Thursday's Tokyo round of 32 pits Stefanos Tsitsipas against Tomas Martin Etcheverry on hard. Stefanos Tsitsipas has won 7 of the last 10. Tomas Martin Etcheverry is searching for form, having lost 2 in a row (4 of the last 10).

The serve is where this match separates: Tsitsipas has been winning 74.8% of first-serve points to Etcheverry's 71.2%, and on hard that gap compounds fast. A tiebreak or two would surprise nobody, with Tsitsipas fractionally more likely to land the big points.
