#4 Carmella
Carmella has always been a serviceable part of the SmackDown women's division, playing a decent mid-card figure. She has successfully found her place on the card and as a result, is a consistent presence in women's Royal Rumble matches.
The former Miss Money in the Bank entered the 2018 match with the briefcase, while her appearance in 2019 came from number 30, as she won the Mixed Match Challenge with R-Truth. Carmella had another average showing this year, entering at number 27.
#3 Natalya
The 'Queen of Harts' has had a growing influence on Royal Rumble matches over the years. Natalya's performance in 2018 was what you would expect from her, simply solid. She even eliminated 3 people, including her best friend, Beth Phoenix.
Natalya holds the record for the longest time spent in an all-female Rumble, at 56 minutes. She achieved the feat after entering from number 2 in 2019. And this year, Nattie entered at 23 and reached the final 4 before being eliminated by, you guessed it, Beth Phoenix.
