Well of course we all want Grigor to win today
After all if he does - he will reach his first semifinal at ATP 500 event, he will finally break the Top 50 and he will meet Roger.
The only bad thing is that he will have to skip the Paris Masters, because he has to start from qualies, but if he wins today - on Saturday he will play Roger. There's one SE spot in the Masters, but I think he need to play a final in Basel to get it and I don't think he will get a WC as well
So most probably a win today, means he will finish the season tomorrow with the match against Roger ... unless he beat him
the only other candidates for a SE were goffin, paire, mathieu and dodig.
goffin lost, paire will hopefully lose as well as mathieu
and dodig might also play a challenger (he could lose, too, of course). So if he wins he will be the only candidate for a SE
