Indoor hard-court action continues at the ATP Rotterdam Open as we approach the business end of the week. With conditions rewarding first-strike tennis and sharp movement, each of these match-ups will be a test of form, experience, and adaptability. As always, we here at LWOT will be offering our predictions for every match on the schedule. But who will advance?

ATP Rotterdam Day 4 Predictions 
Botic van de Zandschulp vs Stefanos Tsitsipas

Head-to-head: Tsitsipas 2-0 van de Zandschulp 

Botic van de Zandschulp graced his appearance before a supportive home crowd with a straight-sets win in his opener here, showing good baseline consistency and fight on the indoor surface in front of the home crowd. Stefanos Tsitsipas has looked solid in his first match at the aTP Rotterdam Open, using his heavy groundstrokes and strong serving to control points quickly on these fast courts where he has a strong pedigree. Their previous meetings on indoor hard both went Tsitsipas’ way in straight sets, and his experience in these conditions should help him dictate the rallies more effectively.

Prediction: Tsitsipas in 2

Ugo Humbert vs Guy Den Ouden

Head-to-head: first meeting

Ugo Humbert comes into the ATP Rotterdam Open hot after upsetting a top seed in three tough sets, bringing sharp serving and aggressive baseline play that suits the quick indoor hard perfectly. Guy Den Ouden, as a local wild card, pulled off a solid straight-sets win to reach this stage, showing composure and clean hitting under pressure. This is their first clash, but Humbert’s higher-level experience and ability to handle big moments in recent indoor events give him the edge to pull away in the key games.

Prediction: Humbert in 2

Alex de Minaur vs Stan Wawrinka

Head-to-head: de Minaur 1-0 Wawrinka 

Alex de Minaur was efficient in his opener, winning in straight sets against the returning Arthur Fils, relying on his quick movement, precise returns, and defense-to-offense transitions that work well on indoor hard. Stan Wawrinka, as a wild card, delivered a solid win of his using his powerful one-handed backhand and flat shots to finish points early – albeit against an opponent yet to celebrate his 18th birthday. Their only prior meeting saw de Minaur come through, and his speed plus consistency in longer rallies should help him wear down the veteran here.

Prediction: de Minaur in 2
