Young gun American Jordan Spieth continues to hold court early in the final round of the Masters as he looks to become the second youngest champion at Augusta National.

Spieth is one under through six holes of the final round to maintain his overnight four-shot advantage over former US Open champion Justin Rose, who now sits at 13 under.

Spieth has taken his tournament birdie tally to 24, just one short of the all time record of 25, with gained shots on the first and third holes.

A bogey on the fifth is his only early blemish as he seeks to be only the fifth wire-to-wire winner in Masters history, joining Craig Wood in 1941, Arnold Palmer in 1960, Jack Nicklaus in 1972 and Raymond Floyd in 1976. He would also be the second youngest behind Tiger Woods from 1997.

Phil Mickelson is even for the round through seven holes to now be six back at 11 under, the last of the realistic challengers.

Australia’s tilt has been obliterated with Jason Day the best of the bunch in a tie for 32nd, currently four over on his round through 11 holes to be even par for the tournament, a whopping 17 shots back.

John Senden closed with a 72 to be one over while 2013 champion Adam Scott is having a round to forget, three over through 17 after a quadruple bogey seven on the picturesque par-three 12th.

Scott is two over for the tournament and Geoff Ogilvy closed with a 74 to be three over.

World No.1 Rory McIlroy is eight under par through eight holes to be tied fifth and 14-time major winner Woods is four under for the week through eight after two early bogeys on Sunday.
