Two servers who almost never lose serve indoors, meeting on a fast court for the seventh time in eighteen months. The market prices a straight-sets match as more likely than the history of these two on hard courts suggests.
Why over 22.5 games
Three of their last four hard-court meetings went to a deciding set, and the fourth was 7–6, 6–4 — twenty-three games on its own. Both hold serve above 88% indoors this season and neither has been broken more than twice in any match this month, which makes tie-breaks the likeliest way a set is decided. Two tie-break sets are twenty-six games; a straight-sets win with one break in each is twenty-one. The line sits almost exactly between, and the recent history leans to the longer match.

Where it could go wrong
Last November’s meeting in this arena was 6–3, 6–4 — nineteen games — and Sandrelli indoors is capable of exactly that. A round-robin match is also one in which a player already qualified can go through the motions, and the schedule may make that true for one of them by Monday. A retirement voids the bet at most operators; check the rule at the one you use.
