If Roger wins Montreal, he goes ahead of Rafa in the race rankings. Then Roger has to be the favourite to end no. 1 in the rankings. But, he will need to keep the aggression going. Less slices, more flat backhands, more net approaches.
Zverev seems to have become a regular contender in the ATP masters series.
Shapovalov seems to have gotten a kind of a breakthrough. One step ahead. I didn't know him well even seven days ago. Semis of a masters is a huge result. He should just begin playing on the main ATP tour right away. I don't think there is any reason not to do it. At least, he should start prioritising the ATP main tournaments.
Good for Haase, although I think it will end now. Time for Roger to deliver a masterclass. But is Haase defensive? I don't remember but I don't think.
P.S.: I am going by what one of you mentioned. Shapovalov is going to be around no. 75 after this tourney at the very least. A world no. 75 shouldn't have to play qualifiers in ATP 250s and ATP 500s. If he does score points there, in some time he won't need to play qualifiers in masters (I think he can get a main draw entry already at IW, Miami. But he will need to maintain his rankings till March, April next year)
