I noted the Braves interest in Diaz when MLBTR first reported it early on this off-season, then again in January I passed on Jesse Sanchez report via twitter naming us among the teams interested. According to what I've read it seems the Braves interest in him is for the infield (second or third base). But the Cardinals and others seem very interested in him too. So I am not sure our chances at signing him. Also, Diaz apparently has a bit of a preference for short but is willing to move to another position.
BTW, we have also showed some interest in another Cuban player, catching prospect Yenier Bello. The Mets, Padres and others are in on him too.
