2012 first round MLS supplemental draft pick Eder Arreola is apparently going to be training with the Chivas USA reserves. He is a local kid who played 3 years at UCLA. As a UCLA fan I got to see him a few times against the bay area teams and in the college cup on TV. He is a winger with above average (but not blazing) speed but very good technical abilities - dribbling/passing/shooting/soccer brain. He can play left or right wing.
He was drafted by Houston and played very well in their preseason. I was keeping tabs on him and was pretty confident he would get offered a contract by them but they decided to go in a different direction. I was a little surprised that Kinnear drafted him b/c he is not a typical Kinnear winger (i.e. he doesn't have a ton of pace and is better in a more possession oriented system). FYI last season Coach Salcedo switched UCLA's tactics to be a full-on short passing possession-style system like Akron and Arreola did very well. I think he will fit in great in Fraser's system at Chivas USA.
He is not ready to start at the MLS level right now but he is a great prospect who can probably make some good contributions 1-2 years out if you give him some time to develop in the reserve league this year or on loan with a USL team. All in all a good return on investment in my opinion. It looks like Chivas USA only has 27 roster spots taken right now of the 30-man roster so there should definitely be space for him... and as a undrafted rookie he would not count towards the cap.
Here is a video of a sick left footed volley I saw him score against Santa Clara last season:
