Switzerland are up against Argentina in the last eight of the United Cup. Playing in this tournament for the final time, Stan Wawrinka takes on Sebastian Baez. Read our match prediction below.

The winner of this tie will face either Belgium or the Czech Republic in the last four. Neither Switzerland or Argentina have ever got past this stage.

40-year-old Wawrinka will retire at the end of this year. He still has plenty of stamina because his two group games saw 74 games played and he was on court for just over six hours. The Swiss player lost to Flavio Cobolli but defeated Arthur Rinderknech. Those matches saw four tie-breaks played and one 7-5 set.

Wawrinka is up to 138th in the live rankings after those two victories. He won seven of his 11 outdoor hard court matches last year.

Sebastian Baez has been one of the surprises of the group stage. He only won three outdoor hard court matches last year but is already just one short of that total in 2026. Baez beat Jaume Munar in straight sets and then defeated world number nine Taylor Fritz in three sets.

We tip more than 9.5 games to be played in the first set of this match.
