Sadly this will now give Dimitrov a false sense of his game. Gonna be a real blow to his ego next year when he falls back down the rankings to around 12-15 where he belongs. Seriously - WHO has he beaten this year? I looked it up - prior to the WTF his only 3 Top 10 wins came in the same tournament - Brisbane at the start of the year. Yes, that's right...prior to this week Dimitrov had not beaten a ranked inside the Top 10 at the time of their match.
Brisbane - 5 - Nishikori - F
Brisbane - 3 - Raonic - SF
Brisban - 8 - Thiem - QF
Other than these 3 wins the first week of January 2017 - prior to the WTF, he lost to every Top 10 player he played
AO - 9 - Nadal - SF
Madrid - 9 - Thiem - R16
Wimbledon - 2 - Federer - R16
Beijing - 1 - Nadal - Final
Shanghai - 1 Nadal - QF
Other players he beat at big tournaments?
Sofia - 11 - Goffin - F
Cincy - 23 - Kyrgios - F
Other players he lost to in early rounds?
Rotterdam - 11 - Goffin - QF
IW - 18 - Sock - R32
RG - 23 - Carreno Busta - R32
Stockholm - 19 - DelPo - F
Paris - 14 - Isner - R16
So pardon my skepticism about Dimitrov's chances of remaining in the Top 10 - let alone to Top 3-4 - when Murray, Djokovic, Wawrinka, etc., return next year. Espeically since DelPo will most likely make his move to get back into the Top 5. He has 0 points to defend at the AO and Dimitrov has 720 points to defend. As much as I've side-eyed Nadal's return to #1 in this injury-filled year...my eyes are literally going to get stuck in the back of my head if anyone claims that Dimitrov will be in the Top 5 this time next year. He played 22 regular events this year - and didn't make it past the R16 in 12 of them. THAT is how decimated the men's game has been this year. 1 big win and they're in the Top 10 doing their "I"m the kind of the world!" routine. If Dimitrov successfully defends his Cindy title I'll need smelling salts to bring me out of a stupor.
The results you compiled can be read in a different way. I agree with you that they show that Dimitrov is not a world beater, but I guess they also show that he is one step away from being a really high level. That last step is the hardest one, I agree, but you can safely argue he has never been that close. Take a look at the top 10 losses list:
AO - 9 - Nadal - SF
Nadal ended up as the #1 player in the world and was playing pretty well. The match was epic and decided in a close fifth. Nothing to be ashamed of, quite the contrary.
Madrid - 9 - Thiem - R16
Thiem was playing like hell on clay and his matches against Nadal, including a win, show that. Apart from Nadal pretty much everyone else on tour would have lost here too. Nothing to be ashamed of.
Wimbledon - 2 - Federer - R16
No need to comment.
Beijing - 1 - Nadal - Final
Competitive match against a guy fighting to be world #1 who happens to be one of the greatest in history.
Shanghai - 1 Nadal - Q
As above.
So, yes, obviously some room for improvement but it is not like the guy is being spanked and losing matches he was supposed to win all the time. I agree with you that #3 in the world is a bit illusive, as there are a few guys out, but even if all of Djokovic, Murray, Wawrinka, Nishikori and Raonic would have finish ahead of him (not a given) he would still be #8, which is a step ahead from previous seasons.
If he gives one more step forward, than he is a genuine slam contender (specially in the post FEDAL era). But, again, I agree that one more step is missing. But that is true for just about everyone else.
