Fernando Verdasco advances to the fourth round of the Miami Open after registering a victory over fellow Spaniard Rafael Nadal 6-4, 2-6, 6-3 on Sunday. Nadal has defeated Verdasco first 13 times they played in a row but now lost to him twice in a row. Nadal has never won the tournament in 11 appearances. It is the only event he has never won in so many attempts. He’s the only member of the vaunted Big Four who never won on Key Biscayne. Verdasco broke nadal twice in the first set and clinched the set due to a forehand error from Nadal in 43 minutes. Nadal came back in the second set after breaking Verdasco twice to win the set in 45 minutes. But the former Australian Open semifinalist earned a crucial break in the third and went on to win the match in two hours and 15 minutes. Nadal converted only three of 12 break-point chances and committed 40 unforced errors, with just 18 winners. Nadal dealt with several health issues in 2014 and said that while he’s fully recovered, he hasn’t regained his confidence. “It’s a question of being relaxed enough to play well,” the 14-time Grand Slam champion said. “I’m still playing with too much nerves for a lot of moments, in important moments, still playing a little bit anxious in those moments”. “But I’m going to fix it — I don’t know if in one week, in six months, or in one year, but I’m going to do it.” With the clay court part of the season coming up, Nadal's preferred surface, he said the opportunity is there for him to turn his form around but he said that would not happen if he is unable to fix his mental issues.
