I originally thought that there might have to be a trade or two made this week before the deadline for adding minor leaguers to the 40-man roster. I thought we might need to clear roster space. But, now, the roster stands at 37 and there are at least two guys we can take off with no heartburn (Lewis and Aardsma). That would open five spots - enough for 5/7ths of: Pie, Nolasco, Marshall, Marmol, Ryu, Sing, and Brownlie. After that, though, there will have to be some 2- or 3-for-1 trades made, because there's going to be a roster crunch when we start adding new core players.
