Aryna Sabalenka has extended one of the 10 longest No. 1 streaks in WTA rankings history. She reached the quarterfinals at the Mutua Madrid Open even without winning the title. That kept her at the top while she remained the deepest-reaching player among the WTA top five in Madrid. The race to the WTA Finals also shows Elena Rybakina in No. 1, with Sabalenka closing the gap.
