Yes, there were some bad calls but she also made 57 unforced errors. So let's not just blame the umpire for the calls. Bad calls are part of any sport, you gotta deal with them and move on.
I'm glad she lost. She rubs me the wrong way. What she did in the Olympics was pathetic. She never had any intention of going and she waited until the last minute to withdraw, waiting so long in fact that the US couldn't name a replacement. I'm sure that somebody would have loved to be on the team but her selfish attitude cost somebody a spot. She can't lose enough to suit me.
