Grass season: Tournament schedule, entry lists and what you need to know

The Hologic WTA Tour kicks off the grass season next week with seven tournaments across Great Britain, Germany, and The Netherlands. After six WTA events played across three weeks, it all leads to the third Grand Slam of the year at Wimbledon.

Here's what you need to know about the upcoming grass season:

What makes grass-court tennis unique?

Modern tennis was invented in the late 1800s in England and played on grass courts. Wimbledon is the oldest and most historic of the four Grand Slams. It was staged for the first time in 1877 at the All England Lawn Tennis and Croquet Club.

For those reasons, grass-court tennis is considered by many to be the purest, most traditional form of the modern game. The soft, natural surface yields a lower bounce, which can mute the effects of high-kicking topspin. The irregular bounces can wreak havoc on a baseliner's rhythm and precision. It also requires more delicate footwork around the court because players can lose traction with sudden stops and starts.

And because the natural surface wears down with each match, the wear and tear on the court can alter the surface as each day goes by. Because of the potential for irregular and awkward bounces, grass rewards a more aggressive game style that creates short points. It favors players with big serves, flat groundstrokes and good skills at the net.

That's a lot of variables to manage for a player in the best of circumstances, but the change is even more drastic coming straight after the clay season. With just three weeks of tournaments before Wimbledon -- and a scarcity of tournament-grade grass courts on which to practice -- much of the grass season is a race against time to get in as many matches and practices as you can.

Who are the WTA Tour's best grass-court players?

Only five active players have won more than two grass-court titles in their career: Venus Williams (5), Petra Kvitova (6), Angelique Kerber (3), Caroline Garcia (3), and Karolina Pliskova (3).

Among active players, Eastbourne's defending champion Madison Keys has an outstanding 75 percent win rate on grass, though, ironically, Wimbledon remains the only major at which she has not made the semifinals or better.

Not surprisingly, Wimbledon champions Rybakina and Kerber thrive on the surface, as does two-time Wimbledon finalist Jabeur.

Career winning percentage - Grass (Active Players)

1. Madison Keys: 75.0% (44-14)
2. Elena Rybakina: 74.2% (23-8)
3. Angelique Kerber: 73.0% (84-31)
4. Ons Jabeur: 72.3% (34-13)
5. Jelena Ostapenko: 70.3% (45-19)

Experience and success on grass varies greatly among the members of the current Top 10. World No.1 Iga Swiatek hasn't played 20 grass-court matches in her career. She's played more than 20 matches on clay this season alone. Australian Open finalist Zheng Qinwen is still in single digits.

But maybe experience is overrated. Just ask reigning Wimbledon champion Marketa Vondrousova. Even with her 7-0 run at the All England Club last year, she's still batting just .500 on the turf.

Current Top 10: Winning percentage - Grass

1. Iga Swiatek: 68.4% (13-6)
2. Aryna Sabalenka: 62.8% (27-16)
3. Coco Gauff: 66.7% (16-8)
4. Elena Rybakina: 74.2% (23-8)
5. Jessica Pegula: 57.1% (12-9)
6. Marketa Vondrousova: 50.0% (11-11)
7. Maria Sakkari: 55.0% (22-18)
8. Zheng Qinwen: 25.0% (2-6)
9. Ons Jabeur: 72.3% (34-13)
10. Danielle Collins: 42.9% (6-8)
