I'd go all in for Bellinger. Adding an athletic, power-hitting centerfielder would make a huge difference this year. They could also really use a quality bullpen addition.
Would the Cubs go for Larnach or Wallner plus maybe our 3rd/4th best pitching prospect?
Admittedly I'm a Twins optimist, but I think with this pitching staff they can have an impact in the post-season.
