Nine of the world's Top 10 players are included on the initial main-draw entry list for the bett1open in Berlin, the first WTA 500 event of this year's grass-court swing. Main-draw play begins on Monday, June 19.

World No.2 Aryna Sabalenka will lead the event in the German capital, which will take place on grass for the third straight edition. Sabalenka is currently No.1 in the Race to the WTA Finals, having won her first Grand Slam title at this year's Australian Open.

No.7 Ons Jabeur will return to Berlin as the defending champion. Jabeur claimed last year's trophy after Belinda Bencic retired with an ankle injury during the second set of their final. Half of Jabeur's four career WTA singles titles have come on grass, and she was also the Wimbledon runner-up last year.

No.3 Jessica Pegula, No.4 Elena Rybakina and No.5 Caroline Garcia are the other Top 5 players in the entries. Rybakina is scheduled to play on grass courts for the first time since she won the grass-court Grand Slam at Wimbledon last year.
