In the Austin American-Statesman, Ricky Bennett explains the situation, what with Towles hitting .056:
"Each player is different. Obviously, a couple of years ago when we sent J.R. through the system, we did it rather quickly, and he didn't face a lot of adversity. That's not too much of a factor in how we move Jason."
Ricky Bennett, on Castro:
"Sometimes it gets lost that he's only had one full season of minor league baseball. A lot of transitioning was going on in his first year, and he just needs to continue getting the experience."
