Cameron Norrie recorded his first win of 2022 by beating Ugo Humbert in straight sets in Rotterdam.
The British No 1 had been beaten in the first round of the Australian Open after losing all three of his matches at the ATP Cup.
But Norrie, who lifted two ATP titles in a stellar 2021, returned to winning ways by easing past Frenchman Humbert 6-2 6-4.
The world No 13 broke in the first game of the match and raced into a 4-0 lead on his way to taking the opening set.
Humbert fought back in the second and led 4-1 after a break of serve, but Norrie reeled off five games in a row to book his place in the last 16, where he will face Karen Khachanov or Alexei Popyrin.
Fourth seed Hubert Hurkacz saw off Jo-Wilfried Tsonga of France with a 6-4 7-6 (9-7) victory and will play Italian Lorenzo Musetti or Mikael Ymer of Sweden in the last 16.
