Starting in 2024, adjustments to the rankings points will be made in an attempt to allow for a more simplified system that creates more alignment across tennis -- between WTA, ATP and ITF. Part of that adjustment is rewarding the champions at each level will reflect the classification level of each tournament, with the winner of a WTA 1000 event receiving 1000 points, the winner of a WTA 500 earning 500 points, WTA 250 earning 250 points and WTA 125 earning 125 points. 

This past week, Elena Rybakina collected 500 points by winning Brisbane as she moves up one spot to No.3, overtaking Auckland champion Coco Gauff, who earned 250 points by winning the title at Auckland and moves to No.4.

No.1 watch

Current World No.1 Iga Swiatek won all five of her singles matches at United Cup last week, helping Poland reach the final and, as a result, earned 500 points. Meanwhile current No.2 Aryna Sabalenka picked up 325 points as runner-up at Brisbane.

Swiatek, who secured the year-end No.1 ranking by winning the WTA Finals championship match, now holds a 975-point lead over Sabalenka.

Must See

With Swiatek defending 240 points in the remainder of January from fourth-round points at the 2023 Australian Open, she will hold on to the top spot through the Australian Swing, bringing her career total at No.1 to 88 non-consecutive weeks (including the week of Jan. 28).

The closest contenders -- Sabalenka (2000) and Rybakina (1301) -- have too many points to defend and the gap for the others in the Top 5 remains too large. 

Here is a look at who is defending the most points during the remainder of the Australian swing:

Sabalenka: 2000 (Australian Open title)

Rybakina: 1301 (Adelaide second round, Australian Open runner-up)
