Day four at the ATP Halle brings some intriguing matchups on the grass. Players have had time to settle into the surface after the opening round and will now be looking to build their momentum ahead of Wimbledon. As always, we here at LWOT will be offering our predictions for every match on the slate in western Germany, but who will book a spot in the semifinals?
ATP Halle Day 4 Predictions
Fabian Marozsan vs Taylor Fritz
Head-to-head: Fritz 2-0 Marozsan
Fabian Marozsan showed some fight by coming through a three-set battle against Kecmanovic to reach this stage. The Hungarian has had solid moments this season, including a few notable wins earlier in the year, but grass has never been his strongest surface. He tends to rely on consistency from the baseline, yet the low bounce and faster pace can disrupt his rhythm.
Taylor Fritz, on the other hand, arrives with plenty of recent grass success. He had a good run in Stuttgart just before this event, showing he can handle the demands of the surface with his big serve and improving return game. His ability to open up the court and dictate play should give him the edge in longer rallies here. Marozsan can make it competitive if he finds his timing early, but Fritz looks better equipped overall.
Prediction: Fritz in 2
Ben Shelton vs Ethan Quinn
Head-to-head: Shelton 1-0 Quinn
Both Americans know each other well from their time coming up, but this feels like a step up in challenge for Ethan Quinn. The younger player has shown promise with some Challenger success and occasional upsets, putting together competitive sets against higher-ranked opponents. However, his consistency on grass is still developing, and he hasn’t faced this level of power regularly at this stage.
Ben Shelton comes in riding high after claiming the ATP Stuttgart title on grass last week, beating strong competition along the way. His lefty serve is a massive weapon on this surface, generating awkward angles and aces, while his athleticism helps him cover the court effectively. He has looked sharp transitioning from other surfaces and seems to enjoy the faster conditions. Quinn will need to serve exceptionally well to stay in it, but Shelton’s recent momentum and grass comfort should carry him through.
Prediction: Shelton in 2
Raphael Collignon vs Mattia Bellucci
Head-to-head: Bellucci 1-0 Collignon
Mattia Bellucci has been one of the stories so far at the ATP Halle Open, coming through qualifying and then pulling off a strong win over a defending champion in straight sets. The Italian lefty has found real rhythm on grass lately, using his forehand effectively and showing good court coverage. His confidence is clearly up after recent results.
Raphael Collignon has also been impressive so far at ATP Halle, navigating through to the second round after starting in the qualifying with solid baseline play and the ability to step up in big moments. The Belgian brings a well-rounded game that works on multiple surfaces, and he has looked comfortable enough adapting to the grass. This should be a close one with both players striking the ball cleanly. Bellucci’s current hot streak and grass form give him a slight nod in what could be a tight battle.
Prediction: Bellucci in 3
Alexander Zverev vs Yannick Hanfmann
Head-to-head: Zverev 1-0 Hanfmann
Yannick Hanfmann, not quite a local but still a home hope at ATP Halle Open, showed some good in advancing through his first match against Joao Fonseca, a player still finding his feet on the grass. As a German player, Hanfmann knows these conditions and can feed off the home crowd. He has played well in patches this season, particularly when he can dictate with his serve and enjoy time on the ball, but grass remains a tougher ask against top opposition.
Zverev has looked steady in his opener and brings strong pedigree on grass from past performances at this event and Wimbledon. His height helps with serving, and his groundstrokes allow him to control points from the back. He moves well enough on the surface and has the experience to close out matches when it matters. Hanfmann can push him with aggressive play, but Zverev’s overall level should prove too much.
Prediction: Zverev in 2
