The Hamburg European Open lost top seed Daniil Medvedev on Tuesday as the Russian went out 6-3, 6-4 in his opening match to Frenchman Ugo Humbert.
The ATP No. 5 was caught out by his 41st-ranked opponent, who beat Kevin Anderson and Fabio Fognini last week in Rome.
By contrast, Medvedev had no played since losing a US Open semi-final to eventual champion Dominic Thiem.
Medvedev lost serve three times in his 92-minute loss under the Hamburg lights on clay with the Roland Garros start looming on Sunday in Paris.
The Russian goes in with his single losing match on clay by way of preparation; hopes may not be high, with Mevedev losing in the first round at the major a in spring, 2019.
Humbert will play for a quarter-final place when he faces Czech Jiri Vesely in the second round.
