There were no shocks in the German Tennis Championships on Thursday as Martin Klizan and Guillermo Garcia-Lopez both eased through their second-round matches.
Seventh seed Klizan needed just 50 minutes to see off wildcard Louis Wessels 6-1 6-1, while eighth seed Garcia-Lopez brushed Grega Zemlja aside 6-2 6-2 at the clay-court tournament in Hamburg.
Inigo Cervantes could not build on his shock victory over Alexander Zverev as he was beaten in three sets by Stephane Robert, the Frenchman triumphing 7-5 4-6 6-1.
But there was better fortune for Cervantes' Spanish compatriot Daniel Gimeno-Traver.
Gimeno-Traver emerged victorious in the longest match of the day, coming from behind to beat qualifier Daniil Medvedev 5-7 7-6 (7-4) 7-6 (7-2) after over three hours of play.
