The Argentine, after losing in his debut in Cincinnati, has accumulated four defeats in the five matches following his success at Queen's.
Since the Masters 1000 in Canada, there have been hardly any major changes in the rankings, but the Spaniard and the American benefit from their good performance in Montreal.
The Polish player won her first WTA 1000 in Canada in Toronto after defeating Rybakina, ending an eleven-month trophy drought: "It has been the best week of the season."
The American successfully defended his title at the Canadian Masters 1000 and claims that “tennis is a sport where you have to keep improving or you'll be left behind.”
The Australian arrives in Ohio intending to turn around his inconsistent game shown throughout the year: "It only takes a good week to be back on top."
