Good TDL moves, add solid pitching depth, Lorenzo has been both a starter and a setup man, so he can be a 6th starter, insurance against injury or Sanchez slipping, and provide BP depth for the playoffs. Lee is a solid prospect, but nothing special, I think Simmons emerging (who has more upside) made him expendable. And of course, Bergolla seems to be on a fast track.
Falter is no loss, at 26 he took a big step backward, with 2 top pitching prospects and Sanchez emerging, he's an afterthought in the organization. Castro gives them a potential RH bat who should be better than Harrison.
