Keys reaches first French Open quarter-final

On the run: Madison Keys of the US plays a forehand return to Romania's Mihaela Buzarnescu

American 13th seed Madison Keys reached the French Open quarter-finals for the first time on Sunday with a 6-1, 6-4 win over Romania's Mihaela Buzarnescu.

Keys, the US Open runner-up last year, will face either Czech 26th seed Barbora Strycova or Yulia Putintseva, the 98th-ranked Kazakh, for a place in the semi-finals.

The 23-year-old American has now reached at least the last-eight of all four majors.
