Yes, normally you can't meet with your coach, but we are talking Maria Sharapova here- the darling of the WTA.
The camera showed Yuri's seat was empty during the bathroom break, and the commentators hinted that he might have left to talk with her. Then there was a bit of awkward silence.
We all know that he bends the coaching rules frequently. Even if he said something to her while she passed by on her way to the bathroom, that's coaching and would be against the rules. If he spoke Russian, no one can prove he coached unless there was a Russian speaking person right there.
That match left a bad taste in my mouth. Maria was never my favorite, but I always had a lot of respect for her. That's eroding now. She's only one stunt or suspect play away from being on par with JHH in my book.
