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.
Yep. Massive opportunity, and that was a heart-breaker. As far as we know (up to now), I don't believe he can ever reach a slam semifinal, even with/without Nadal being present. Hell, I'm not even sure he's capable of reaching another QF anymore.
But then again, who knows what the future holds. But currently Tipsy is definitely closer to date compared to Almagro, given how their respective QF matches have panned out.
