The 23-year-old Yuki, who lost to Belgium's Joris de Loore, was a finalist at the USD 50,000 ATP Challenger event last year.
Saketh Myneni, though, made good progress as he gained eight places to rise to a career-best rank of 158 after ending runner-up at the just-concluded tournament at DLTA Complex.
Both Yuki and Saketh were sanctioned a financial assistance of Rs 37 lakh and Rs 36 lakh respectively last week by the government from the National Sports Development Fund (NSDF).
Also moving up was comeback man Mahesh Bhupathi, who won the doubles title with Bhambri. The 41-year-old Bhupathi moved to 226 after making a jump of 61 places.
Bhambri also benefitted with the win as he entered the doubles top-200. He gained 46 spots and was now placed 198.
Meanwhile Somdev Devvarman, who opted not to defend his Delhi Open title, suffered a massive slump. He has slipped to 279 after a loss of 87 places on the ranking ladder.
