Rey Mysterio recently made history by winning his latest match under the WWE banner. As seen at Sunday’s (May 19, 2019) WWE Money In The Bank pay-per-view event in Hartford, CT at the XL Center on the WWE Network, Mysterio beat Samoa Joe in a short match to win the United States Title.
This marks the first time that Mysterio has held the secondary title in his legendary pro wrestling career. As a result, he has been placed in the history books as Mysterio joins the ranks of WWE Grand Slam Champions.
The criteria of this are winning the top world title, a tag team title, and two secondary titles. Mysterio is a former WWE Champion and World Heavyweight Champion, 4-time WWE Tag Team Champion, and finally a 2-time Intercontinental Champion and United States Champion.
Post-match, Joe beat down Rey as Dominic looked on. Thus, with the beatdown after the match and the fact that each star holds a win over each other appears to be going in the direction of a third match happening.
