World number one Rafael Nadal booked his place in the semi-final of the Australian Open with a 3-6 7-6 (7-3) 7-6 (9-7) 6-2 win over Grigor Dimitrov.
The world ranked number 22 didn't give Nadal an easy ride after taking the first set. The Spaniard had to come from behind with a blistered racquet hand, that he later admitted affected his game.
He told BBC Sport: "With the serve, I feel the racquet goes, but it's fine. I will try and improve the hand tomorrow and then try to be ready for a tough match against Roger or Andy.
"It's not a problem in practice, the blister is much better but if I am not playing with protection, it can be much worse."
Nadal lead 4-2 in the third set but allowed the Bulgarian back into the match when he double faulted and gave Dimitrov three chances to take the set.
The match came down to two deciders but Nadal held his nerve to see out victory in three hours 37 minutes. After the game the Spaniard admitted how lucky he was.
"I was lucky, he missed an easy forehand and another one," he finished.
The 27-year-old will now face the winner of today's quarter-final between Andy Murray and Roger Federer.
