Iga Swiatek continued her march towards a second French Open title in three years when she demolished Russian Daria Kasatkina 6-2, 6-1 to reach the final and extend her winning streak to a jaw-dropping 34 on Thursday.

She will face Coco Gauff who crushed Italy’s Martina Trevisan 6-3, 6-1 in the title clash on Saturday.

The world No.1 conceded an early break, but made the most of Kasatkina’s string of unforced errors, peppering court Philippe Chatrier with winners. Poland’s Swiatek, the 2020 champion, has not lost since February and has matched Serena William’s winning run from 2013, having now lost only two sets in her last four tournaments.

She will meet either American teenager Coco Gauff, the 18th seed, or Italy’s Martina Trevisan in Saturday's showdown. Swiatek again played with a ribbon in the colours of the Ukrainian flag pinned to her hat against her Russian opponent.

Russian and Belarusian players are allowed to compete at Roland Garros but will have to sit out Wimbledon as All England Club officials barred competitors from the two countries due to Russia’s invasion of Ukraine, which Moscow calls a“special military operation”.

Belarus has been a key staging area for the invasion. “Pretty special moment. Yeah, I’m really emotional. I’m so grateful to be in this place and you know, be healthy and be able to play my game. It’s amazing and I love playing here,” said Swiatek.

“Right after my first year there was Covid-19 and I was not able to see how many Polish people would come. It’s overwhelming.

“I try to treat every match the same way. When I realise this is one of the biggest matches of the season, it could stress me out.”

Swiatek started with a double fault but held and broke in the second game, only for Kasatkina to break back and level for 2-2.

The Russian’s game, however, was riddled with unforced errors and Swiatek collected free points to steal her opponent’s serve again for 4-2. She then won eight points in a row to wrap up the opening set with a crosscourt backhand return that left Kasatkina with her feet stuck on the red dirt.

American teenager Coco Gauff crushed Italy’s Martina Trevisan 6-3, 6-1 to become the youngest French Open finalist in 21 years.

Gauff, who has yet to drop a set in the tournament and is the youngest finalist at any grand slam in 18 years, needed time to find her range, trading two early breaks each with Trevisan. Once she found a way to neutralise the left-hander’s punishing forehand, however, Gauff breezed through the first set by winning the last three games.

The 28-year-old Trevisan, bidding to become the lowest ranked finalist in the event's history, took a medical break to strap up her right calf.

But things just got worse for her as she piled up 35 errors by the middle of the second set. Ranked 23rd in the world, Gauff broke her again and never looked back.
