Roland-Garros: Qualifier Day knocks out seed Keys, into third round

Qualifier Kayla Day reached the third round of Roland-Garros by edging out No 20 seed Madison Keys 6-2, 4-6, 6-4 in Paris on Thursday for the first Top 20 win of her career.

Day, ranked No 138, will play Slovak Anna Karolina Schmiedlova next.

In their only previous meeting, at the 2016 US Open, Keys had beaten her compatriot in just 48 minutes.

That was also the only time Day had previously had the second round of a Grand Slam.

Ahead of her victory, Day won against French wildcard Kristina Mladenovic (7-5, 6-1).

Keys, ranked No 20, defeated Estonian Kaia Kanepi (6-1, 3-6, 6-1) in the previous round of the French Open.
