Great start sends Casey clear

Paul Casey went from one ahead to four clear with a sparkling start to the final round of the Johnnie Walker Championship at Gleneagles today.

The 28-year-old Englishman birdied the opening three holes while Colin Montgomerie, who had been four clear at one point yesterday, bogeyed the first, birdied the par-five second and then had to make a 12-foot par putt on the next just to stay second on his own.
