Disclosure: I'm a Timbers fan, but figured I would share with Perkins' new fans.
Since he joined the Timbers, Perkins made some great saves, but his distribution wasn't so great. However, he's really improved lately. I haven't had time to watch an Impact game with him in but he was making great strides as a Timber and I assume it's carrying over.
If you're interested, the post with the details is here.
