I agree they could all be interesting. 6 of 8 of those players are all in the top 15, on live rankings. (Dimitrov #26 and ADF #44.) Everyone has a lot to play for, in various ways.
Davidovich Fokina has been the revelation for me. I hadn't seen a lot of him prior. Fritz is following up his IW win, and first US player to get this far at MC in some 15 years. Hurkacz always dangerous. I have given up on Dimitrov, but he should know what a chance he's got in the top half.
In the bottom half, if Zverev and Tsitsipas keep to recent form and performance in the face of opportunity, they should both lose tomorrow.
In any case, I'll be routing for Sinner. He'll have the Italian support there, right on the border. And you can never bet completely against the Short Man.
