Cameron Norrie out of US Open after straight-sets defeat to Andrey Rublev

• British No 1 was below his best in 6-4, 6-4, 6-4 defeat
• Rublev will face Frances Tiafoe in quarter-finals

Over the course of his glistening summer, Cameron Norrie's steady, gradual improvements have taken him to heights most never thought were possible two years ago. As he established himself as a Wimbledon semi-finalist, an undeniable top-10 player and an opponent who will grind you to dust and relish every moment of it, one of his greatest qualities has been the consistently high base level of his game. He has played few poor matches and he rarely takes bad losses.

In his first appearance in the fourth round of the US Open against one of the best players in the world, though, Norrie threw in a rare poor performance and was punished for it. Norrie fell routinely, with only a brief, angry surge at the close, losing 6-4, 6-4, 6-4 to Andrey Rublev.
