THE LOW DOWN: Juan Martin hits a new low, becomes a mama-basher

Now how could you insult this innocent-looking woman? Juan Martin Del Potro saw something so mean, so evil in Judy Murray that he did something you never do: insult someone's mama.

During last night's first round match between Juan and Andy Murray, things got heated after an exchange at the net according to Andy:

I played a serve-and-volley and hit a bad volley in the middle of the service box and he came in and hit a full-power backhand straight at my head. I would have thought it's normal to apologize for something like that, and not to get an apology was a little bit disappointing. After that, the next two or three points I was maybe shouting, "Come on," a little bit more than I usually do.

Apparently the incident led to the insult and Andy was understandably bothered:

Someone saying something about your mother who is one of the nicest ladies you're ever going to meet? I don't think that's really that cool.

Yeah that was a low-blow Juan, you mama-basher.
