A few years ago I attempted to predict the Great Lakes Loons opening day roster. It proved to be a very difficult assignment as there are so many variables at play. First, it seems impossible to know which young players may have suffered spring training injuries, perhaps minor, or experienced other delays but it does mean they are not on the opening day 25-man roster as expected. A second variable is how quickly the Dodgers front office wants to move players along. I think it is a relatively safe bet that the current front office believes in moving players along as quickly as reasonable while taking extra precautions with pitchers, especially those who have rehabbed from Tommy John surgery.
