Sheer GOATness up to 6-1 3-1, then Fed's level dropped and Krajinovic got back into the set but lost his cool at 4-4 and never recovered. Fedr needs to bring that first set level when it counts, if he can then the title is possible.
Federer was a bit grumpy after not getting the break at 3:1 in the second and started leaking errors and making dumb decisions, but he made up for it with an almost flawless third set where he made a whooping total of zero unforced errors
Filip had to finish (almost all his match) yesterday against Quentin Halys and Federer had won on Monday his first round. Krajinovic was dead beat, easy win for Roger, on his way to the SF with this cake walk draw. Not that bad in a way, so he could be fresh for a possible SF against Novak (or Stefanos)
Buddy Im not asking you to beat Federer, just take a set off, make him run a bit. We dont want to repeat the same tragedy what happened last year in London. Im worried because 39 year old Federer looked more fit than Djokovic in that Wimledon final, despite spending more time on court. We need Federer to play multiple epics before facing off with Djokovic.
