"As the Twins enter at least a soft rebuild, it will make more sense for these four roster spots to go to younger pitchers with more upside. The Twins will almost certainly need to convert some starters to relievers this offseason, as they have a glut of pitchers presumably fighting for just a couple of rotation spots, with more prospect depth on the way."
I generally agree with this, although they are going to have to bring in at least a couple guys with some track record to fill out the bullpen. Given their financial constraints, they will have to target guys like Justin Topa, which makes their decision to decline his option somewhat odd. Is the ill will created by going through arbitration really worth the few nickles they might save?
