Rory McIlroy is aiming to become only the fourth man to win the Masters back-to-back

The drama which Rory McIlroy has produced at the Masters over the years - the type that left his fans peeking through their fingers - is woven into the fabric of his story.

When McIlroy moved into a record six-shot lead at the halfway point, it felt like this year's tournament was going to see a different chapter written, one about a rather sedate affair which demonstrated control rather than chaos.

Many predicted a procession for the defending champion going into Saturday's third round. They should have known better.

Northern Ireland's McIlroy saw his commanding lead evaporate in a dramatic day where he swung the door wide open to his rivals with a one-over par 73.
