Following his big win over Roger Federer in the first real test of his comeback to the ATP Tour, Rafael Nadal has earned a ticket to the finals.

The 26-year-old Spanish tennis star rallied to beat Tomas Berdych in the semi-finals of the BNP Paribas Open at Indian Wells and reach his fourth ATP Tour final in as many events. The final score: 6-4, 7-5.

Nadal, back in action after a knee injury which sidelined him for seven months, has got off to the best start of his career this year with 16 wins and only one defeat, with this latest victory being his 13th consecutive one.

Nadal, seeking his third consecutive Indian Wells title, now meets Argentina’s Juan Martin del Potro, who defeated Andy Murray in the quarterfinals and Novak Djokovic in the semifinals..

“It’s very, very difficult to imagine something like this,” said Nadal, who has won two clay-court titles this year and finished runner-up in another. “But here we are today, and very happy about all what happened the last month, especially last three weeks,” said Nadal.

“I don’t have nothing to lose after seven months,” Nadal added. “I did much more than what I dreamed. Victories like today, like the other day, helps you a lot for the confidence.”
