Waking up yesterday morning on May 18, I was taken aback to see that Lewis was sent back to AAA. Here are both viewpoints regarding the Twins sending down Royce Lewis, and then my own take.
Those in favor:
The Twins don't know how long Carlos Correa will be with the Twins, so they are sending Lewis down to continue developing at SS
In case Correa does stay for a while, it's necessary to find somewhere else in the field for Lewis to play, and AAA is the best place for him to
