunkers, and severely contoured greens. This year it rewarded survival over seeding: a team that took a playoff just to make the field reached the final, and the eventual champions, Costanza and Esteve, earned their crown only after surviving four extra holes in the semifinals. With invitations limited and the field drawn from premier clubs nationwide, the Anderson Memorial remains a defining event on the amateur calendar, where history, tradition, and championship golf converge each June.
