I think this is the big kicker here, and probably the biggest reason that I like this trade. I feel like every year, I see comments about how the Twins failed to sell high on a prospect. Just in the last year alone, I can think of Gonsalves, Romero, and Gordon (each of whom could have gotten a pretty decent return if they had been traded 2-3 years ago). If Graterol had stayed with the team, what would have happened to his value if he had gotten injured or if it became obvious to the Twins and the rest of the league that his long-term home was in the bullpen? His value would have plummeted. Is it possible that we will regret trading him and his value will actually continue to increase? Absolutely. However, I would rather trade him now, when his prospect value is still relatively high, than regret waiting too long.
