What has happened in Twins Territory since March 29th?

Sorry I am asking this question, but I have been in Arizona since March 29th and I haven't been able to connect up.

I know that Alex Burnett made the team (not sure how); I know that Maloney and Grey (huh? how did this guy make it?) made the bullpen.

What was the Twins record since March 29th in ST? How are Scott Baker and Marquis doing? Who were the last cuts, both in the bullpen and the bench? Where is Waldrop on the "callup" list for the Twins?
