Caddie and coach thanked for Clarke's flying start

Darren Clarke has had no difficulty finding somebody to thank after his brilliant opening 65 in the United States PGA Championship.

The Ulsterman, one ahead of Ernie Els and Justin Leonard entering today’s second round, praised both Yorkshireman Billy Foster and American Stan Utley for the part they had played – and he hopes will continue to play as he seeks his first major title.
