Why aren't you happy? Andy had a real surgery and didn't play any competitive tennis for about 3/4 months. It needs its recovery time, no? Del Potro took a year to recover fully from the wrist surgery and another year just to get things back on track upon return. It's a process after all.
Anyway, I would have liked him to win a couple of more matches here now that Verdasco is out too, but oh well.
On another news, Ferrer is out in straight sets to Daniel Brands. Brands is capable of playing sublime tennis at times, yes.
