Jordan Spieth has the lowest ever 36-hole score in relation to par in major championship history, has tied the all-time major championship 36-hole scoring record and has the lowest 36 hole mark in Masters' history.

The 21-year-old American continued to provide a golfing master class in the second round at Augusta National on Saturday (NZT), backing up his opening-round eight-under 64 with a bogey-free 66, leaving him at 14-under 130.

No player in major championship history has been 14 under or better at the halfway stage of play and the 130 ties the low score in major history.

It is the first time a player has posted 130 at Augusta National through the opening two rounds, beating Raymond Floyd's 131 from 1976.

While Spieth continued to surge, Australian Jason Day put his charge in reverse and will now need something extra special if he is to get anywhere near the coveted green jacket.

Day, who started the day just three off the pace, has dropped a distant 11 shots back thanks to playing his opening 16 holes two-over par, leaving him three-under and tied seventh.

American Charley Hoffman is the only player currently putting any sort of heat on Spieth, sitting at 10-under through 16 holes.

Ernie Els (72) and Paul Casey (six holes) are third, already nine shots back.

Day opened his round with a three-putt bogey on the first but he seemingly wiped out the problem by hitting a stunning approach to five feet on the par-five second before coaxing in the eagle putt.

He held firm for three holes with pars, the last an impressive save from a tough bunker lie, but then three-putted the sixth green for another bogey just as Spieth pushed forward with birdies.

Leaving his approach on the seventh short, despite a great drive, compounded his misery and the 27-year-old failed to get up and down from the sand to drop another shot.

There were bogeys at 11 and 14 before a birdie on the 15th stopped the rot.

Spieth notched birdies on the second, fifth, eighth, 10th, 13th and 15th holes and had a six-foot look on the 18th that, had it gone in, would have given him the major championship records all on his own.

Meanwhile, Tiger Woods produced his best golf of the year, firing a three-under-par 69 in the second round of the Masters to finish at two under.
