Two-time champion Serena Williams brushed aside Italy's Sara Errani to reach the French Open semi-finals at the Stade Rolland Garros here on Wednesday.
The top seed defeated the 17th-seeded Errani 6-1, 6-3 to maintain an unbeaten record in all their nine career meetings, reports Efe.
Williams, who won at Roland Garros in 2002 and 2012, will next face the winner between Timea Bacsinszky of Switzerland and Belgium's Alison Van Uytvanck.
