Tiger Woods has admitted that there is still plenty of work to do if he is to add to his 14 major titles.
The former world number one was rated as the favourite by many to regain the Masters in Augusta over the weekend.
However, the 36-year-old was never in contention has he ended the four-day event on five over par.
"If I look back on the week, I played the par-fives atrociously," said Woods. "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."
Woods last won a major title in 2008.
