Re: Postseason roster?
No way should Alonso be on the post season roster. No matter how much talent he has and how good he might be some day, he's not ready for major league pitching yet. He currently can't hit an average major league fastball. Francisco or Valaika would be better choices than Yonder. ( I do wish him all the best though, and hope he'll be ready for a breakout season next year.)
