Dan Evans recovered from dropping the first set to reach the quarter-finals of the Rotterdam Open with a solid 4-6 6-3 6-4 victory over the world No.17 Karen Khachanov.
To make the last four he will have to overcome either the defending champion Gel Monfils or his French countryman, Gilles Simon who are scheduled to play Thursday evening.
Khachanov, who has had a spell in the top ten, was undoubtably the better player in the opening set but Evans, having got to grips with his opponent’s power game, used his superior speed and angled shots to make the big Russian uncomfortable.
An early break in the second set for the British No.1 stamped his own authority on the match to level the game and then took control of the decider when he broke for 2-1 lead with a beauty of a backhand down the line.
He maintained the pressure to extend that to 4-1 with Khachanov swiping his spare ball into the roof rafters in frustration when he again dropped his serve in the ninth game allowing his lower ranked opponent to serve out.
Meanwhile at the top of the draw, the top seed Daniil Medvedev suffered a surprise loss to Canadian veteran Vasek Pospisil as he was dispatched in 67-minutes 6-4 2-6 7-6(4)
