I approve. IIRC the Nationals used the "hard innings" method on Strasburg the year he came back from TJ, instead of the look feel method, and their postseason ended in disappointment with their best pitcher watching from the bench (TJ is a little bit different beast, I admit). There's no hard inning limit, but you don't want to blow past that 20-30% bench mark with complete disregard, either. I assume the Twins would manage Berrios's innings so that he can pitch as late into the season as is needed. This is tricky, but in a good way!
