FYI Luhnow is on Astroline right now. I just got it to work, he was talking about how much they like Feliz but they need roster flexibility, he's not close to the majors, and he doesn't think another club will be able to keep him on their 25-man all season.
Bottom line (my impression) is it's not about Feliz vs. Krauss or whoever, but Feliz vs. some other player that will need to be added in the next year because they need him on the Major League roster. Even if Feliz makes it from Lancaster to Corpus by the end of 2015, he's still a longshot to contribute in the majors before 2017; meanwhile, they'll have to burn an option year on him, and be restricted by having less space on the 40-man for shuttling guys from AAA to MLB. If he doesn't stick with another team all year, they get him back, and don't have to add him until a year from now.
Okay, Jeff, but... if you're wrong...
