Reigns continues with clotheslines on Joe and then a big kick! Reigns is sizing up Joe, but Joe moves out of the ring... Joe looks dazed. Reigns hits a Superman Punch on Joe on the outside.

Reigns get into the act as he hits big right hands onto Strowman... Now the match moves towards the crowd and Reigns drives Strowmans head on the barricades... before Strowman returns it...

Strowman gets a big forearm on Joe and then puts both his competitors onto turnbuckles of either side and clotheslines them; he then throws them outside the ring and shouts 'this is my yard'... We wonder what Reigns thinks of Strowman stealing his little line...

The three giants size each other up as RAW's triple threat match is to get underway. Remember, triple threat rules mean that there won't be any disqualifications or count outs.

Finn Balor's music hits, the lights dim out, and Balor is right behind him!

Wyatt was expecting him down the ramp and laughs hysterically and shouts 'I like it very much'. Balor takes the fight to Wyatt with a baseball slide and then puts him over the barricade!

... and more things that we - at least - can't comprehend very clearly. More laughing ensues... and now he's on the floor laughing like a ... erm... lunatic.

Bray Wyatt begins his weekly monologue on RAW. Calls the Pittsburgh crowd 'pitiful', and derides the 'Balor Club'.
