Phil Mickelson set a daunting clubhouse target of three under par on the final day of The Open Championship at Muirfield.

Five behind Lee Westwood at the start of the day, the left-hander took just 66 shots in his fourth round to surge through the field.

With holes running out Westwood was three behind on level par, Adam Scott and Henrik Stenson a shot further back on the course and Ian Poulter one over in the clubhouse.
