As part of the USGA's continuing commitment to inform and educate on the Rules of Golf, the resources below will assist tournament administrators and golfers in complying with amended golf-club groove regulations when the Condition of Competition is in effect.
The optional groove regulations, which apply to all clubs except drivers and putters, are in effect for all USGA championships, including qualifiers. This optional Condition of Competition is recommended only for events played at the very highest level of amateur involving expert players. (See Decision 4-1/1 of the Decisions on the Rules of Golf).
