Both players' recent matches and the expected straight-sets outcome make a tiebreak unlikely.
- H2H: No tiebreak in their only match.
- Rehberg's tiebreak avoidance: Only 2 of his last 15 matches featured a tiebreak.
- Donski's tiebreak rate: 3 of his last 15 matches had a tiebreak, but his fatigue reduces the chance of tight sets.

Donski's erratic second serve, especially under fatigue, makes over 5.5 double faults likely, as seen in their H2H.
- Donski's double faults: Averages 3.9 per match on clay in last 8, but 7.3 overall in last 15 (higher on hard courts).
- H2H: Donski had 7 double faults in their previous match.
- Rehberg's low rate: Only 1.5 double faults per match on clay, but Donski's high count alone can push the total over.

The read
Donski's serving style generates aces even on clay, and with Rehberg contributing a few, the total should exceed 5.5.
- Donski's ace rate: Averages 7.1 aces per match on clay in last 8 matches.
- Rehberg's ace rate: Averages only 2.6 aces per match on clay in last 15, but Donski's high count pushes the total.
