I think Stan's run of success might be catching up with him. He's played really well lately, but that also means he's been playing more than usual, so I wouldn't be surprised if he hits a wall. Same for Dimitrov, but I think he might get through Stan first.
It's all very exciting wondering about the various match-ups that could happen in the coming days. Hopefully Andy will be in the mix, but it is nice that it's not just him being unpredictable. Or perhaps he can be unpredictable by having a really good run here!
