There have been comments that Lewis is hurt, is he hurt or have the Twins told him to throttle it down so as not to risk injury. I saw him go first to third in the Cardinals series and he sure didn't look like he was having any issues. The Twins are notorious on being conservative with injured players and we never really know their true status.
Also Lewis even though he has been injured, he is a first overall pick and should be a cornerstone for this franchise. You need to give him a position and let him learn, get comfortable and coach him up. I thought they told him he was moving to 3B, let him play there and learn. If you want everyone in the lineup move Miranda to 2B if you are going to insist on playing Santana every day, even though he be a platoon player and defensive replacement at 1B.
This philosophy that you can play anyone anywhere only works so often, you wonder why we keep seeing sloppy play and plays not being made. This comes from players playing out of position and not learning from reps that are needed. Choose a starting 8 and if someone gets injured call up someone to replace that position. We have 3 utility players, 4 if you consider Farmer an utility player. That is way too many and makes your bench moves unproductive, because the moves are based who can play a position instead of what is our best move possible to get the most production out of the particular move.
