Key takeaway

Fils's advantage on both serve and return makes him the stronger pick. Struff's route is to protect serve and keep sets close enough that Fils has little room to waste his return chances.

Arthur Fils's hard-court advantage on serve and return makes him the pick against Jan Lennard Struff in the BNP Paribas Fortis European Open semifinal. Court Shark's model gives Fils a 72% chance, though Struff's serve leaves a credible route to an upset.

## A return advantage with a final place available

A 24% break rate in his hard-court record gives [Arthur Fils](https://courtshark.ai/players/arthur-fils-209950) the clearest advantage against [Jan Lennard Struff](https://courtshark.ai/players/jan-lennard-struff-105526). His advantage extends to holding serve, giving him more than one way to control the score. That matters against an opponent whose service record suggests breaks could be scarce. It doesn't settle the match.

The semifinal in Brussels puts a place in the BNP Paribas Fortis European Open final within reach for players with different histories at this tournament. Fils had played one previous main-draw campaign, while Struff had appeared in five. Neither had won the title. The immediate question is whether Fils can turn his stronger return record into enough chances to separate them, rather than let sets narrow to a few points.

### Return games won: where they stand

Each dot is one of the ATP top 100 with enough matches in the last 52 weeks. Arthur Fils is 22nd of 94; Jan Lennard Struff is 72nd of 94.

## Fils leads on both sides of serve

Over the past year on hard courts, Fils's service and return figures both exceeded Struff's, making his advantage relevant to both sides of the matchup. The samples covered 37 matches for Fils and 33 for Struff. Those are substantial stretches of play, although they do not describe identical opposition or conditions.

Fils held 86% of his service games, compared with 83% for Struff. Both protected serve well. The distinction is that Fils combined that protection with a better chance of making progress when receiving, rather than relying as heavily on his own service games.

Struff broke in 19% of return games, below the tour's hard-court average of 23%. That suggests the more difficult task belongs to him: holding often enough to stay close while finding opportunities against the stronger service record. Fils has the clearer route to a break; Struff has the serve to make him wait.

## Struff can make the margins smaller

Struff's strongest route is to protect serve and force Fils to decide sets without a comfortable cushion. His Brussels results support that possibility: he beat Marcos Giron in consecutive tiebreaks and also needed a tiebreak against Zizou Bergs. Those results don't establish superiority in tight sets, but they show that his run here has already included the kind of scoring Struff needs.

The direct history is thin. Fils won their only previous meeting at the Paris Masters in 2024, so there is no repeated matchup pattern to confirm that his broader return advantage carries over against Struff. A single result cannot answer that question on its own.

Recent hard-court results also leave room for resistance: Fils won seven of his last 10, while Struff won six. If Struff keeps the semifinal close on serve, Fils's better return record may produce opportunities without producing an early separation.

## The prediction

Court Shark's model favors Fils with a 72% win probability, while the market consensus has him at 81%. The direction is clear. The disagreement is about how strongly to favor him, not which player has the better chance of reaching the final.

Court Shark's AI analyst also picks Fils, agreeing with the model's choice. His advantage in both holding and breaking provides the tennis case for that selection, rather than requiring a forecast built around Struff's serve failing. The model's median match length is 22 games, with a straight-sets Fils win the likeliest individual result.

The middle half of forecast outcomes runs from 19 to 29 games, leaving room for a longer contest even with Fils favored. His edge is persuasive, not decisive before play. The key test is whether his return advantage creates breaks before Struff can take another set into a tiebreak.

AI analyst

Picks Arthur Fils (agrees with the model)

Its case: Arthur Fils has the cleaner hard-court case: he won their only meeting 6-3 6-4, is 7-3 in his last 10 on hard courts versus Jan-Lennard Struff's 6-4, and owns a 65% longer-run hard-court win rate against 46%.

The risk it names: The risk is Struff's big serve on these quick indoor courts, 11.8% aces and 75.6% first-serve points won, and he arrives on a 3-match streak, though his 266 minutes over the past 7 days is much heavier than Fils's 104.

## Methodology and sources

How we build model estimates and where our information comes from.

Model estimates and observed results

The win probabilities come from the Court Shark match model, trained on completed ATP and WTA matches. A probability says how often a player in this position wins, not that one result will happen. The model's number for a match is recorded before play and never changed afterwards, so it can be checked against the result.

Sources and citations

Results, scores, rankings and serve statistics come from the Court Shark match database. The market consensus is the pre-match price for each player converted to a probability. Figures in this article are a snapshot taken when it was written.

Limitations

Serve and return rates count only matches with full serve statistics, which are sparser for Challenger and lower-level events, and the tour average they are compared with covers every year on record. Head-to-head records count every meeting with a recorded winner, walkovers and retirements included. Charts and tables are a snapshot and do not update after publication.
