#5 Bayley
Bayley won her maiden SmackDown Women’s Championship at the Money in the Bank show of 2019. She had earned the Money in the Bank contract earlier in the night before she chose to cash it in on Charlotte Flair who was celebrating her Championship win over Becky Lynch.
The former RAW Women’s Champion then established herself as the face of the SmackDown Women’s division with fights against Alexa Bliss, Ember Moon, and Charlotte Flair.
While her feuds with Bliss and Moon were short, she had good title matches against the two female Superstars. WWE did not pull the trigger on either of the feuds because their intention was to turn Bayley heel when Sasha Banks would return.
Their strategy succeeded as the NXT graduate turned heel on an episode of RAW following Banks' return. She then retained her Championship in a heelish manner against Charlotte at Clash of Champions before losing it to her at the Hell in a Cell show.
Since the Fox era kicked off during the reign of Bayley, this rank has been awarded on the basis of her work till the end of the SmackDown Live era.
