Two-time champion Jose Maria Olazabal said he was relieved to have "survived" the hardest playing conditions he has ever experienced at Augusta National.
Olazabal, the winner in 1994 and 1999, was 11 over for the weekend
The 41-year-old Spaniard, the last European to win the Masters when he triumphed in 1999, carded a 77 on Sunday for a 16-over total.
The Ryder Cup star said: "It was all about survival out there.
"It's been terrible in that regard this week - pars were good. This has been the toughest Masters I have played."
Olazabal, who also won in 1994, was playing in his 20th Masters but none of those saw scoring as high as this one.
The 54-hole lead of two over par was two shots higher than the previous highest lead at that stage of the tournament.
And champion Zach Johnson's score of one-over 289 was the joint highest winning total in Masters history.
