Santana (back) will test his back with a light throwing session Saturday, Mike Berardino of the St. Paul Pioneer Press reports.

Analysis:

There is no firm timetable for him to return, but it's good that he is scheduled to get some work in this weekend. The Twins are going with a youth movement for now in the rotation, as Jose Berrios, Tyler Duffey and Alex Meyer are all slated to be pitching every fifth day for the Twins going forward. However, once healthy, Santana figures to return at the head of the rotation.
