Is it over for Kerber? Today's performance was shameful, she looked like she didn't even care. Kontaveit would hit a DTL shot and Kerber would instantly just turn away for the next point; not even attempting to go for it. She's almost 32 years old now and has an extremely taxing game on the body, can you really see her doing much else from now on? Or will she retire by the end of the year, or perhaps after the Olympics in 2020?
