Nick Kyrgios has fought back to beat Ukraine’s Alexandr Dolgopolov and advance to the third round of the Cincinnati Masters.
Kyrgios recovered from dropping an early break in the first set to win 6-3 7-6(6) in a match which saw both players bemused to learn they had been serving with women’s balls for six points.
While the balls used on the men’s and women’s tour generally have the same size and pressure, the men usually use extra-duty felt to slow the speed of the ball down while the women use regular-duty balls which have a different logo.
