Although Truth was pretty confident about winning the match and the United States Championship, he was quickly eliminated by Tozawa, who then faced Ricochet. After a great back-and-forth matchup, Ricochet earned the pinfall by hitting the former Cruiserweight Championship with a Recoil. The next Superstar to enter the gauntlet was Matt Hardy.Mark it down:@RonKillings is taking the #USTitle and the #247Title ALL THE WAY to @WrestleMania! #RAW pic.twitter.com/auxo9Ya1FV— WWE Universe (@WWEUniverse) December 17, 2019Once again, Ricochet picked up the pinfall when he countered a Twist of Fate to a rollup. Humberto Carrillo was the next to join the fray. The two put on an incredible match and in the end, Carrillo got the win following a Moonsault. The final Superstar to enter the gauntlet was Andrade. Unlike the others, he took the fight outside the ring and knocked out Carrillo with a Hammerlock DDT on the concrete floor. With Humberto being unable to continue, Andrade was officially announced the winner of the gauntlet via WWE's latest Instagram post.
