There is still a big gap between the top 4 and the rest (even if Andy is someone floating away from the top 3 right now), that Ferrer is trying to bridge with minor ATP events, it would seem.
Points after Wimbledon
in 2011 Djoko 13,285, Nadal 11,270, Fed 9230, Murray 6855, Ferrer 4150
in 2012 Fed 11,075, Djoko 11,000, Nadal 8905, Murray 7460, Ferrer 5455
So points are all closer this year than last.
I posted this elsewhere , but this is what Ferrer said on Sunday - "I work to improve my game. I don’t work to be in the Top 4. I work to be a better player and nothing else. I think the Top 4 are amazing players, and they are better than everyone else at this moment. I don’t think about the Top 4, I think about me and the Top 10".
He could pick up quite a lot more points at Toronto, Cincinnati and the US Open though, while Andy has more to defend.
