FanGraphs on the 40 man moves:
More interesting than what Boston did Tuesday is what they didn’t do. They arguably had the biggest roster crunch in baseball, with nearly a dozen potential additions and eight or so current 40-man occupants who I’d consider on the roster bubble. Young righties Luis Perales (whose fastball has monstrous vertical carry) and Wikelman Gonzalez (plus secondary stuff) are both young and raw enough to expect they’ll spend their first year on the 40-man entirely in the minors. Prospects Grant Gambrell, Ryan Fernandez, Angel Bastardo, Chih-Jung Liu, Shane Drohan, Juan Daniel Encarnacion, Eddinson Paulino, and Allan Castro all had interesting cases to be added versus not. The relief-only guys (Gambrell, Fernandez) are lower-impact types who were probably safe to leave unprotected, Drohan’s rough second half hurt his chances of being rostered, and most of the rest of the candidates are extremely young and unlikely to stick on someone else’s active roster next spring. Especially as more and more teams tend to err on the side of not adding players this time of year, more and more players fill the potential Rule 5 Draft pool and the chance any one of your team’s guys gets popped in the draft drops through the sheer volume of alternatives. Liu (sitting 95 mph with a plus breaking ball and average split as a starter) could be vulnerable in the Rule 5, especially if teams think his stuff will tick up in relief.
