Awful, just goddamn awful from Mr. Coffin. Straight into my top-10 list of most terrible performances ever since I started to watch tennis.
I cannot see any excuse for this toilet performance. Even simple shots ended up in UEs. Jarkko didn't really have to do anything but just put the ball back in play and sooner or later (usually: asap), the ball would end up in the net or somewhere miles behind the lines.
I'll just try and pretend this match never happened.
