Victoria Azarenka and Amanda Anisimova both cruised into the second round as they prepare for Wimbledon.
Starting with two time grand slam champion Victoria Azarenka who enters this week after winning the doubles title with Aryna Sabalenka in Berlin.
Azarenka continued her momentum with a 7-5 6-0 win over compatriot Yuliya Hatouka.
The world number 14 struggled in rainy conditions in Germany in the first set as she was broken three times in the first set.
It was a tough start from Azarenka who couldn’t consistently blast past the world number 271.
In the end Azarenka saved some break points and broke in her following two return games to seal the opening set in 53 minutes.
However the second set was much easier as she didn’t concede a single break point and won all six games.
Azarenka will now play Alize Cornet in the second round.
Meanwhile 19 year-old Amanda Anisimova is looking for a good grass court season after crashing down to 81st in the world.
The American sealed a 6-1 7-5 win over German veteran Andrea Petkovic as she moved into the last eight.
Anisimova produced a high-quality first set as she stormed into a 4-0 lead in the opening set.
After sealing the opening set in 24 minutes, Anisimova continued the momentum by breaking in the opening game of the second set.
However Petkovic has shown good performances on a grass court in the past and she remained resilient to break back for 4-4.
Despite that setback, the American broke in the eleventh game and closed out the match to love.
Anisimova will play Angelique Kerber or Anna Blinkova next.
In other results Katerina Siniakova edged past Jessica Pegula 6-3 5-7 6-4 and will meet Laura Siegemund in the quarter-finals.
Siegemund booked her place in the last eight with a 6-2 6-2 win over Tamara Korpatsch.
