I’ll take either of Thiem or Med, really. Zverev feels deserving too since he’s had such success below the slam level (and has now had two good back-to-back slam runs).
Shapo and Rublev are both fun to watch and are still young and developing so I suppose a win here would bode well for their future success, but it also feels like it could be a one-off given how inconsistent they both can be (especially Dennis the Menace).
PCB would be fun for the lulz and he seems like a nice guy, so as ridiculous as it would be, I wouldn’t hate seeing him as champion. Boric and De Minaur need to stay the hell away from that trophy.
