Turin (Italy), Nov 15 (AP) Alexander Zverev is into the semi-finals. Carlos Alcaraz, meanwhile, needs to wait to see if he will reach the last four at the ATP Finals.
Zverev beat Alcaraz 7-6 (5), 6-4 on Friday at the season-ending event for the year's top eight players.
Zverev won the group, finishing perfect with three victories. Alcaraz and Casper Ruud have a win each and Andrey Rublev has none.
Alcaraz needs Rublev to beat Ruud in the final group match later. Top-ranked Jannik Sinner won the other group ahead of Taylor Fritz.
So, Zverev will face Fritz in one semi-final and Sinner will likely face Ruud or Alcaraz in the other.
Alcaraz again wore a pink nose strip after coming to Turin sick and having struggled with breathing issues in his opening loss to Ruud.
Zverev leapfrogged Alcaraz to No. 2 in the rankings this week and now leads their career meetings 6-5.
It was a measure of revenge for Zverev, who was beaten by Alcaraz in five sets in this year's French Open final. (AP) AYG
