Looks like this deal is technically not final, but:

Per mlbtraderumors, Twins have dealt Matt Garza, Jason Bartlett, and Eduardo Morlan to the Rays for Delmon Young, Brendon Harris, and Jason Pridie.

This will definitely have some ramifications for Johan Santana, but will probably just mean that the Twins want more MLB-ready pitching.

If they still trade Johan, mlbtraderumors suggests that this makes a deal with the Yanks, Red Sox, Mets, Mariners, and Cubs less likely, while he feels that Angels, Dodgers and Reds still have the pieces the Twins might want.
