In Local (first stage) and Sectional (second stage) Qualifying as well as in the Championship proper, the player’s clubs must conform to the groove specifications in the Rules of Golf effective January 1, 2010. Note: Ping EYE2 clubs manufactured prior to April 1990 may not be used during Local and sectional qualifying as well as the Championship proper. The Condition of Competition is available for review on the entry application.
The USGA and R&A have created a reference resource called the Informational Database to assist golfers in determining whether their irons, hybrids and fairway woods comply with the New Groove Rules. For information about and to access the database, please use the following link: http://www.usga.org/InfoClubsDB/intro.html. Additionally, for information regarding the conformance status of clubs not listed, please contact the USGA Research And Test Center at (908) 234-2300.
Player Club Testing is available for the 2011 U.S. Open, U.S. Women’s Open and U.S. Senior Open Championships. Please use the following link:

The USGA strongly suggests that all players verify the conformance of their clubs well in advance of their scheduled qualifying competition. It is the player’s responsibility, not the USGA’s responsibility to ensure that his clubs conform. Waiting until the day of the competition is the fault of the player. The Committee is under no obligation to test the club. The competitor may play. However, if it is later determined that the club is non-conforming, including after the competition has closed, the player will be disqualified.
