As Alexander Zverev said on Instagram, "not your everyday tennis rally." The No. 2 seed in Acapulco posted a routine 6-3, 6-3 win over qualifier Alexei Popyrin, complete with an unusual point.

After subduing the rising teenager, Zverev will face a challenge in veteran David Ferrer on Wednesday night for a spot in the quarterfinals.

The 21-year-old is also in the doubles draw, with his brother Mischa.
