Jo-Wilfried Tsonga earns commanding lead for France

Jo-Wilfried Tsonga has given France a 2-0 advantage against Czech Republic in the Davis Cup semi-finals after he eased past Lukas Rosol in straight sets.

Teammate Richard Gasquet had won the first rubber for his side with a convincing victory over Tomas Berdych, and Tsonga continued their momentum against Rosol.

The 29-year-old stormed through the opening two sets against his opponent, breaking serve on four occasions while dropping just eight points behind his serve.

Tsonga's dominance continued in the third, and one more break of serve was enough to record a comfortable 6-2 6-2 6-3 triumph.
