I am a believer that you need to go around the league twice to really know if a player's success is sustainable. At that point, they've seen the other team's adjustments to their approach - if you still are hitting at that point, time to move on. I didn't look it up but I assume the Lookouts have or will soon be twice around the league. If so, I move both to Rochester soon, for sure by the end of the month. Then, I give Vargas first crack at DHing with Arcia to follow if Vargas doesn't produce. If Arcia doesn't produce and the Twins still have something to play for, then Sano comes up to DH and play a little third.
