U.S. Junior Amateur competitor forced out after controversial disqualification
James Nagle’s championship ended after officials reviewed an incident during his opening round at Saucon Valley.
Florida golfer James Nagle was disqualified from the U.S. Junior Amateur Championship on Monday after officials ruled he had breached the USGA’s green-reading regulations during the opening round at Saucon Valley Country Club.
Nagle, a rising high-school senior from Ponte Vedra Beach and a verbal commit to the University of South Florida, was removed from the championship after officials determined he had committed multiple violations of Model Local Rule G-12 during his first-round 6-over 76 on the Grace Course.
The rule, which was introduced for USGA championships and selected elite amateur events in 2023, prohibits players from using any written, printed, electronic or digital material to help read their line of play for strokes made on the putting green.
It goes further than the existing Rule 4.3a/1, which limits the size and detail of green maps and similar putting information players can use during a round.
The USGA says G-12 is designed to place greater emphasis on a player’s own ability to read greens, ensuring that putting remains a key skill rather than something that can be enhanced through detailed external information.
The first violation of G-12 results in a two-stroke penalty in stroke play, while any subsequent breach leads to disqualification.
Nagle later explained the circumstances behind the ruling in a social-media post, saying he was unaware that yardage books containing green maps were not permitted to be used while on the putting surface.
“I was not informed on the fact yardage books with green maps were not permitted to use while on the putting surface,” Nagle said.
He added that his playing partner warned him about the restriction during the round, prompting him to immediately speak with a rules official.
“My playing partner warned me that it wasn’t allowed. So, I went to the nearest rules official and explained the situation.”
Nagle said officials allowed him to complete his round while they reviewed the incident.
“They told me to finish the round while they reviewed the situation.”
After completing his round, officials asked Nagle whether he had used the material more than once and whether it was specifically being used to gain green information.
After confirming both points, he was disqualified from the 2026 U.S. Junior Amateur.
G-12 is not currently used in many other junior and college events, including American Junior Golf Association competitions, meaning some players may be less familiar with the stricter regulation.
The PGA Tour also does not use G-12, instead operating under Model Local Rule G-11, which allows committee-approved yardage books with restrictions on green-map detail and handwritten notes.
The USGA provides competitors in its championships with an explanation of G-12 before play begins, while also making clear that players are responsible for their caddies’ actions under the rule.
Nagle’s DQ marks the second consecutive year a player has been forced out of the U.S. Junior Amateur following a rules violation.
At the 2025 championship at Trinity Forest, 17-year-old Banks Steele was disqualified after officials determined his caddie had twice attempted to measure wind conditions by throwing a hat into the air, a breach of Rule 4.3a(2).
Nagle, currently ranked No. 318 in the AJGA rankings, is a player some golf fans may recognise after appearing in a 2022 Good Good YouTube video alongside Garrett Clark, Grant Horvat and PGA Tour winner Akshay Bhatia.
The Florida junior entered the championship looking to test himself against one of the strongest fields in junior golf, but his tournament ended after one round following the rules decision.
The 2026 U.S. Junior Amateur features 264 competitors battling through two rounds of stroke play at Saucon Valley’s Old Course and Grace Course.
Following 36 holes, the top 64 players will advance to match play, with the championship concluding with a 36-hole final on Saturday.
Among those competing is Charlie Woods, son of 15-time major champion Tiger Woods, who opened with a 5-over 76 and faces a battle to make the match-play cut.
The U.S. Junior Amateur remains one of the most prestigious events in junior golf, with former champions including Tiger Woods, Jordan Spieth, Scottie Scheffler, Brian Harman, David Duval, Johnny Miller and Will Zalatoris.
Woods famously won the title three consecutive years from 1991-93, leading the USGA to rename the championship trophy the Tiger Woods Trophy in recognition of his historic achievement.

Nagle’s disqualification serves as another reminder of the importance of understanding the increasingly detailed rules surrounding modern competitive golf, where even an unfamiliar local rule can have a major impact on a player’s tournament.
