Tiger Woods admitted he has a lot of work to do ahead of the US Open if he is to add to his 14 major titles.
The American never got into contention at Augusta and a closing 74 saw him finish on five over par.
So much of Woods' success in winning four Masters titles has been built on playing the par fives well and he admitted that he let himself down on the long holes this week.
"If I look back on the week, I played the par-fives atrociously," said Woods after mixing five bogeys with three birdies during his fourth round.
"This is a golf course you just have to dominate the par-fives, and I did not do that at all this week.
"I didn't drive very good and didn't hit my irons very good. I've got to go and do some work and be ready for the next one.
"What's frustrating is I know what to do, and I just don't do it.
"I fall back into the same old patterns again and I just need to do more reps. Thank God my short game was good this week and my putting was really good. Unfortunately they were all for pars, not for birdies."
