“The U.S. Amateur Four-Ball Championships represent the USGA’s commitment to support and advance amateur competition,” said Daniel B. Burton, USGA vice president and Championship Committee chairman. “This format is broadly popular in all 50 states and at golf clubs nationwide and should produce spirited team play, camaraderie and enjoyment for both the players and spectators.”

The 2015 U.S. Amateur Four-Ball is scheduled for May 2-6, with both the Lake and Ocean courses at The Olympic Club set to host 36-hole stroke-play qualifying.
