I was watching a bit of Barrett Loux in a game on my computer tonight. I decided to round up some YouTube video.
This is the motion, largely, that I saw. He works quickly, usually pitches quickly, and represents a decent AAA option. His velocity doesn't blow you away, but he was getting people out by throwing strikes.
His feet aren't evenly planted on the rubber. His 'glove-foot' leads his 'throwing-foot'. And it is pronounced Loucks.
