Day three of the Masters begins with 54 golfers scratching their heads as to how they can catch runaway leader Jordan Spieth.

The 21-year-old American leads by an incredible five shots heading into the third round after following up his opening 64 with a second round 66, and he'll be partnered by his compatriot Charley Hoffman who begins his round on 9-under-par.

Two Englishmen are also in the mix with both Justin Rose and Paul Casey joined by Dustin Johnson on 7-under, while three-time Masters champion Phil Mickelson sits a shot further behind on 6-under.
