Here's how referee Mark Geiger explained his handball call on Adam Johansson tonight, and his non-call against Jhon Kennedy Hurtado earlier in the match:
"Adam Johansson's handling offense: The hand was in an unnatural playing position, and he was making himself bigger by taking space. His arms were outside of his body. [Jhon Kennedy] Hurtado's arm was next to his body, he was not making himself bigger, and this was a case of "ball-to-hand."
Sounders defender Jeff Parke also was asked what coaches teach defenders about keeping hands close to their bodies, and how referees usually call it:
"They say just to tuck your hands behind your back. but it’s difficult to defend when you’ve got your hand behind your back and you’re trying to move sideways. They say your arms can’t be outside your body, extended out. … I think there is a (gray area) sometimes. This ref … I’m just not going to say much about it. They (call Eddie Johnson offside early), but then at such a crucial time, the ref wants to change the game like that."
