Alexander Zverev reached the third round at the Madrid Open with a three-set victory over Mariano Navone.

The second seed won 6-1 3-6 6-3 in an hour and 44 minutes and will face Terence Atmane in the next round of the competition.

The first set was straightforward for Zverev, who converted two of his three break-point opportunities to take the lead.

However, Navone found his rhythm in the second and broke Zverev's twice on his way to a 5-1 lead, though the Argentinian dropped one service before taking the set.

Zverev was back to his best in the third, with one break of serve enough for the German to clinch victory, which he did with his second match point.
