History

The Libema Open, long also known as the Rosmalen Grass Court Championships, was first held in 1990 and has grown into one of the most charming stops on the ATP and WTA calendars. Played on the natural grass of Autotron Rosmalen since its inception, the event has always occupied a prime slot at the very start of the grass season, immediately after Roland Garros, giving players their first taste of the surface on the way to Wimbledon. Patrick Rafter and Nicolas Mahut share the record for most men's singles titles with three apiece, while Richard Krajicek holds the record for most match wins, with 25. The honour roll ranges from a 20-year-old Lleyton Hewitt in 2001 to home heroes Tim van Rijthoven in 2022 and Tallon Griekspoor in 2023. After the 2020 and 2021 editions were cancelled because of the COVID-19 pandemic, the tournament returned in 2022 and has since produced a run of breakthrough champions, including Canada's Gabriel Diallo, who captured his maiden ATP Tour title here in 2025. The 2026 edition, the 35th in tournament history, is led by tournament director Marcel Hunze.

Tournament Data

's-Hertogenbosch sits essentially at sea level (Rosmalen is roughly 5 metres, or about 16 feet, above sea level), in the flat, low-lying Dutch countryside. The natural grass courts at Autotron Rosmalen play as a classic, relatively quick grass surface, a dramatic change of pace and texture from the heavy European clay that immediately precedes them.

These are the characteristics to expect on grass, consistent year to year:

Significantly higher ace counts and more free points on serve than during the clay swing that came before, as the low, skidding bounce rewards big first serves and flat hitting
Much shorter average rallies, with points often decided in the first few strikes; first-strike tennis and serve-plus-one patterns dominate
A low and sometimes unpredictable bounce that places a premium on footwork, soft hands and feel at the net
Higher service-hold and tiebreak rates than on clay, which makes early-week grass results notoriously streaky and upset-prone while players are still adjusting from the dirt
Cool, damp June air at sea level tends to keep the Dutch grass on the slower, lower-bouncing side compared with the quicker, drier grass elsewhere on the swing

Tournament Past Winners

Year	Winner	Runner Up	Semi-finalist 1	Semi-finalist 2
2025	Gabriel Diallo	Zizou Bergs	Ugo Humbert	Reilly Opelka
2024	Alex de Minaur	Sebastian Korda	Tallon Griekspoor	Ugo Humbert
2023	Tallon Griekspoor	Jordan Thompson	Emil Ruusuvuori	Rinky Hijikata
2022	Tim van Rijthoven	Daniil Medvedev	Felix Auger-Aliassime	Adrian Mannarino
2019	Adrian Mannarino	Jordan Thompson	Borna Coric	Richard Gasquet

The 2020 and 2021 editions were not held because of the COVID-19 pandemic, so 2019 appears as the fifth most recent edition.

Weather

This week in 's-Hertogenbosch, conditions are classically cool and changeable for early summer in the Netherlands. Daytime highs hover between roughly 14 and 19°C (58 to 66°F), with cooler, damp mornings and evenings and high humidity. The opening days have been wet, with rain and scattered showers a recurring theme, before slightly drier but still unsettled conditions arrive toward the closing weekend, where the rain risk eases without ever fully disappearing. Rain interruptions are a realistic and recurring possibility in Rosmalen in June, and the heavy, moisture-laden air typically keeps the grass slower and lower-bouncing than it might otherwise play.

Key 2026 News and Storylines

Late Withdrawals and Absences

Arthur Fils, Cameron Norrie and Alexander Blockx have all WITHDRAWN. All three were originally entered and seeded, but Fils and Norrie are sidelined by injury, and the pull-outs reshaped the seedings just before the draw was made. None of them feature in 's-Hertogenbosch this year.
Ben Shelton, Taylor Fritz and Alexander Bublik are NOT in the field. The biggest grass-court names of the week chose the rival ATP 250 in Stuttgart, which runs the very same week, leaving 's-Hertogenbosch with its own distinct headline cast.
Alexander Zverev (new Roland Garros champion) is NOT playing this week at all. After winning his maiden Grand Slam in Paris, the German is resting and will not begin his grass season until the ATP 500 in Halle, so he features in neither 's-Hertogenbosch nor Stuttgart.
Carlos Alcaraz (Spain) is OUT, still sidelined by the wrist injury that forced him to withdraw from Roland Garros. He remains absent from the grass build-up.
Jannik Sinner (World No. 1) is NOT in the field. After a shock early exit in Paris, the Italian is taking a lighter route into Wimbledon and skips the grass 250s.
Novak Djokovic is NOT entered, continuing his pattern of minimal grass-court tune-up matches ahead of Wimbledon.

Key Players In (or Status to Watch)

Felix Auger-Aliassime (top seed, Canada) is IN and the headline name. Now up to World No. 4 after a run to the Roland Garros quarter-finals, the Canadian's big serve-and-forehand game is tailor-made for quick grass. He reached the semi-finals here in 2022 and arrives in fine form and confidence.
Alex de Minaur (second seed, Australia) is IN on a wildcard. The 2024 champion, who had to skip last year's edition through injury, is a proven grass-court performer who also won Eastbourne in 2021. His speed, return and relentless competitiveness make him a constant threat, though his recent form is a question after a lean clay swing.
Daniil Medvedev (Russia) is IN. The 2022 finalist (he lost that year's final to wildcard van Rijthoven) has quietly become a strong grass-courter, with multiple Wimbledon semi-finals and a Mallorca grass title to his name. On his day he is a clear title contender, even if he can run hot and cold.
Tallon Griekspoor (Netherlands) is IN and leads home hopes. The 2023 champion always lifts his level in front of the orange-clad Rosmalen crowd.
Gabriel Diallo (defending champion, Canada) is IN, back to defend the maiden ATP Tour title he won here in 2025 with a serve-led run to the trophy.
Arthur Rinderknech, Ugo Humbert, Zizou Bergs and Marin Cilic round out a dangerous field. Bergs was the 2025 runner-up, Humbert is a two-time recent semi-finalist, and veteran Cilic, the most decorated grass-courter in the draw, returns to 's-Hertogenbosch. Denis Shapovalov, Botic van de Zandschulp and Nuno Borges add further big-serving, grass-friendly firepower.

With the very top of the game in Stuttgart, injured or resting, the draw is genuinely wide open. Auger-Aliassime and De Minaur head the betting, but Medvedev's grass pedigree, Diallo's title defence, Griekspoor's home support and a cluster of big-serving floaters make this a classic, unpredictable grass-court 250.

Summary

The Libema Open offers the first proper taste of grass after a long clay season. The quick, low-bouncing turf at sea level rewards big serving, flat hitting and first-strike aggression, and it asks players to adapt fast from the patient grind of the dirt. Expect short rallies, plenty of holds, a healthy tiebreak count and the kind of early-week upsets that the surface change always produces.

So, expect serve-led, aggressive tennis to be at a premium, with shotmakers and players who move well on a slick surface holding the edge over pure baseline grinders. With the biggest names of the moment over in Stuttgart, sidelined or resting, Auger-Aliassime and De Minaur head a wide-open field, while Medvedev, Diallo, Griekspoor and a host of grass-friendly floaters can all make a run.

Ready for the grass-court season to begin at the picturesque Autotron Rosmalen, the first stop on the road to Wimbledon? With Auger-Aliassime fresh off a career-best clay Slam, De Minaur chasing a second title, Diallo defending his crown and a draw without a clear favourite, this could be one of the more narrative-rich Libema editions in years. Let's see who handles the transition to grass best and cashes in the fantasy points.

Did You Know?

A wildcard ranked No. 205 once won the whole thing. In 2022, Dutchman Tim van Rijthoven produced one of the great grass-court fairy tales, winning the title in essentially his first full ATP main-draw week. He beat World No. 2 Daniil Medvedev 6-4, 6-1 in the final and then carried that form all the way to the fourth round at Wimbledon.
Nicolas Mahut holds an unusual double record. He is tied with Patrick Rafter for the most singles titles, with three, and he is also both the oldest champion (34, in 2016) and the lowest-ranked champion in tournament history, having won the 2013 title ranked No. 240 in the world.
