I wish there were a statistics engine for Tennis as there is one for Cricket. It would help answer my questions:
a) Is this the first time that a Grand Slam tournament has had eight nations represented in the quarter-finals of either the men’s or women’s draw?
b) If it were not for those pesky Russians, there might’ve been more than the 13 nations represented in the combined men’s and women’s quarter-finals this year! I find it hard to believe that more than 13 countries were ever represented at a Grand Slam quarter finals (men and women combined), don’t you?
