Swiatek, Kontaveit and Ostapenko could potentially replace Barty as No. 1 after her withdrawal from Indian Wells and Miami

Ashleigh Barty pulled out of Indian Wells and the Miami Open which complicates things in the rankings especially if Swiatek, Kontaveit and Ostapenko have good runs.

French Open champion Barbora Krejcikova has moved ahead of Aryna Sabalenka into the world No. 2 spot. Iga Swiatek has jumped four spots to equal her career-best ranking of No.4 after winning in Doha, while runner-up Anett Kontaveit is up into fifth. Jelena Ostapenko, who has been in excellent form this month, is up into No. 12.

Swiatek, Kontaveit and Ostapenko could be the ones to watch over the next few months in the pursuit of Barty. Ostapenko and Kontaveit both have opportunities to move further up the rankings if they can improve their records at the French Open and Wimbledon. Ostapenko lost in the first round of the French Open and the third round of Wimbledon last year; Kontaveit did the same in reverse.

For Barty, the battle to stay as world No. 1 starts again now, just as it did around this time last year when Naomi Osaka was aiming for the top spot at the Miami Open.
