Unstoppable? Swiatek heavy favourite for second French Open title

Riding a 28-match unbeaten run into Roland Garros and a winner of her past five tournaments, Iga Swiatek is the undeniable favourite for a second French Open title in three years.

Since the shock retirement of world number one Ashleigh Barty, the 20-year-old Swiatek has swept aside all-comers and transformed herself into the player to beat in women's tennis.

The Pole hasn't lost since falling to another former Roland Garros champion, Jelena Ostapenko, in Dubai in February. Her winning streak is the longest on the WTA tour since Serena Williams won 34 matches in a row in 2013.

"It's pretty hard to describe it because all these tournaments that I've won seem pretty surreal right now. I feel like just continuing the same things that I did before really was the key to that," Swiatek said after defending her Rome crown.

She is only the second player to win four WTA 1000 titles in a season. 

Swiatek dominated on the hard courts in Doha, Indian Wells and Miami, and made a seamless switch to clay -- her triumph in Rome came after she skipped Madrid to rest following another victory in Stuttgart.
