1. Marcos Baghdatis was fined $600 for smashing four racquets during his match against Stan Wawrinka. Good. It's about time the powers that be paid more attention to racquet rights.
2. I had David Nalbandian beating Sam Querrey in my bracket, and if it weren't for that umpire pulling rank on a suspect overrule (and subsequent refusal to let Nalbandian challenge the call), it might have been right. He got screwed! Two questions arise here: (a) Do you think that umpires sometimes just don't like certain players and it affects the decisions they make? (b) If one of the Big Four had waited that long to make a challenge -- which, by the way, was, what, a few seconds? -- would the same thing have happened? Heck, I've seen players walk up to a line, walk over to their posse, consult, stop at their chair for a drink of water, stretch, then ask for a challenge. What we need is a specific amount of time to challenge a call, and it would need to be different for singles and doubles. That's it!
3. Sam Stosur. *face palm*
