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.

Fonseca took his lumps in his rookie season, and bounced back with his biggest title in Basel, while Sinner found his top level at 5-5 in the third against Zverev.

The German has now qualified for the elite event in eight of the last nine years. He's won it twice, in 2018 and 2021.
