Yuki, who had won the Pune Challenger last week, lived upto his third seed billing and defeated Balaji 6-3 6-2 in the relatively easy first round encounter.
Yuki had clinched his first title of 2017 on the ATP Challenger Tour after registering a come-from-behind win over compatriot Ramkumar Ramanathan in the final of the KPIT-MSLTA Challenger in Pune.
Yuki is currently ranked 122nd in the world after he had registered a win over Frenchman Gael Monfils and pushed Denis Shapovalov and Kevin Anderson to deciding sets in the Davis Cup and Citi Open respectively. He was ranked 474th at the start of the year.
"I had this injury and I tried hard for a couple of days but I don't want to take any risk," Myneni said.
