The two-time champion went undefeated in round-robin play and put Alcaraz on the brink of elimination in Turin on Friday.

He beat all of his Big Four rivals in the season-ending championship, and twice reached the final.

It’s the most in either ATP or WTA rankings history.

The Aussie will be unranked at the 2025 opening week stop, having played just one match since the start of 2023.

Alcaraz has beaten Zverev twice in a row, but the German has been the better player in faster conditions.

Viktoria Hruncakova and Tereza Mihalikova completed the surprise victory, surviving a late rally by Taylor Townsend and Ashlyn Krueger.

The ATP fines committee handed Tiafoe a penalty of $60,000 for aggravated behavior on top of the maximum on-site fine of $60,000 he got for verbal abuse.

The country's 2010 World Cup hero “felt like a tennis player for a moment,” after competing in his first professional event alongside Federico Coria.

Sinner will be joined in the last four by Taylor Fritz, who rallied from a set down to defeat Alex de Minaur earlier on Thursday.

The 22-time major winner posed for pics and enjoyed his first practice in the host city Thursday.

And if Sinner wins just one set against Daniil Medvedev tonight, Fritz qualifies for the semifinals too.
