Here are some roster realities. Haley is a Rule V, so he would have to be offered back to his original club if he's not on the 25-man roster. Santana, Adrianza, Grossman are all out of options. Vargas has another option remaining, as does Murphy. Park, Vogelsong, Schuck, Stubbs, Breslow (today) and Gimenez aren't on the 40-man roster and would have to be added in order to go north with the club. The 40-man is currently full, but Trevor May is a certainty to go on the 60-day DL and open a spot. The only veteran that I know of with an opt-out is Breslow, which is supposed to be resolved today (most likely added to the 40-man, with May on the 60-day DL).
