Live: Djokovic Leads Berdych

World No. 1 Novak Djokovic leads Tomas Berdych 6-3 in their Roland Garros quarter-final on Wednesday.

The Serb broke through in the seventh game of the opener and broke the Czech again in the ninth game to take a one-set lead.

The 29-year-old Djokovic has won his past 10 meetings with Berdych and leads their FedEx ATP Head2Head series 23-2.

Djokovic is bidding to reach his 30th Grand Slam semi-final and his eighth at Roland Garros, where he has been runner-up three times, in 2012 (l. to Nadal), 2014 (l. to Nadal) and 2015 (l. to Wawrinka).

The Belgrade native is currently on a 25-match Grand Slam winning streak, with his last loss at a major coming 12 months ago in the Roland Garros final. He is looking to become the eighth man in history to complete the career Grand Slam with victory in Paris.

The 30-year-old Berdych is looking to make the semi-finals in Paris for the first time since 2010, when he lost to Robin Soderling.
