Key Prediction Insights

This round-of-16 match in Rotterdam (Netherlands) on indoor hard courts at an ATP 500-level event pits Jan-Lennard Struff against Alexander Bublik. The model strongly favors Bublik — predicted winner Alexander Bublik (79.79%) over Jan-Lennard Struff (20.21%) with an expected total of about 23.5 games in the match.

Match Analysis

Bublik enters this tie with clear statistical advantages: a top-10 ranking versus Struff’s 84, an Elo rating of 2972.6 compared with 655.5 for Struff, and a much higher form index (78.15 vs 38.46). Surface strength indices also favor Bublik (19.84 vs 5.71). Fatigue data show Bublik has accumulated 142 minutes in the event so far versus Struff’s 64 minutes, which is a factor to monitor given match length projections. Serve and return metrics point to a decisive edge for Bublik. His mean serve index (97.98) exceeds Struff’s (67.07) by over 30 points, and his mean return index (87.70) is roughly 38 points higher — both differences well beyond the 5-point threshold and likely to shape the contest. Recent form: Struff has 1 win and 2 losses in his last three matches (including a 64-minute Rotterdam win), while Bublik has two wins and one loss over his last three, including a 142-minute Rotterdam victory. Those recent results reflect Bublik’s stronger overall trajectory coming into this round.

Aces and Double Faults Predictions

The aces prediction for the match is about 16.86 total, with an expected double faults total near 5.74. On a medium-paced hard court, predicted aces should be moderate — harder than clay but typically fewer than grass — and Bublik’s far superior serve rating suggests he will contribute a large share of the predicted aces. The double faults prediction reflects some risk from aggressive serving combined with the match’s expected short length.
