Dustin Johnson admits his planned retirement is already on his mind, but the new Masters champion wants much more major glory before it arrives.

Johnson recovered from a somewhat shaky start in the final round to cruise to a record-breaking five-shot victory at Augusta National, his winning total of 20 under par eclipsing the previous tournament record of 18 under set by Tiger Woods in 1997 and equalled by Jordan Spieth in 2015.
