Naomi Osaka is about to start her Miami Open campaign, and she needs to have a deep run if she wants to be sure to retain her world no.1 rank since there are 4 players that can take over the top spot of the rankings after this event.
Here the basic scenarios.
Osaka
Naomi will retain her world no.1 rank if she reaches the final in Miami or she gets to the quarters and Kvitova, or Simona Halep do not win the tournament.
If Naomi reaches only the round of 16, she can still stay no.1 if Kvitova doesn’t get to the final and Halep or Kerber do not win the tournament.
Kvitova
Petra will become the new world no.1 if she wins the tournament
Otherwise, she can be the runner-up, but Naomi needs to crash out in the round of 16 and Halep and Kerber do not win the Miami Open.
Halep
Simona will get back her world no.1 rank if she wins the tournament and Osaka is not the runner-up.
Another option for the Romanian is that she reaches the final, but Osaka loses in the round of 32, and Kvitova or Angelique Kerber do not win the tournament.
Kerber
Angelique can also regain her world no.1 rank only if she wins the tournament and Naomi Osaka doesn’t reach the quarters.
Svitolina
Elina can become the world no.1 if she wins the tournament, Kvitova is not the runner-up, and Osaka doesn’t reach the round of 32.
The overall feeling is that Naomi will stay at the very top also after the Miami Open.
