Rybakina Secures Year-End No. 1, Then Withdraws from Finals

Rybakina clinched her first year-end No. 1 by beating Putintseva 6-2, 6-3 in Tokyo, then withdrew from her Tokyo quarterfinal against Fernandez; the reported neck injury remains unverified. She also withdrew from the Finals, with reports citing a viral illness and Rybakina saying her body was not ready; Kostyuk replaced her. Swiatek, ninth in the Race, would have been next in line but was unavailable after ending her season following a thigh problem.
