According to Roto World, Stephen Drew, Kendrys Morales and Ervin Santana may wait until after the June Draft to sign in order to increase their options. At that point, teams would not need to forfeit a pick to sign these players.
Roto World also admits this could be the work the agents, trying to drive up the pressure to get them signed now.
I can see how this could be an advantage to open up more teams to these players, especially if a team loses a player to injury between now and then, but this type of move is really done by players at the end of their careers, mainly pitchers, trying to cut down on the work load and bring in fresh legs (really arms) into the second half of the season. I don’t expect these three to do this because they are all just at their prime, and since most of them (Morales and Drew) are probably looking at 1 or 2 year deals, they need to put in work to get ready for the next off season.
We’ll see how this plays out. I think at least two of these players sign by the end of the week.
