Paris - Andrey Rublev jumped two places to a career-high 16th in the latest ATP rankings released on Monday.
The Russian won his second title in a week when he beat unseeded South African Lloyd Harris in the final in Adelaide on Saturday. That followed a title in Qatar the Sunday before and takes the 22-year-old's record this year to 8-0.
He is seeded 17 at the Australian Open where he faces Australian wild card Chris O'Connor in the first round on Tuesday.
Harris, meanwhile, jumped 19 places to a career-high 72nd. The other big mover lower down the rankings was Frenchmen Ugo Humbert who rose 14 places to 43rd after winning his first ATP tour title in Auckland.
The points gap between Rafael Nadal, Novak Djokovic and Roger Federer at the top remained unchanged from the previous week.
