Has any player won all ATP masters events?
 

I assume Federer is the closest one to it, but im not sure. Anyone have any idea?

http://en.wikipedia.org/wiki/ATP_World_Tour_records

Federer and Djokovic are 9/9 in finals reached, Nadal is 8/9.

Different titles won: Federer, Agassi, Djokovic 7/9

Federer is missing Monte Carlo (reached 3 consecutive finals - lost all 3 to...wait for it...Nadal, reached 2 Rome finals - 1 lost to Mantilla, 1 lost to Nadal)
Djokovic is missing Monte Carlo (2 finals lost to Nadal I think) and Cincinnati (4 finals lost...2 to Federer and 2 to Murray I think).

I don't think Federer has it in him to win Monte Carlo and Rome even without Nadal in the draw, he's not even playing MC btw.
I could see Djokovic winning Monte Carlo if Nadal is not in the draw or he's not in good shape (I assume 2013 is his best chance). In Cinainnati Djokovic has just been plain unlucky, reached the final on 4 out of the last 5 editions and twice lost to Murray/Federer. He should win it at least once in the future.

Djoker looks set to be the first guy to win all 9. Would be cool to see.

Another reason why Djoco should be considered among the best, he is about to achieve a feat no player in the open era has done.

It is an obscure feat, one step better than "winning all 500s". Masters are way behind Slams and WTF in terms of what players try to peak for; one of them is even optional. Nobody would trade a single Wimbledon victory for 9 Masters. Most people (excluding us, hardcore tennis fans & pundits) would be unable to name most of them, maybe except Indian Wells since the name is so catchy.

if it was Federer, everybody would be up his @rse about this.

Lol...exactly!

daniel nestor. ;)

Let's actually wait till he actually does it.
Lot's of players are ABOUT to achieve something

All of Agassi, Federer and Djokovic have won 7 out of the 9. Federer has never won M-C or Rome. Agassi didn't win M-C and Hamburg (3rd clay master). Djoko has never won M-C and Cincy. So far no one has won 8 out of the 9. I hope an active player will do it. (oops sorry I hadn't seen tennis pro's post. Sorry for the repeat.)
ETA: Nadal and Federer are the only 2 players who've won 5 different masters more than once. (Sampras, Agassi and Djoko: 4)

With all the finals he's made in Cincy, one would think, one day, he would manage to win one!

Nole and Fedex can do it. But, in my opinion, Nole has the easier way to do it, 'cause he already played Cincy finals for 5 times, and Fedex has to win 2 masters on clay.

Fed already should have won Rome06 and MonteCarlo08
If he loses early in Indian Wells, i hope he either enters Miami or Monte Carlo

Novak has played 4 finals in Cincy: 2008, 2009 and 2011, 2012. He lost to Fed in 2009 and 2012 and to Murray in 2008 and 2011 but actually the 2011 one was a retirement.

that damn Monte Carlo...one can only dream.

The name should be changed to "The Rafa Nadal Invitational"

Rafa should make a cameon if they include Monte Carlo as a location in any further James Bond flicks. Random, I know...

You're probably right there, but it's still a bit of a "2nd tier" stat (for lack of a better term.) It would be a great accomplishment, but it's not something that people would use objectively to bolster Djokovic's GOAT status to any great effect.

Cincy is tennis valhalla

On the one hand, it is kinda awesome if you can say that you've won all the Masters and Grand Slams (which will probably be the case for novak) but on the other hand players don't think of it as that much of a record seeing that Federer isn't even trying to go for it.
