WWE 13

Pretty simple stuff here, but for those who didn't play last year, here's a quick tutorial.

When you have a finisher stored up (as indicated by the F at your character's feet) take your opponent down and press up on the D-Pad to execute the wakeup taunt. They will get up slowly and be in a stunned state when they get to their feet. You must then get in position to do your finisher (this is the potentially tricky part as you need to know where your finisher triggers from. It's usually from the front, but some people have it in the back.) Press Y to hit the finisher, then as quickly as you can get back to them (if the finisher moves them away from you or vice versa) and press B to pin. If you win, the achievement will unlock. If not, work up the momentum and repeat this same process (but do not pin without doing the taunt AND the finisher first).

A fairly simple achievement to get, but the UKGamingBureau have done a video just for this achievement just incase you're still unsure on how to get it. Good luck and hope you get the achievement.
