Adam Morrissey

I've been meaning to ask about A's farmhand Adam Morrissey for a while. Today, he was removed from the 40-man roster to make room for Tim Harikkala, making the question a little more timely. I already know why he isn't considered much of a prospect: he's an infielder whose defense seems to be awful, and his bat isn't quite good enough to be moved elsewhere. But even given this, the organization seems a bit too eager to give up on him: first by relegating him to the bench early in the season in Sacramento, even though the team is full of older players who are also non-prospects, and now by designating him for assignment. He's still fairly young (not yet 24, and repeating AAA). So is there something I'm missing here, or does Morrissey still have some chance of being a major league player?
