I think he'll have chances in all 4 slams next year. His results this year were 4R, SF, F (tied

), QF. There was no blowout, even in his loss to Nadl at RG19.
Yes, luck was mean to Fedr, and Djokodal won 2 each, but except for the AO19 win, the other 3 wins were not that convincing; Nadl lost a set to a schedule-screwed Thiem, Djokr lucked out against Fedr, and Nadl was on his last legs against Medv while essentially cheating in the 5th (he got away with it).
Remember, Fedr was essentially 1 pt away from being the best player of the year heading into USO19, and if he won that point, who knows how USO19 plays out?
I think Fedr will end 2019 in great form, with a title or 2. Like I've said before, I'm more confident in Fedr's form heading into 2020 than I was for 2019.
That, my friend, is a GOOD thing!
