#3 Ruby Riott/The Riott Squad
Ruby Riott is one of the most talented women in WWE who has at least nine years of wrestling experience. That's incredible for the superstar as she was born in 1991 and has been wrestling since 2010.
Ruby has won numerous championships in different promotions outside WWE. Since most promotions have only a single championship for the women competing on their roster, it shows that she has been one of the best in all the promotions she has worked on.
She made her way into WWE in December 2016 on NXT and soon made her main roster debut on SmackDown less than a year later alongside Liv Morgan and Sarah Logan. The trio currently features on Raw as The Riott Squad.
Ruby can surely become a future Raw Women's Champion, but since the championship is held by Ronda Rousey and there seems to be a long line of successors waiting for their chance, it seems like 2019 may not be her year as a singles champion.
However, with the Women's Tag Team titles on their way, The Riott Squad could be front-runners for the title and the three women can easily win the championships in 2019 before Ruby goes on to become the Women's Champion herself.
