Looks like it will be a good match. Hope Wawrinka in ailing from his Chardy match because I would want Andy to progress comprehensively through to the semis. To be honest Andy has been let off at this tournament in my opinion because so far he hasn't faced a single difficult player and looking ahead to the SF/F he doesn't seem to be competing against anyone he can't beat. As well as that this tournament will be good practice for Shanghai.
Odd. He's only just got to the round where he'll play a seeded player. Look at all the non-seeded players and Karlovic is actually probably one of the tougher ones.
And as for the rest of your comment.. well, ye. He's #3 in the world and the most in-form player on the planet right now. He's the top seed. Of course he's going to be competing against players who he should beat. That said, Tipsarevic and Berdych are two potentially very tough matches. Berdych is obviously one of the best players outside the top 4 and Tipsy isn't far behind. Berdych still has a winning H2H against Andy. Let's not take things for granted.
