Madison keys USA vs Daria kasatkina RUS
Head-to-head: first meeting
Key Stat: Keys has won back-to-back three setters in her last four events.
The two youngest players remaining in the draw will square off in a matchup that tennis fans will likely see—and enjoy—quite a bit over the next ten years. No. 7 seed Madison keys has had her mettle tested early and often here in Rio, but each time she has been pushed, the 21-year-old power broker has pushed back, gutting out back-to-back three setters in her last two matches and showing poise and patience to go with her world-class attack. Speaking of poise, 19-year-old Daria kasatkina has proven to be a quick study on the Olympic stage. The Russian methodically eased past Italy's sara Errani to reach the quarterfinals on Tuesday, proving once again that she's every bit as good as her ranking, and perhaps even better. But how will Kasatkina handle the grooved ground game of Keys? Will she be able to keep the hard-hitting American off balance, or will she find herself in over her head against a blossoming American who is willing to lay everything on the line in the quest for an Olympic medal?
