I see a lot of these players on a regular basis up close and in person, which probably causes some attachment.
There is always a little sense of loss with certain players when they get traded away, regardless of the % of them that actually make it to the MLB level.
Barrios was a great player here, super fan friendly, and always looked like he was having fun with his teammates. With how few guys hit in the 300's these days, it was a joy to watch his hitting approach, and I thought that he was one who is probably going to do great things after leaving Appleton.
