Dementieva battles in quarter-finals

Russia’s Elena Dementieva had to dig deep to reach the quarter-finals of the French Open after dispatching compatriot Vera Zvonareva in three sets.

Seventh-seeded Dementieva took the early initiative but let her lead slip before rallying in the third to claim a 6-4 1-6 6-2 victory that sets up another all-Russian last-eight clash with either Dinara Safina or world number one Maria Sharapova.
