Health concerns are completely separate from this argument about service time. No matter the situation in Minnesota, if Ryan feels Berrios is hitting a wall, he has to shut him down. Period. At some point, the Twins need to stop worrying about 2022 at the expense of 2015. Like I said, if it's April 1st, yeah, you play Jose in Rochester for 3-4 weeks and then call him up to grab that extra service year because "why not?" But every. win. matters. right now. If Berrios can fill a role and help the Twins squeak out even one more win without bringing up any long-term concerns about his arm, you make that move because one win could be the difference between making the playoffs or missing by a game. And, again, the Twins can send Berrios back down if he struggles in 2016, getting back that extra service year. The vast majority of Twins prospects bounce back and forth a few times before sticking in Minnesota. I hope Berrios isn't one of those guys but I wouldn't bet against it. On top of all that, don't you think Berrios will benefit from learning what it feels like to compete against the best talent in the world in crucial situations during a playoff run?
