Alexander Zverev reached the quarterfinals at the French Open in Paris. The tennis Olympic champion won against the Spanish qualifier Bernabe Zapata Miralles 7: 6 (13:11), 7: 5, 6: 3 on Sunday, but showed a poor performance overall. Zverev (25) will have to improve significantly if he actually wants to play for the title at Stade Roland Garros this year.
