Providing results in bracket tree

Hi brothers in arms!
Today I'm testing the bracket tree flow for our PGS League app. Here is a small interaction to provide score after match in tournament bracket. By clicking on pair you are inputing results in forms for each player. And after clicking an ENTER button the winner is moving to the next stage. So what are you suggestions about usage: easy or not?

P.S. I did that project in Sketch + Animate CC
