"It's very difficult, these are pretty fast conditions", Ljubicic said. "The match before me was 2 tie-break sets, [Andreas] Seppi and [Oliver] Marach also 2 tie-breaks, so it's really difficult to play against the serve. Of course Sam and myself are serving pretty big too so that doesn't help. You have to be careful to not lose concentration as a couple of lucky shots can change the whole match. In the tie-break my experience won me the match, but he has great potential; his serve and forehand are really, really big."
