The read

Slightly elevated double-fault rates on grass, combined with both players' moderate DF tendencies, make over 5.5 a marginal but plausible outcome.

• Iatcenko's double-fault rate is 4.4% (career 747 DFs in 292 matches, ~2.6 per match); Bai's is 3.2% (440 DFs in 215 matches, ~2.0 per match).
• In their H2H, they combined for 3 double faults in 17 games, but that was on hard court; grass can lead to more errors on second serves.
