Nuno Borges, who still hasn’t lost a single “set” in Phoenix, will now face the Australian Alexei Popyrin, 101st ATP.

The Arizona Challenger has a very strong field of players, taking into account the category of the tournament, due to the fit between the two Masters 1000 – Indian Wells and Miami – which take place in March in the USA.

Matteo Berrettini, Gael Monfils, Richard Gasquet, Emil Ruusuvuori, Jiri Lehecka, Mikael Ymer and Alexander Bublik are some of the big names to compete in the tournament, until Sunday.
