The 20-year-old Ping wedges with square-shaped grooves will no longer be allowed on the PGA Tour starting March 29 after an agreement reached Monday with Ping executives to waive its right that kept the PGA Tour from banning Ping Eye2 wedges made before April 1, 1990. The Ping Eye2 wedges have deeper, wide grooves no longer allowed under new USGA regulations.
