Who is Aryna Sabalenka? Why is she called 1st `Neutral` Grand Slam Champion?

Aryna Sabalenka scripted a brilliant comeback to win her maiden Australian Open singles title after defeating Jelena Rybakina in the final on Saturday. With the Russia-Ukraine conflict not showing any signs of slowing down, all Russian and Belarusian players are forced to compete without any national affiliation and as a result, Sabalenka became the first player in history to win a Grand Slam while competing under a neutral flag.
