#2 Becky Lynch became the first superstar to lose a major title match but win the Royal Rumble on the same night.

Yes. In the 31 year history of Royal Rumble, no other superstar managed to win the Royal Rumble match after losing a title match on the same night. Two years ago, Roman Reigns entered the Royal Rumble match as the number 30 entrant after losing to Kevin Owens in the Universal Championship match. However, the big dog felt short of winning the Rumble after Randy Orton countered a spear with an RKO and eliminated him.
After losing to Asuka in the opening match of the night, Becky Lynch's participation in the rumble was in doubts. However, due to an 'injured' Lana being unable to compete in the Rumble, Becky took her place and made full use of the opportunity.
Lynch created history by eliminating Charlotte to win the second ever women's Royal Rumble.Only a handful of superstars who had a marquee match at Royal Rumble actually took part in the Royal Rumble match. But other than Becky Lynch, none of them could win the Royal Rumble.
