The ASB Classic have confirmed a second Top 10 ATP player will be heading in January next year with world number 8 Karen Khachanov returning.
The 23-year old Russian has long been touted as one of the future stars on the ATP.
"I've enjoyed playing the ASB Classic before and I'm happy to be returning. I missed it last year when I would have liked to have played. They have been very good to me from early in my career and I am really looking forward to coming back," he said.
"I have some great memories, my last match against Juan Martin in front of a full crowd at night was such a great atmosphere and I really hope I can do that again," said Khachanov.
Russian compatriot and current world number four Daniil Medvedev is expected to be the top seed at the tournament.
