Hamburg Open — Prize Money, History & Past Champions

Hamburg's Rothenbaum: the red-clay elder of the German spring

The Hamburg Open is one of the oldest events on the calendar — Germany's premier clay tournament, contested since the late 19th century and anchored for a full century at the Am Rothenbaum complex. Its identity has always been tied to its slot in the schedule. For decades it ran in May as a Roland-Garros tune-up, then spent the 2009-through-late-2010s stretch buried in July, before returning to the pre-slam window. In 2026 it sits May 17-23, the last meaningful 500-level red-clay stop before the draw at Roland-Garros locks in — the springboard role the event was built around.

What sets Hamburg apart from the clay-swing field is scale and surface. The center court is one of the largest dedicated tennis stadiums in Germany, with a retractable roof that keeps the slow, high-bouncing red clay in play through the region's unreliable May weather. It rewards the patient, heavy-topspin grinder rather than the flat-hitting shotmaker — the kind of court where rallies stretch and the serve matters less than on any hard-court 500 like Dubai or Rotterdam.

The recent honor roll skews young and continental. Alexander Zverev, the hometown favorite, lifted the 2023 title past Laslo Djere before Arthur Fils edged Zverev in a three-set 2024 final that turned on a deciding-set tiebreak. Flavio Cobolli broke through in 2025, taking out Andrey Rublev in straight sets for his signature clay result to that point.

The 2026 edition produced the surprise of the run: qualifier-tier outsider Ignacio Buse beat Tommy Paul over three sets — dropping the second 6-4 before closing 6-3 — to claim the trophy, the kind of unseeded breakthrough Hamburg's deep, attritional draws have a habit of producing.
