There is no rush to make trades right now.
Rizzo should be in a rush. This is the worst pen in baseball. Three months later, it isn't getting better. If you gave us an average pen, such as the White Sox, Rockies, Diamondbacks, or Royals, this team is 4 games up on the first WC and is probably within 4 games of Atlanta.
This team doesn't even need a ton of back end of the bullpen help. It simply needs decent middle relief. Guys like Andrew Chafin, Adrian Houser, or Seth Lugo. None of these should cost a ton.
