Elena Rybakina becomes world number one for the first time by reaching the US Open semifinals, despite defending champion and current top-ranked player Aryna Sabalenka still being alive in the tournament.

Elena Rybakina dominates Naomi Osaka to reach U.S. Open quarters, nearing her first world number one ranking.

Elena Rybakina already won this year’s Australian Open title, and is one victory from the No.1 ranking after reaching the US Open quarter-finals.
