PLAYER NOTES:  

Evan Beck, 34, of Virginia Beach, Va., the 2024 U.S. Mid-Amateur champion, claimed his elusive USGA title with an impressive 9-and-8 victory over Bobby Massa in the final at Kinloch Golf Club, in his home state of Virginia. He avenged his runner-up finished a year earlier to Stewart Hagestad at Sleepy Hollow, in Scarborough, N.Y. Beck also finished runner up in the 2008 U.S. Junior Amateur at Shoal Creek, defeating future three-time major champion and two-time U.S. Junior Amateur champ Jordan Spieth in the semifinals after getting into the field as an alternate. He was a four-year letter-winner at Wake Forest as well as an All-Atlantic Coast Conference performer and All-American. 

Hamilton Coleman, 17, of Augusta, Ga., earned his spot at The Olympic Club following his victory in the 2025 U.S. Junior Amateur at Trinity Forest Golf Club last month in Dallas, Texas. Coleman needed 25 holes – the longest U.S. Junior Amateur match in 23 years – to oust his Round-of-64 opponent before advancing to the 36-hole championship match, where he took down world No. 52 Minh Nguyen, of Vietnam, 2 and 1. A future University of Georgia Bulldog, Coleman won the 2024 Junior Players Championship and competed in the 2025 Wyndham Cup. Coleman, a member of the U.S. National Development Program’s Georgia State Team, also earned exemptions into the 2026 U.S. Open at Shinnecock Hills Golf Club and the 2026 U.S. Amateur at Merion Golf Club following his victory at Trinity Forest.  

Luke Colton, 18, of Frisco, Texas, will be competing in his sixth USGA championship and third straight U.S. Amateur. Colton made it to the Round of 32 in the 2023 U.S. Junior Amateur and the Round 16 in the 2024 U.S. Junior Amateur. The left-hander won the Terra Cotta Invitational in 2024 at Naples National Golf Club and successfully defended his title this past April. In 2024, he won the Byron Nelson Junior Tournament and was runner-up in the Rolex Tournament of Champions as well as the Texas State Amateur. That same year he made it to the Round of 16 in the North & South Amateur at Pinehurst and represented the United States in the 2024 Junior Presidents Cup. The Vanderbilt commit for the Class of 2026 won the 2024 and 2025 Texas 5A high school state championships. Colton was named to the U.S. National Junior Team earlier this year. 

John Daly II, 22, of Dardanelle, Ark., won the 2025 Southern Amateur Championship by five strokes at Blessings Golf Club in Johnson, Ark. Earlier this spring, Daly II picked up his first collegiate win for the Razorbacks at the Columbia Spring Invitational, playing the final five holes in 6 under par to win. A rising redshirt senior at the University of Arkansas, Daly II is the son of two-time major champion John Daly. This past season, Daly II compiled a team-low 72.21 scoring average. The younger Daly also finished third at this year’s Northeast Amateur. This will be Daly’s third USGA championship as he competed at last year’s U.S. Amateur at Hazeltine and the 2021 U.S. Junior Amateur at The Country Club of North Carolina. Daly’s father played in the 1998 U.S. Open at Olympic Club, making the cut and finishing T-53. 

Jaden Dumdumaya, 19, of Benicia, Calif., is coming off a victory at the 58th Pacific Coast Amateur in July. He entered the final round two strokes back and fired a 3-under 68 with four birdies to secure the title. A rising sophomore at the University of Southern California, Dumdumaya joined the Trojans after a decorated high school career at De La Salle High School, where his team won the East Bay Athletic League Championship, Champions Invitational, CIF NorCal Section and the 2022 and 2023 CIF State Championships. He holds the record for most wins on the Junior Tour of California, surpassing two-time U.S. Open champion Bryson DeChambeau and Justin Suh. Dumdumaya was named the 2023 Philippine National Men’s Golf Player and represented his country at the 32nd Southeast Asian Games. 

Ethan Fang, 20, of Plano, Texas, captured the 130th Amateur Championship at Royal St. George’s, in England, becoming the first American in 18 years (Drew Weaver) to win the oldest amateur competition. The rising junior helped Oklahoma State claim the 2025 NCAA Division I title, posting a 2-1 record in match play, including a 1-up victory over Bryan Lee, of Virginia, in the championship match. Fang advanced to the quarterfinals of the 2024 U.S. Amateur at Hazeltine National and reached the Round of 16 at the 2022 U.S. Junior Amateur at Bandon Dunes.

Goode is in his fifth year at the University of Washington, having just earned a scholarship on the men’s golf team this offseason. The George Washington High School product claimed the 2024 Silverado Amateur Championship, finished third at the 2024 NCGA Stroke Play Championship and made the Round of 16 at the San Francisco City Men’s Championship. This will be Goode’s second U.S. Amateur appearance. He qualified for the 2023 U.S. Amateur at Cherry Hills Country Club. 

Dean, 22, and Reed Greyserman, 20, of Short Hills, N.J., and Boca Raton, Fla., are brothers who both earned their way into the field by winning championships conducted by Allied Golf Associations. Dean, with Reed serving as his caddie, won the 123rd Met Amateur Championship at The Bedens Brook Club in New Jersey. A rising senior at Stanford University, Dean will be competing in his second USGA championship. Younger brother Reed, a rising sophomore at Princeton University, won the 108th Florida State Amateur Championship after carding a final-round 4-under 68 before prevailing on the first playoff hole. He will be playing in his fourth USGA championship. Golf runs deep in the Greyserman household, as eldest brother Max is a regular on the PGA Tour. Their mom competed in the 2nd U.S. Adaptive Open at Pinehurst No. 6. 

Trevor Gutschewski, 18, of Omaha, Neb., an incoming freshman at the University of Florida, won the 2024 U.S. Junior Amateur after defeating medalist Blades Brown in the Round of 32 and Tyler Watts in the 36-hole final at Oakland Hills Country Club (South Course). The victory punched his ticket to the 125th U.S. Open in Oakmont where he failed to make the cut. This past June, Gutschewski claimed the Western Junior Championship at The Harvester Club, in Rhodes, Iowa. His father, Scott, owns three Korn Ferry Tour victories and splits time between that circuit and the PGA Tour. Gutschewski, his father, and older brother, Luke (Iowa State), all teed it up together in the Korn Ferry Tour's Pinnacle Bank Championship, the first time in 20 years that a father and two sons were in the same event under the PGA Tour umbrella. This will be his fifth USGA championship. 

Stewart Hagestad, 34, of Newport Beach, Calif., won his third U.S. Mid-Amateur title in 2023, defeating Evan Beck, 3 and 2, at Sleepy Hollow Country Club. He has been a member of four winning USA Walker Cup Teams (2017, 2019, 2021, 2023). Hagestad, who has competed in five U.S. Opens, reached the quarterfinals of both the 2020 and 2022 U.S. Amateurs, losing to the eventual champion both times (Tyler Strafaci and Sam Bennett). He has played in 32 USGA championships, including 15 U.S. Amateurs. He captured the 2021 U.S. Mid-Amateur Championship at Sankaty Head Golf Club, defeating Mark Costanza, 2 and 1. He also defeated Scott Harvey in 37 holes in the 2016 U.S. Mid-Amateur Championship, producing the largest comeback victory since a 36-hole final was introduced in 2001. Hagestad was the low amateur in the 2017 Masters Tournament, becoming the first invited Mid-Amateur champion to make the 36-hole cut. 

Will Hartman, 19, of Charlotte, N.C., secured an exemption into the championship by claiming the 2025 U.S. Four-Ball Championship title with partner Tyler Mawhinney at Plainfield Country Club, in New Jersey in May. The duo defeated reigning U.S. Mid-Amateur champion Evan Beck and Dan Walters, 3 and 1, in the 18-hole final. With the victory, Hartman and Mawhinney cemented their names in history as the first male players from the U.S. National Development Program to claim a USGA championship. The 2025 incoming Vanderbilt freshman reached the semifinals of the 2023 U.S. Junior Amateur and returned to compete again in 2024. 

Avinash Iyer, 21, of San Ramon, Calif., is a rising junior at San Jose State University. After splitting his time between soccer and golf during his elementary years, he decided to focus on golf exclusively beginning in high school. During his sophomore season, he suffered a torn labrum, putting his career on pause. After being told by doctors to completely stop playing golf and being frustrated with his rehab, Iyer took his recovery into his own hands and created his own exercise plan. After countless hours of training and therapy, he made a full recovery and reached his goal of playing Division I golf at San Jose State. Iyer also competed in the 2022 U.S. Junior Amateur.  

Ben James, 22, of Milford, Conn., is a three-time first-team All-American at the University of Virginia and recently led the Cavaliers to a runner-up finish in the NCAA Championship.

He also represented the United States on the 2023 and 2024 Palmer Cup Teams. He advanced to the quarterfinals of the 2023 U.S. Amateur, losing to Parker Bell in 19 holes, and lost in the Round of 64 of the 2024 championship to eventual winner Jose Luis Ballester. James tied for 33rd in the 2025 Valero Texas Open, getting into the PGA Tour event by capturing the Valero Texas Collegiate. 

Filip Jakubcik, 21 of Czechia, is No. 5 in the WAGR and will be a senior at the University of Arizona in the fall. Jakubcik earned First Team All-Big 12 honors during his junior season with the Wildcats after posting the team’s best scoring average (71.00) and winning the Western Intercollegiate for a second consecutive year.
