Nadal goes the distance to beat German teenager Zverev

Rafael Nadal has overcome a spirited challenge from 19-year-old Alexander Zverev, beating the German teenager 4-6, 6-3, 6-7 (5), 6-3, 6-2 to advance to the fourth round of the Australian Open.

Nadal broke Zverev's serve in the opening game of the final set, lost his own serve, and then broke back in the fifth game to advance to a Round of 16 match against Gael Monfils.

The match started ominously for Nadal when he lost his serve in the opening game. Zverev hit a deft drop shot while stretched out completely on break point.

But Nadal, who had two lengthy injury spells last year, settled into the match and dominated after losing the third-set tiebreaker. At the end of the 4 hour, 6-minute match, Nadal pumped both arms toward the court in celebration.

Zverev was attempting to join his older brother Mischa, who plays Andy Murray on Sunday, in the fourth round.
