Guillen appears to be on his way to one of those Billy Ashley/ Ruben Rivera kind of careers: unlimited potential but limited results to show for it. He was released between the 1999 and 2000 seasons. In the sequence of trades surrounding Guillen and the Zingrods in recent seasons, however, the end result is that the Zingrods got Manny Ramirez for Mark Loretta, so his tenure wasn't a total loss.
