Tennis young guns Karen Khachanov and Hyeon Chung have signed up for next year's ASB Classic tournament, meaning half of all entrants to the inaugural ATP Next Gen Finals will be present in Auckland.
The 21-year-old Khachanov will return to New Zealand for the second consecutive year, while Chung will make his Classic debut.
Both are playing in this week's Next Gen Finals in Milan, as are fellow Classic participants Andrey Rublev and Denis Shapovalov.
The event, in its first year, brings the tour's best eight young players together.
"Khachanov for me, along with Shapovalov, are the two guys to watch out for - I think he has the potential to win Grand Slams. He has a really big game and he has a thunderous forehand," Classic director Karl Budge said.
"It's no surprise he is being compared to the iconic Marat Safin."
The men's event will begin on January 8.
