WWE 2K22

Easy enough.

Select Randy Orton as your superstar, charge up your finisher, throw your opponent against the ropes as his coming back press LB, as the opponent goes up in the air, RT + A for your finisher.

Alternative method. I tried using the irish whip / LB / finisher method but was never getting the prompt to hit the finisher. If you're having the same issue, this is how I got it:

Whip an opponent into any corner, press up on the right thumbstick to sit him on the top turnbuckle, then stand anywhere within driving range and wait for him to awake. When he does, he'll do a jumping attack where you can catch him with the RKO as long as you have a saved up finisher stock.

"Catch finisher" flashes for a split second. It's the same RT + A button press. If you happen to miss the timing, just repeat the process above of seating your opponent on the top turnbuckle until you catch him.

Very easy way to do this

Go to the Creations tab and click on Custom Matches.

Choose one on one, iron man (to give yourself more attempts), accept it all until the 4th setting. Move “FINISHERS” over to 3 so you automatically have 3 finishers ready for the match. Save the custom match.

Choose Randy Orton and Jeff Hardy. Play as Randy and let Hardy get to the top ropes then keep holding down the trigger and pressing A.

This can be hard, but I found it easy to let Hardy attack you until you are on the ground. He will go for the top rope most of the time. You need ti make sure you are standing though, so it may take a few attempts. It took me 2 too ropes to get it.
