The Hologic WTA Tour clay season has seen four different champions win the four biggest clay-court events this season. Now the tour heads to Paris for the second Slam of the year at Roland Garros. 

Here's a look at everything you need to know. 

When does the tournament start?

The French Open is the second Slam of the season and is played at Stade Roland-Garros in Paris, France. The event features a 128-player singles draw, 64-team doubles draw, and 32-team mixed doubles draw. The tournament is played on outdoor clay using the Wilson Roland Garros ball. 

Main-draw play begins on Sunday, May 28. 

What is the format?

All singles, doubles, and mixed doubles matches will be played in a best-of-three tiebreak sets format. If the third set reaches 6-6, a 10-point tiebreak will be played. 

When are the finals? 

The singles final will be played on Saturday, June 10 at 3:00 p.m.

The doubles final will be played on Sunday, June 11 at 11:30 a.m.

The mixed doubles final will be played on Thursday, June 8 at noon. 

Who are the defending champions?

World No.1 Iga Swiatek is the singles defending champion. Last year, Swiatek defeated Coco Gauff 6-1, 6-3 to become the youngest woman to win multiple majors since Maria Sharapova. At 21, Swiatek became only the 10th woman to win multiple Roland Garros singles titles in the Open Era and the fourth youngest player to triumph more than once in Paris -- only Monica Seles, Stefanie Graf, and Chris Evert were younger.
