British number two Dan Evans reached the Stockholm Open quarter-finals after coming through a testing encounter with Spain's Alejandro Davidovich Fokina.
Fourth seed Evans, 31, coming off successive first-round exits in his previous two events, recovered from going a break down in the first set to win 7-6 (7-5) 6-2.
He will face American eighth seed Frances Tiafoe next.
Compatriot Andy Murray faces top seed Jannik Sinner later on Wednesday.
The 34-year-old Scot, playing in what is set to be his final event of the year, said 20-year-old Italian Sinner was "one of the best players in the world".
