WWE Money in the Bank results: Liv Morgan wins MITB briefcase, cashes in and pins Ronda Rousey

Liv Morgan won the Money in the Bank briefcase, then cashed in on Ronda Rousey to become the new SmackDown women's champion. WWE

Theory lost his United States Championship to Bobby Lashley earlier in the night but left Money in the Bank with something far more valuable.

A surprise last-second eighth addition to the Men's Money in the Bank match, Theory capitalized by capturing the briefcase -- and a celebratory selfie -- in yet another signal he's earmarked for stardom.

Vince McMahon's protégé battled Riddle at the top of the ladder, eventually knocking him to the mat to secure the victory and guarantee himself a future WWE championship opportunity.

The match kicked off with Omos, standing 7-foot-3, imposing his superior size and strength on the competition. He cleaned house, using a ladder as a weapon. After an extended string of dominance, Drew McIntyre hit the Claymore on Omos, pushing him out of the ring. The fighter from Scotland was the first man to climb the ladder, but his progress was thwarted by Sheamus, who threw him off the ladder and outside the ropes. Sheamus and McIntyre then traded punches while Theory snuck up the ladder. In a comedic moment, they finally noticed and double-teamed Theory. They combined for 15 (not 10) Beats of the Bodhran.

Seth Rollins then took out both Sheamus and McIntyre with the ladder before he launched it at them. Rollins attempted a Pedigree on Riddle, but Riddle flipped Rollins onto a ladder, then connected with a Senton. Sami Zayn then asserted himself, using a drop-toe hold on Madcap Moss onto the ladder. Madcap responded with a stiff Irish Whip of Zayn onto the ladder before Riddle jumped into the fray. Riddle and Madcap fought at the top of the ladder under the briefcase before Omos interjected and Powerslammed Riddle. Omos then Chokeslammed Theory and began the climb up the ladder before he was stopped by McIntyre and Moss. They knocked Omos outside the ring with a Double Clothesline.

Sheamus and Riddle joined and attacked Omos with ladders. Finally, they all teamed up to bury Omos in a pile of about 10 ladders. While they were preoccupied with Omos, Rollins and Sami fought on top of the ladder inside the ring. Sheamus set up a second ladder next to them, before he tipped the pair over.

Moss pulled Theory off the ladder and hit a Fallaway Slam before he Powerbombed Zayn onto a ladder. Sheamus delivered White Noise on McIntyre, then connected on the Irish Curse Backbreaker on Riddle. He attempted a Brogue Kick, but Riddle avoided it and hit the Hangman DDT off the ladder -- rather than the ropes -- in an ode to his tag team partner, Randy Orton.

In one of the best spots of the match, Riddle then performed a Floating Bro off the top of ladder, taking out Sheamus, Rollins, Moss and McIntyre.

Omos, at long last, emerged from the rubble of ladders and again cleared out the ring. Riddle threw Omos into a Sleeper, but he quickly escaped. Theory began to climb the ladder, but Omos grabbed his throat with both hands and slammed him. Sheamus connected with the Brogue Kick on Omos, followed by a Helluva Kick from Zayn. Riddle threw Omos in the triangle, and Madcap tossed him over the top rope. Rollins then hit Omos with a Stomp on the apron, before they all teamed up for one of the high spots of the match. Rollins, McIntyre, Riddle, Zayn, Sheamus and Madcap performed a six-man toss of Omos through the announcer table, crumpling it.

Back in the ring, Zayn attempted to climb the ladder, but McIntyre stopped him before he connected on a Future Shock DDT on Sheamus. McIntyre set up the ladder and trapped Sheamus underneath. As he inched closer to the briefcase, Sheamus' faction member, Butch, interfered and locked McIntyre into a Sleeperhold as Drew continued to climb. Finally, Sheamus hit Drew with a knee while he was still in the sleeper before he then pinned McIntrye under the ladder.

Sheamus climbed and reached for the briefcase, but Drew powered out from under the ladder and hit Butch with a Claymore. McIntyre and Sheamus battled it out at the top of the ladder until Zayn tipped them over, sending them crashing into a nearby ladder laid across a turnbuckle. Zayn was able to touch the briefcase, but Moss stopped him. Then Rollins halted Moss with a Stomp.

Riddle set up a far taller ladder next to the one Rollins was climbing, and then began to fight at the top. Riddle then hit Rollins with a Super RKO off the top of the ladder. Riddle eventually recovered and climbed the ladder, only for Theory to emerge out of nowhere, throw Riddle off, and grab the briefcase to a chorus of boos.

What's next: Roman Reigns defends the WWE Undisputed championship vs. Brock Lesnar in a rematch at SummerSlam, and with it being a Last Man Standing match, the opportunity for a Theory cash-in appears ripe. Then again, Theory could hold the briefcase for months as he's built into one of the top stars on the roster.

Women's Money in the Bank ladder match: Liv Morgan def. Lacey Evans, Alexa Bliss, Raquel Rodriguez, Asuka, Shotzi and Becky Lynch

Liv Morgan def. Ronda Rousey (c) -- Briefcase cash-in for the Smackdown women's championship

Liv Morgan is Miss Money in the Bank.

In a fantastic, frenetic Women's Money in the Bank match, it was Morgan who climbed the ladder and captured the briefcase for a guaranteed shot at one of two women's championships (currently held by Ronda Rousey and Bianca Belair).

The action kicked into gear when Morgan and Becky Lynch attempted to double-Suplex Raquel Rodriguez -- before it was reversed. Both women were then Suplexed simultaneously onto the ladder.

Shotzi attempted to run up a ladder that was set up as a bridge to attack Rodriguez, but she fell through. With a pile of women now stacked on the ladder bridge, Lynch connected with a Springboard Splash onto all of them. Alexa Bliss then took out a group with a 450 Splash before she made the first climb up the ladder. Rodriguez stymied her climb before Bliss used a Hurricarana to throw Rodriguez into the ladder bridge.

Shotzi then absorbed a hip toss from Asuka onto that same ladder before she started another climb with Lacey Evans ascending on the other side. Becky tried to tip them over, but they caught themselves and landed on their feet. Evans was able to grab the briefcase, but she couldn't unhook it as Rodriguez was there to stop her.

Morgan then reached for the briefcase, but decided to go on the offensive and performed a Sunset Flip Powerbomb on Evans in one of the high spots of the match. That left Rodriguez alone atop the ladder, but Shotzi stopped her and threw her in a Tree of Woe on the ladder.

Shotzi then put Bliss onto her shoulders and connected with an Electric Chair Slam, with Bliss awkwardly crashing into the ladder back-first. Shotzi continued to push the pace and attempted a Senton off the top rope onto Lynch, but Lynch moved out of the way and Shotzi hit the ladder back-first.

Asuka returned to the mix and took out Lynch with a kick to the head. She climbed the ladder but Rodriguez threw her out of the ring. Rodriguez then set up the ladder as a bridge to the announcer table on the outside and attempted to send Asuka through the ladder. Instead Asuka countered and put Rodriguez into a triangle.

Lynch joined the action and set up Asuka flat on the ladder before she connected with a modified Senton before they both bounced off the ladder in another high spot that whipped the Las Vegas crowd into a frenzy.

With three ladders set up in the middle of the ring and the rest of the field climbing, Lynch tipped over Shotzi and Rodriguez off one ladder, then tipped Evans and Bliss off the other ladder before climbing herself. Morgan made her appearance to stop her ascent and set up another ladder next to Lynch's. Lynch tried to tip her ladder over, but Morgan stopped the fall by pushing off the top rope and took out Lynch. Morgan then grabbed the briefcase and cried tears of happiness as the Las Vegas crowd popped in a major way.

Ronda Rousey (c) def. Natalya

Ronda Rousey retained her Smackdown women's championship after she sunk in the armbar on Natalya in a back-and-forth match. Rousey attempted Piper's Pit early in the match but Natalya reversed it into a roll-up before she applied an armbar on Ronda. Rousey then reversed it into a Sharpshooter, Natalya's finishing move, before Natalya grabbed the rope to break the hold.

Rousey then went for the armbar, but Natalya pushed her through the ropes onto the floor, tweaking Rousey's knee. She threw Rousey into a Sharpshooter on the apron, but Rousey escaped by throwing Natalya into the turnbuckle.

Rousey attempted Piper's Pit again but her knee wasn't strong enough to execute the finisher, so she again went for the armbar. Natalya reversed it into a Sharpshooter, then Rousey revered into the ankle lock. Natalya again went for the Sharpshooter but this time Rousey reversed it into the armbar for the tap-out victory.

Liv Morgan def. Ronda Rousey (c) -- Briefcase cash-in for the Smackdown women's championship

With Ronda Rousey hobbled, Liv Morgan capitalized and cashed in her Money in the Bank briefcase she won earlier in the night. Morgan was immediately thrown into an ankle lock, but after an extended period in the hold as a victory for Rousey was teased, the challenger escaped and rolled up Ronda for the pinfall victory to capture the title.

What's next: Rousey hugged and congratulated an emotional Morgan after the match. It's possible the former UFC champion is set for a hiatus, which could set up Morgan against Charlotte Flair at SummerSlam.

WWE United States championship: Bobby Lashley def. Theory (c)

The reign of the youngest United States champion in history is over. A bloodied Bobby Lashley forced Theory to submit from the Hurt Lock to regain the U.S. championship.

Theory attempted the A-Town Down, but Lashley reversed the finisher into a roll-up. Theory then raked Lashley's eyes to escape a Powerslam before he hit Lashley with the All-Mighty's own finisher, the spear. Theory again went for the A-Town Down before Lashley countered and sunk in the Hurt Lock for the win.

The match kicked into high gear earlier when Theory went to work with a series of elbows, followed by an extended chin lock after a Superkick took Lashley off the top turnbuckle. After nearly two minutes, Lashley nearly powered out of the chin lock before Theory dug the lock in deeper for another 90 seconds or so.

Lashley finally escaped and connected on a serious of clotheslines and a belly-to-belly Suplex. Theory later attempted his somersault into a clothesline but was caught and Gorilla-pressed. Theory kicked out of a roll up, then used a drop toe hold to smash Lashley face-first off the turnbuckle. He finished that sequence with a somersault into a Shotgun Drop Kick.

Lashley then hit his Powerslam, which was the beginning of the end for Theory's first championship run.

What's next: It was a mild surprise that Lashley won considering the meteoric push Theory has enjoyed since he joined the main roster in October. However, Theory still looked strong in defeat. He was facing the most formidable opponent of his career, so a victory would have been yet another signal that Theory is earmarked for stardom. It's possible WWE wanted the belt off Theory so he could move onto even bigger things, but a rematch with Lashley could lie ahead, although a future match with John Cena was teased on Raw.

Undisputed WWE tag team championship: The Usos (c) def. The Street Profits

In an instant classic, The Usos retained the WWE unified tag team championship after they delivered the 1-D on Montez Ford following a double Superkick. The Usos and Street Profits were given ample time to deliver, with four false finishes that brought the crowd to its feet.

Angelo Dawkins and Montez Ford performed a double-team Suplex into a Frog Splash onto Jey Uso before Jimmy Uso later hit Dawkins with a Suicide Dive. The Usos then double-Suplexed Dawkins into the turnbuckle post on the outside. Finally, Dawkins was able to reach Ford for the hot tag. Ford attempted an attack from the top rope, but he was caught with a Superkick from Jey followed by a Drive-by from Jimmy on the outside.

The Usos then performed a double-team backbreaker into a flying Jimmy chop off the top rope, and then connected on a wishbone. Ford attempted a springboard attack, but Jimmy stopped him with a right uppercut. Ford finally grabbed the upper hand with a Suplex of Jimmy onto the apron on the outside before he found Dawkins for another hot tag.

That's when the match really kicked into high gear. Dawkins performed a somersault over the top rope that took out both Usos on the outside. Dawkins then delivered a Corkscrew Neckbreaker on Jimmy. Dawkins plowed through both Usos on the outside with a monster shoulder tackle before he later teamed up with Ford for a slam of Jimmy for the first false finish of the match.

In another false finish, Jey kicked out of the double Blockbuster. He traded punches with Dawkins before The Street Profits attempted a second double Blockbuster that was thwarted by Jimmy.

Ford absorbed a double Superkick but kicked out in a third false finish. He then dumped Jey over the top rope and hit both Usos with a flying splash on the outside where he cleared the turnbuckle in the high spot of the match. Ford finally connected on the Frog Splash on Jey, but Jimmy broke up the fourth false finish.

All four superstars began to trade blows in the center of the ring as the crowd went wild. Dawkins was taken out by being tossed into the timekeeper's area leaving Ford in the ring to take the pin. After the match was over, the highlight revealed that Ford's shoulder was up and as The Usos walked to the back, the Street Profits complained that the match should continue.

What's next: A Ford turn on Dawkins was teased as the High Flyer complained after viewing replays that his shoulder was actually up on the pin. It appears to be a matter of time until Ford turns heel and enjoys a singles run. Perhaps that will take place at SummerSlam when a rematch against The Usos seems likely.

WWE Raw women's championship: Bianca Belair (c) def. Carmella

In yet another successful defense of her Raw Women's championship, Bianca Belair defeated Carmella with the KOD. After the match, while Belair was celebrating the victory on the turnbuckle, Carmella attacked her and then followed with a series of punches, leaving the champion hurt and teasing a cash-in attempt. But Liv Morgan's music never hit.

What's next: This felt like a placeholder title match for Belair, who should find a new rival for SummerSlam.
