French Open 2014: Agnieszka Radwanska becomes latest top seed to lose at Roland Garros

The third seed was the highest ranked woman remaining in the competition

The top three women's seeds are all out of the French Open after Agnieszka Radwanska lost to Ajla Tomljanovic in the third round.

While not as big a shock as either Serena Williams or Li Na's exits, it was a sizeable upset nonetheless and leaves fourth seed Simona Halep as the highest-ranked player left in the tournament.

Radwanska has never enjoyed playing on clay, particularly in the slow and heavy conditions that have been a feature of the first week at Roland Garros this year.

She reached the quarter-finals for the first time last year but was on the back foot from the start against 21-year-old Croatian Tomljanovic and went down 6-4 6-4.

It was a breakthrough at the top level for the Croatian world number 72, who is through to the fourth round at a grand slam for the first time at her maiden French Open.

This has been a tournament where the young guns have made their mark, and the powerful Tomljanovic joins Garbine Muguruza, Kristina Mladenovic and Taylor Townsend as a headline maker.
