Alexander Zverev suffered a straight-sets defeat in his first match since ascending to the world No. 1 ranking, falling to Italy's Lorenzo Musetti on November 4, 2026. The German, who recently claimed the top spot in the ATP rankings, was upset by Musetti in what marked a disappointing start to his tenure as the world's top-ranked player.
Reuters reported that Musetti produced a commanding performance to dismiss the new world No. 1 in straight sets. The result represents a significant early test for Zverev, who had worked for years to reach the summit of men's tennis.
