Twins have the bases loaded, the look on the Twins batter is one of pressure, and they act like they are really on the hotseat.
Twins pitchers load the bases, their look is of being under pressure and they strain to make the perfect pitch.
In other words, Twins look terrible on offense and on the mound, not making plays at the biggest moments of the game.
We can hope that this is just youth. Young players on the big stage in front of tens of thousands will naturally get a little amped up in those situations. For some, that might bring out their best; for others (especially Berrios, I think) it causes them to move away from the things that make them successful.
If this is still happening in a couple of years, we can call them chokers. For now, I'd rather just think of them as young and learning.
