The fourth seed Indian was leading the world number 67 6-4 3-4 after one hour and eight minutes when skies opened up and despite efforts made by the organisers, the match could not be re-started.
The match will be completed tomorrow. Yesterday also Yuki had to play two mathces in a day and he won both.
Yuki raced to a 4-1 lead in the opening set, courtesy a double break -- third and fifth games -- but the exeprienced Uzbek clawed his way back in the match by breaking the Indian in the sixth.
However, Yuki remained solid, fighting fire with fire and also negated a few close calls which went against him.
