The 2012 Masters champion was three shots clear of playing partner Jordan Spieth after the two Americans emerged from Amen Corner, the treacherous run of three holes from the 11th, that often decide the green jacket.

The two opened the day sharing the lead at five under, but it was Spieth, a 20-year-old Texan seeking to become the youngest Masters winner, who initially looked the more comfortable oof the two.

He was two clear by the time they stepped off the third tee, with another American, Matt Kuchar, joining him on six under.

But a four-stroke swing in Watson's favor at the eighth and ninth put the 35-year-old former champion two clear before Spieth reduced that to the thinnest of margins at the 10th.

They both parred the 11th to start Amen Corner, but Spieth went in the water at the par-three 12th and the gap was back to two shots, with Swede Jonas Blixt moving up to equal second on five under.

Watson then took advantage of a tremendous tee shot on the par-five 13th to grab another birdie and move three clear of Spieth and Blixt with five to play.
