Andrea Petkovic was eliminated in the first round at her Wimbledon dress rehearsal in Bad Homburg.
The 34-year-old tennis player from Darmstadt lost 6-1, 6-2 in her Hessian homeland against the top seeded Russian Daria Kasatkina.
The high point of the grass season at the All England Club begins for Petkovic and Co. on June 27 in south-west London.
Angelique Kerber is also preparing for Wimbledon in Bad Homburg. The three-time Grand Slam winner starts the tournament on Monday as the defending champion against qualifier Anastasia Gasanova.
Kerber won the premiere in Bad Homburg, where she also acts as a tournament ambassador, last year and then moved into the semi-finals of Wimbledon.
