Jannik Sinner and Alexander Zverev have both qualified for the semifinals of the first four Masters 1000 tournaments of the 2026 season, according to r/tennis. The achievement places them in rare company: only Roger Federer in 2006 and Rafael Nadal in 2010 and 2011 have previously reached the semifinals of the opening four Masters events in a single year.
The consistency required to advance this far in four consecutive Masters 1000 tournaments underscores the depth of form both players have demonstrated early in the season. Federer, Nadal, and now Sinner and Zverev represent the only four instances of this accomplishment in ATP history, highlighting how difficult it is to maintain peak performance across multiple elite-level events in rapid succession.
For North American viewers tracking the ATP calendar, this early-season run by both players signals the competitive intensity building toward the summer hard-court swing and beyond.
