If you want to spend the time, there are probably web sites that speak of "start"
who flopped, or repeatedly flopped in the post season.
I will give Wallner a break on this one.
Lewis played more than a handful of games in the Minors at 2 spots, SS and 3rd Base.
He is not playing Short Stop so his position will be 3 rd Base, the Twins are not going to make him flail away at a spot he a whopping whole 1 game in the Minors.
For a truly top pitcher, to replace Gray, you are going to have to offer Lewis, with Kepler and or Polanco and or one of our 4th or 5th starting pitchers.
Garbage in , garbage out does not work; been there, done that.
Well he still may sign, I will leave the doom and gloom IF we finally have try to find a pitcher of equal ability.
Remember we got Correa, so the Twins Org. must have some appeal.
