#4 Ronda Rousey vs. Sasha Banks (Royal Rumble)
Ronda Rousey requested this match for a reason because it gave her best singles match to date. Rousey looked like a gritty, determined, and nasty champion in ways she hadn't before (which will serve her well during her coming feud with Becky Lynch). Sasha Banks, for her part, revived some of her old Boss persona, much to the delight of the audience.
Sasha Banks' technical wizardry kept Ronda Rousey guessing through some of the matches, and the use of pieces of her attire during an application of the Banks Statement put the match over as an even nastier one.
Eventually, banged up hand and all, Ronda Rousey put Sasha Banks away with an armbar, and thus passed another important test. Ronda Rousey showed she could carry weaker workers like Nia Jax and Alexa Bliss, but would she be able to keep up with the better workers on the roster, like Sasha Banks? The answer was an emphatic yes.
