American tennis player and No.4 seed Sofia Kenin said her entry into the fourth round of the French Open was the result of the hard work she had put in on her fitness, and added that she was really playing some "good tennis".

The 22-year-old Kenin, who had lost the French Open final in straight sets last year to Poland's Iga Swiatek, said that she was satisfied with her game and the way she beat country-mate and No.28 seed Jessica Pegula for a berth in the fourth round on Saturday.
