Understanding the Unique Setup of the 9th Green at Oakmont Country Club: A Closer Look at the 2025 U.S. Open Practice Sessions

By Alan Bastable | June 10, 2025

The 2025 U.S. Open at Oakmont Country Club has drawn attention not just for its prestigious history but also for its unique practice green structure. Nestled behind the clubhouse, the back half of the 9th green is positioned to function as a practice area for players, presenting a one-of-a-kind opportunity for preparation in a major championship setting.

An Overview of the 9th Green

Contrary to what many may assume, this area adjacent to the clubhouse is not merely a practice green. It serves as an integral part of the official playing surface for the tournament, specifically designed for players to hone their putting skills. Craig Winter, the USGA’s senior director for rules of golf and amateur status, emphasized the importance of this distinction during a briefing. Using the 9th green in this manner allows players to practice without the penalties typically associated with practice greens on tournament days.

Implications for Tournament Play

The setup offers significant advantages for the players. For instance, should a competitor’s ball land in the practice holes on this section of the green after a lengthy approach shot, they face no penalty and can simply putt away from the area. Should the ball inadvertently drop into a practice hole, the player is entitled to relief, as Winter clarified: “Ground under repair” applies here, allowing the player to place their ball at the nearest point of relief.

The Dynamics of Practice Day

On a busy practice day, players were observed utilizing the expansive 9th green to its fullest. Measuring 70 feet in length and covering over 20,000 square feet, the green accommodates multiple players and caddies. Surrounded by agents and media personnel, the scene presented a unique blend of competitive atmosphere and camaraderie, showcasing the high-stakes nature of the U.S. Open.

Signage and Rules Clarity

Detailed signage surrounds the green, instructing players on the operational nuances. “This entire green is the 9th putting green,” read the notices. This simple yet important clarification delineates the boundaries for practice sessions, marked by blue stakes and a dotted line. Observers noted the care taken in setting these parameters to maintain fair play and formalize the practice session’s structure.

Managing Competitive Fairness

One of the more intriguing aspects of this format is how closely it aligns with the regulations governing play. As Winter pointed out, any intentional attempt to practice on the front section of the green during the tournament could result in serious penalties, including disqualification. The split green thus introduces an extra layer of strategy, as players must navigate their practice without accidentally crossing these invisible lines.

Addressing the Anomalies

While players are restricted from measuring green conditions on the lower half, they are permitted to do so on the back half. This quirky regulation adds to the complexity of the situation, making it both a fascinating and specialized experience for participants and their teams. Players must remain aware of these rules to effectively change their strategy according to the unique playing conditions.

The Atmosphere of Anticipation

As practice rounds began, the excitement in the air was palpable. Observations of professionals honing their craft on hallowed ground contributed to a charged atmosphere, as fans and media absorbed the nuances of the players’ techniques. The juxtaposition of elite-level competition in such a unique setting created a lively scene for everyone involved.

The Future of Golf Practices

The innovative practice approach at Oakmont could set a precedent for future championships. As golf continues to evolve, understanding how best to integrate traditional rules with modern practices will become increasingly important. Observations from this year’s U.S. Open might inspire adjustments in how tournaments utilize practice greens.

Conclusion: A Unique Competitive Edge

In summary, the modified practice environment at Oakmont Country Club presents exceptional opportunities and challenges for players during the 2025 U.S. Open. From the strategic rules governing practice to the expansive layout of the 9th green, this tournament showcases the intricacies of professional golf. The successful execution of this setup not only enhances players’ preparation but could also influence the structure of future tournaments, ensuring that the sport maintains its rich traditions while adapting to contemporary needs.

As this year’s championship unfolds, all eyes will be on the 9th green—both as a key component of the course and a fascinating study in the blend of innovation and tradition in golf.
