Fritz, Shelton, De Minaur and Musetti are holding steady at No. 5 to No. 8 in the race, but a lot of points are on offer this week.

Also, Alejandro Davidovich Fokina and Linda Noskova make their Top 15 debuts, and American Ann Li cracks the Top 40.

At the tournament's new home, Carlos Alcaraz and Jannik Sinner are in the same draw for the first time since the US Open, while Felix Auger-Aliassime and Casper Ruud make 11th-hour bids for Turin.
