KEY BISCAYNE, Fla. -- No. 4 seed Roger Federer moved closer to his 'Sunshine Double' as he advanced to the quarterfinals of the Miami Open with a straight sets win over Roberto Bautista Agut on Tuesday. His compatriot Stan Wawrinka wasn't as fortunate after he was stunned by 19-year-old Alexander Zverev in the fourth round.
Bautista Agut held his own as he went toe-to-toe with Federer in the first set, both players holding serves, sending the set to a tiebreak where Federer pulled away to wrap up the set 7-6(5).
In the second set, Federer broke in the first game but the Spaniard broke back right away, leveling the set. Like the first set, Bautista Agut stayed closed to the Swiss, refusing to be broken again as they sent the set to another tiebreak where classic Federer pulled away gain to claim the match 7-6(5), 7-6(3).
Federer will next play Tomas Berdych, who had a tough three-set win against Adrian Mannarino in the fourth round. Federer and the Czech have played 23 times, with Federer leading 17-16 in their head-to-head. They last met in the third round of the Australian Open in January, where eventual winner Federer won in straight sets.
Federer hasn't lost a set in 9 matches and is aiming to notch the 'Sunshine Double' this weekend.
In the Wawrinka-Zverev match, the teenager came from a set down to triumph over the top seed. Wawrinka won the first set 6-4 but Zverev recovered in the second set and ran away with the third, losing only three games in the last two sets.
"I think the level was quite up and down," said a dejected Wawrinka." We were both fighting a little bit in the first set to find good level. Was really humid, not easy to play some great tennis, but we had some long rally.
"Yeah, one bad game to start the second set and then it was tough for me. I don't know. I completely went down physically and mentally, and also my tennis was completely out.
"I had no more gas," Wawrinka added.
Zverev awaits the winner of Nick Kyrgios and David Goffin. Should Kyrgios beat Goffin, Zverev will get a chance to avenge the BNP Paribas Open fourth round loss.
Not to get ahead of ourselves but's there's still a strong chance we might have a Federer-Nadal final this Sunday.
