WWE Universal Championship: Brock Lesnar (c)  def. Roman Reigns, Samoa Joe & Braun Strowman by pinfall

Lesnar started the fight off strong, throwing a german suplex at Reigns, then Joe. Joe and Reigns jumped back into the ring before Lesnar could attempt the suplex to the Monster Among Men. After getting tossed outside of the ring by Strowman, Lesnar got caught in a Coquina Clutch by Joe before Reigns speared the champ through the barricade.

Strowman cleared out both competitors, then picked up Lesnar and drove him through the announce table. Strowman then threw a chair at Joe and Reigns and put Lesnar through another announce table. He picked up the final table and simply dumped it on Lesnar. Unreal.

Paramedics were called down to ringside, as they put Lesnar on a backboard to cart him out of the match.

Strowman picked up right where he left off, picking up the stairs and going after Joe, then Reigns and eventually Joe again. Back in the ring, Reigns hit Strowman with the stairs three times and Joe entered the fray, rolling up the former champ for a two-count. After all three guys were laid out, Lesnar made his triumphant return from the back.

He took out Strowman, german suplexed Reigns, then gave one to Joe for good measure. Reigns went on a Superman Punch spree, hitting all three guys before landing the spear to Lesnar for the two-count. Strowman hit the running powerslam on Joe and Lesnar pulled the referee out of the ring before he could count to three.

Joe locked in the Coquina Clutch, which was reversed into the F-5, where he got a two-count before Reigns broke it up. Reigns hit three Superman Punches on Lesnar and Lesnar reversed a spear attempt into the F-5 for the win.

WWE Championship: Jinder Mahal (c) def. Shinsuke Nakamura

Nakamura brought Strong Style to Mahal, stomping Mahal around the ring. Mahal turned the tide, working Nakamura's head with elbows and a chin lock. Nakamura got his comeback going with a couple of well-timed knee strikes and he reversed a powerbomb attempt into a triangle choke. Mahal got his legs under the bottom rope in time to escape unscathed.

Both Singh brothers jumped into the ring as Nakamura set up for the Kinsasha. Nakamura took both brothers out before Mahal hit the Khallas out of nowhere to defeat the unbeaten (on the main roster) Nakamura.

United States Championship: AJ Styles (c) def. Kevin Owens (w/ special guest referee Shane McMahon) by pinfall

Shane-o-Mac was all over the place in this one, getting caught in the crossfire over and again. He was pushed into the ropes to knock Styles off the top rope, was checking on Owens when Styles hit a 450 splash on both of them and got knocked out of the ring as Owens tapped out to the calf crusher.

Styles got in his face for missing the tap and McMahon pushed Styles into a rollup attempt by Owens, who got the quick two-count. Styles missed a Pele kick and got caught with a super kick. Owens set him up for the pop-up powerbomb, but Styles reversed into the Styles Clash for the two-count. Owens connected on the pop-up powerbomb, but Styles got his foot on the rope as McMahon counted three. He quickly reversed the call to a two-count.

McMahon pushed Owens into the rollup for the two-count. Styles hit the Pele kick, the Phenomenal Forearm and another Styles Clash for the three-count.

Raw Tag Team Championship: Seth Rollins and Dean Ambrose def. Cesaro and Sheamus (c) by pinfall

Ambrose and Rollins started hot, but Cesaro and Sheamus gained control on the outside, catching a diving Rollins and throwing him. Sheamus then turned his attention and hit the Brogue Kick on Ambrose, knocking him out on the outside.

Cesaro held Ambrose in the sharpshooter. As he got close to the rope, Cesaro flipped it around into a crossface, but Ambrose reversed into a two-count. Rollins got back into the action with an insane frankensteiner on Cesaro, connected on the knee strike to Sheamus and Ambrose hit the Dirty Deeds for the pinfall.

Demon Balor def. Bray Wyatt by pinfall

Wyatt hit a suplex on Balor from inside the ring to the outside mats. Balor recovered and beat Wyatt around the ring, connecting on a dropkick into the barricade.

Wyatt worked over Balor in the ring and did his creepy back bridge in the ring. That lit a fire under Balor, who lept to his feet, hit the slingblade and connected on the Coup de Grace for the win.

Raw Women's Championship: Sasha Banks def. Alexa Bliss (c) by submission

Bliss attacked Banks' shoulder early, punishing the former NXT star around the ring in a brutal corner spot before eventually tossing her outside of the ring.

Bliss connected on the Twisted Bliss for the two count.

Banks made her comeback, turning over into the Banks Statement, but Bliss reversed into a two-count. Banks then turned her over into the Banks Statement again for the submission.

Randy Orton def. Rusev by pinfall

This one didn't last long — Rusev missed a clothesline into the corner and Orton hit the RKO for the win.

Big Cass def. Big Show (w/ Enzo Amore locked in a shark cage) by pinfall

Amore oiled himself up and exited the cage, but it wasn't enough to help Show. Cass hit a big boot on Enzo, a big boot on Show and an Empire Elbow to beat the 7-footer.

Smackdown Women's Championship: Natalya def. Naomi (c) by submission

Naomi's entrance still remains amazing. She started the bout off with a brutal looking blockbuster on the outside.

The champ appeared to injure her right leg on the apron early on. Natalya worked the knee and reversed a submission attempt into the sharpshooter. Naomi rolled backwards, throwing Natalya into bottom turnbuckle. Natalya got her knees up to block Naomi's split-legged moonsault, and locked in the sharpshooter to notch the win.

John Cena def. Baron Corbin by pinfall

Corbin got the hot start before Cena's typical comeback attempt. Corbin stopped him in his tracks, connecting on a brutal looking chokeslam backbreaker:

Cena looked for the AA, Corbin reversed into the Deep Six for a two count. Cena recovered enough for the AA for the three count and if there was any doubt Corbin is in WWE's doghouse, this should be crystal clear as he takes another clean loss for the second time in five nights.

This one was action-packed, with Woods showing off an arsenal of moves he usually doesn't get the time to. New Day seemed to have the match in the bag more than once before the Usos eventually took advantage, tossing Woods over the top rope and rolling him back in to hit the double top rope splash for the win.

Just six nights before SummerSlam, Tozawa pinned Neville to become the Cruiserweight champion.
