Petra Kvitova overcame the challenge of Laura Siegemund to ease into her first French Open semi-final for eight years.

The two-time Wimbledon champion is back in the last four at Roland-Garros for the first time since 2012 after recording a 6-3 6-3 victory on Wednesday.

Kvitova did not have to defend a break point in a comfortable first set and then came out on top of a more competitive second to beat the world number 66 in 80 minutes.

The winner of an all-American clash between Danielle Collins and Sofia Kenin will meet Kvitova in the last four.

A solitary break was enough to settle the first set, Kvitova claiming that in the fourth game when her German opponent sent a backhand long and wrapping up the opener in just 32 minutes with a forehand winner down the line.

Kvitova quickly racked up three break points in first game of second set and struck when Siegemund, who was playing in the second week of a grand slam for the first time, sent a drop shot into the net.

Siegemund did not fold from there, though, forcing four break points and taking the last of those to level matters at 2-2.

Kvitova made an instant response as Siegemund received a time violation and then took a medical timeout, only for the Czech to be broken for a second straight game in a stark contrast to the opening set, which produced just one break point in total.

She moved decisively in front when a volleyed winner secured her third break of the set at 4-3, from which Kvitova held serve and then duly broke again as a double fault ended Siegemund's challenge and sent the seventh seed through.
