Miguel Sano had a solid 2016, hitting .236/.319/.462 with 25, good for a 110 OPS+. He strikes out a ton–178 times to only 54 walks–but there is no denying the power. He is only 23, so there is lots of time for him to work on that aspect of his game.
For what it is worth, I really like the Twins. Even when they were contenders in the division a couple years ago, I could never really get myself to dislike them in the same way that I learned to hate the Tigers, Red Sox and Royals. I imagine that when they do become good again–which might not take too long–Sano will be a big part of that resurgence.
