It's OK, honey...we do the Aussie summer zombie thing for a few weeks out of the year, and you do it the whole rest of the calendar. I know it sometimes helps that you pull night-shifts, for tennis-viewing, but that can't be easy, either.
I agree with you that Ruud played very well today...maybe his best of the clay season? While I'm inclined to agree with
@Kieran that the winner of this semi, (Ruud v Zverev) is likely to the the runner-up on Sunday, I'd actually pick Ruud as the sturdier finalist. Zverev has bigger weapons, but more down-side.
