With regards to Tipsarevic, he had the benefit of being a top eight seed this year at the US Open, and Ferrer was his opponent in the quarter-finals. A golden opportunity, indeed.
With Nadal coming back, that pushes Janko out if the top eight, and also means he'll more than likely have to beat a top four member to reach the semi-finals. Something I don't think he's capable of in a grand slam.
Not unless he drops out of the top 12. Matches according to seeding:
R16: 5-8 play 9-12 and 1-4 play 13-16
QF: Winners of 5-8,9-12 play winners of 1-4,13-16.
Almagro has a better chance in my opinion, he's younger and has much more of a specialist Slam (needed for a big run). Almagro has beaten Murray at Roland Garros before (in 2008) and has been unlucky to draw Nadal in each of his best Roland Garros runs.
Yes, I know that already. I was eluding to something slightly different.
What I meant was his route to the semis would be harder. So in round four, as a 9-12 seed, he'd play a 5-8 seed. That's a lot tougher than being a 5-8 seed himself and facing a 9-12 player.
Consider it like this, there's a massive difference between playing Ferrer (#5) in round four of a grand slam and playing Monaco (#12) in round four of a grand slam. His quarter-final match would always likely be a top four player, but I feel his chances in that would depend on how fresh he is, so getting that easier fourth round match is crucial.
