It was battle of attrition between the players but Yuki overcame an early break in the second set to emerge winner after one hour 57 minutes.
After trading breaks, the first set was decided through tie breaker, in which Yuki prevailed when he converted his first set point on his rival's serve.
Yuki dropped his serve at love in the third game of the second set to hand Sugita advantage but made it even-steven when he converted his fourth break chance in the 10th game for a 5-5 scoreline.
Confident after getting back the break, Yuki served out the next game at love and the Japanese was now serving to stay in the match.
Sugita though wilted under pressure as he was down 0-40 and Yuki converted the second match point for a convincing win.
