How is Duffey going to prove that, if he isn't actually given a shot to prove it? I don't have high expectations for Duffey, but he did well last year and I'm not willing to toss that aside and yell "Fluke" without him getting a chance to prove it wrong. This team isn't a contender, the batters are young and too strikeout prone, the lineup isn't balanced or constructed well, the bullpen is still relying on middling vets and AAAA guys and the starters are spectacularly unreliable for guys who's most glowing praise is always "experienced veteran". Unless we want to continue pushing back the timeline because the young starters and relievers haven't had a chance to take their MLB lumps, they need to get called up this year and get considerable reps. I would rather watch Meyer, Berrios and Duffey lose 85 games than watch Nolasco, Hughes and Milone lose 80. And frankly, after watching the Twins young bats last year and the young players league-wide, I really see very little reason to expect the veterans to outperform the young arms.
