Aryna Sabalenka has not lost a straight sets match at a Grand Slam in five years.

Sabalenka won the US Open for a second time last week, after beating Amanda Anisimova in the final.

This is the first Grand Slam title that the Belarusian has won this year, with Sabalenka losing in two Grand Slam finals and one semifinal.

Despite losing three matches at majors this year, Sabalenka has still managed to at least win a set in every one.

Sabalenka has lost five straight sets matches on the WTA Tour already this year, but the world number one has been much more challenging to beat at Grand Slams.

Since losing in the second round of the 2020 US Open, Sabalenka has won 89 out of her last 104 matches.

Of those 15 defeats, Sabalenka has only lost one of those in straight sets, which came at the US Open five years ago.

Sabalenka was the fifth seed, but had never surpassed the fourth round of a Grand Slam tournament before.

This continued in New York that year, as Sabalenka was beaten by her compatriot and former world number one Victoria Azarenka, 6-1 6-3.

Azarenka went on to reach the final that year, but she is no longer ranked high enough to receive direct entry for Grand Slams.

Why has Victoria Azarenka fallen to her lowest ranking in seven years?

Azarenka is a former world number one and two-time Grand Slam champion, but she is far from that player at the moment.

The Belarusian is now a WTA Tour veteran at 36 years old, and Azarenka has struggled with injury more this year.

Azarenka has struggled to find form as well, having won only 11 of her 23 matches so far this year.

As a result, Azarenka is now ranked at world number 133, which is her lowest ranking since 2018.

This means that unless Azarenka climbs back up the rankings then she will need either a wildcard or a qualifier to play in the main draw of Grand Slams in 2026.

However, fans of Azarenka may have been encouraged by her performance at the US Open, having reached the third round before losing to fourth seed Jessica Pegula.
