Austin Theory Shocks John Cena with WrestleMania 39 Upset Win

Austin Theory defeats John Cena in the opening match of WrestleMania 39 to retain his United States Championship title, using a low blow and his finishing move to secure the win. Cena had made a grand entrance with a crowd of Make-A-Wish children, but Theory, who idolized Cena, managed to crawl out of an STF and take advantage of a knocked-out referee to score the upset victory. Cena's willingness to pass the torch to Theory is seen as a boost for the young wrestler's career.
