Venus Williams took another step towards her first French Open title with a routine 6-2 6-4 victory over Spain's Arantxa Parra Santonja at Roland Garros.

Wearing an eye-catching black lace corset-style outfit, the second seed bossed most of the rallies as a stiff breeze lashed an overcast Court Philippe Chatrier, coming through in an hour and 35 minutes.

Santonja, who has an unusual double-handed grip on both wings, extended the American with some deft groundstrokes before Williams broke decisively in game seven of the second set, sealing the win when Santonja ballooned a return long.

She next faces Slovakia's Dominika Cibulkova in the third round.
