Dustin Johnson takes control of Masters with third round 65

• World No 1 leads by four going into final day
• Ancer, Im and Smith share second place

Dustin Johnson continues to give the impression he feels Augusta National owes him one. By the close of the third round at this, the 84th Masters, the world No 1 had approached territory whereby the impact of failing to convert victory might be more interesting than such a scenario transpiring. Johnson - unflappable and, on this form, unbeatable - leads by four at 16 under par after a third round of 65. Johnson has the 72-hole Masters scoring record of 270, or 18 under, firmly in view.
