Golf: Ping controversy widens

Ping chairman John Solheim reminded the US PGA Tour yesterday that it cannot make a separate rule to ban Ping Eye2 wedges, the 20-year-old clubs that led Scott McCarron to claim Phil Mickelson is "cheating" by using them.

Hours after McCarron said he would "not be silenced" over the grooves controversy, the PGA Tour's situation became a little more muddled with Solheim's gentle reminder.

Mickelson was among at least four players at last week's tournament at Torrey Pines who used the Ping wedges, which have square grooves.
