Iga Swiatek continued her incredible run at Roland Garros as she reached the semi-finals with a straight-sets win over qualifier Martina Trevisan.
The 19-year-old, who thrashed top seed Simona Halep in the previous round, proved too strong for Trevisan as she won 6-3, 6-1 in an hour and 18 minutes.
Swiatek, who is yet to drop a set, will now face another qualifier, Nadia Podoroska, for a place in the final.
The Polish teenager should start as favourite for that contest given her impressive form so far. She has only dropped 20 games in five matches and her powerful hitting proved too much for Trevisan, who upset fifth seed Kiki Bertens in the previous round.
Highlights: Polish teenager Swiatek powers into French Open semis
With both players taking part in their first Grand Slam quarter-final, and having to wait for the conclusion of the marathon match between Dominic Thiem and Diego Schwartzman, it was little surprise that the start of the contest was scrappy.
Trevisan broke in the opening game and was striking the ball cleaner as she moved 3-1 ahead.
But Swiatek started to find her range, particularly on her powerful forehand, and turned the set around by winning four games in a row.
Trevisan, who hadn’t won a main-draw match at a Grand Slam before this tournament, had two chances to break back at 5-3 but failed to convert. Swiatek took her third set point and then won the opening three games of the second set to establish firm control of the match.
A break in the fourth game gave Trevisan hope of staying in the contest but she couldn’t stay with Swiatek as she continued to control rallies and eventually wrapped up the match.
Expert analysis - An amazing performance from Swiatek
Eurosport analyst Tim Henman: "Swiatek has just played fantastic tennis, there is so little experience at this level but she looked like she had been doing it for years and years.
"She kept control and when she got on the front foot she wasn’t scared to go down the line, which is the riskier shot, but she never seemed to make the errors and it was an amazingly complete performance.
