Alexander Zverev He missed the quarter-finals of the ATP Monte Carlo Masters despite making up ground and suffered a setback at the start of the clay court season. The Olympic champion from Hamburg lost on Thursday in his adopted hometown to feared rival Stefanos Tsitsipas after a disappointing performance 5: 7, 6: 7 and is still waiting for his first singles title this season.

At the same time, Zverev's already negative record against Tsitsipas worsened. The 26-year-old's five wins against the two-time Grand Slam finalist are now compared to ten losses. Zverev's hope of quickly finding his best form after changing the surface from hard court to clay has yet to be fulfilled.

Zverev, who had confidently beaten Austrian Sebastian Ofner in his first appearance in the Principality, lost control of the match after a concentrated start and four lost break points. Tsitsipas then quickly pulled away in the second set against the increasingly frustrated fifth in the world rankings.

Zverev again defended impressively, equalizing after being 5-0 down and forcing a tiebreaker against the Greek, but finally enjoyed the crowd's applause after converting the third match point. The last German professional remaining in the competition is Jan-Lennard Struff, who will face Melbourne winner Jannik Sinner on Thursday.
