I think they would've if not for the timing, as I recall he was either struggling too in the minors or hurt around the same time (maybe a little of both at different points). Plus the only lefty he faced in the Majors he walked. Then he got out the righty after that and ended up getting a win in that game. If Buchter ever stops walking so many he could at least turn into a good lefty specialist for someone.
That said, I don't think Avilan has much of a future with us either. I am still thinking we'll probably trade him at some point.
