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.

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.

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.
