Of course there are many ways to say it. I’m just putting mine. Can it be wrong? Yes it can! Will people will understand what I’m saying? They probably will. So here’s my shot.

Written world:

The Brazilian [tennis] player was impaired by the chair umpire’s decision.
Don’t underestimate Federer’s capacity of reaction.

Spoken world:

The umpire’s decision messed up with the Brazilian.
Fedrerer has skills to react.

Talking with my Friends

This umpire is fucking up with the Brazilian dude…
Don’t mess with Federer he’ll kick your butt.

I hope it helps....
