ATP Den Bosch Day 2 Predictions Including Tallon Griekspoor vs Botic van de Zandschulp

Plenty of matches are on the schedule at the ATP Den Bosch event this week, with players hoping to fine tune their games on the quick grass courts. LWOT predicts each of the Tuesday first round matchups, with this set of predictions featuring the home-favorites Tallon Griekspoor and Botic van de Zandschulp of the Netherlands. Who will advance? 

ATP Den Bosch Day 2 Predictions

Jaume Munar vs Martin Damm 

Head-to-head: First meeting 

Munar nearly stunned the tennis world last grass court season, when he had a lead on World No. 1 Carlos Alcaraz at the HSBC Championships in London. This year, however, the Spaniard has put together a disappointing 8-11 record on tour, and his ranking has started to slip. On the other side of the net, Damm has an intriguing left-handed game, as the American is not afraid to use the net to his advantage. He won two matches in the qualifying draw, and his imposing height and aggression could give him the confidence to win in an upset. 

Prediction: Damm in 3 

Gabriel Diallo vs Adrian Mannarino 

Head-to-head: First meeting 

Mannarino won this tournament in 2019, which was notably the first ATP Tour title of his career. The 37-year-old is now ranked just inside the Top 50, though he finds himself on a tough nine-match losing streak. Unfortunately for the Frenchman, Diallo is quite powerful off his serve, and possesses the faster legs; however, he too has had a tough 2026. The Canadian has faced some mid-match retirements as of late, but he should be the slight favorite to get this match done on Tuesday. Mannarino will have to use his funky game and force Diallo into lots of unforced errors.
Prediction: Diallo in 3 

Otto Virtanen vs Kamil Majchrzak 

Head-to-head: First meeting 

This is the pair’s first meeting at tour level, but the two faced off just last week in a lungbusting triple-tiebreak epic at the Birmingham Challenger semifinals. Virtanen won 7-6(6) 6-7(5) 7-6(7) over the Pole, so this will be a prime opportunity for Majchrzak to clinch some revenge. Virtanen has more matches behind his belt, while both players like to use first-strike tennis and hit big first serves. This match feels like another toss-up, but Majchrzak should be better rested and could turn the tables here. 

Prediction: Majchrzak in 3

Tallon Griekspoor vs Botic van de Zandschulp

Head-to-head: Griekspoor 2-1 

Neither player has played particularly well in 2026, but on home soil, tough seasons can be put aside. Griekspoor has the better record at this tournament, as the 2023 champion and 2024 semifinalist–with nine matches won. Van de Zandschulp has had a slightly better season on tour, though his game is better oriented to clay courts and longer rallies. He’s also 0-3 at this tournament, falling in a final set in each of his defeats. Griekspoor has the slight edge in this compatriot rivalry, and his grass court experience may be the deciding factor.
Prediction: Griekspoor in 2
