For the second time in three majors, Darren Clarke holed-in-one in practice for the US PGA championship at Whistling Straits on Wednesday.

Clarke aced the 143-yard 12th - and as the ball was in the air his caddie Billy Foster, now back working with the Ulsterman, shouted: "No, no - not today." The aim is to do it in the the tournament itself and not in warm-up, of course.

Two months ago in the US Open at Shinnecock Hills Clarke holed-in-one on the short 11th and then when the event started he missed the halfway cut.
