I would define "limited sellers" as one of the following: Quintana, Severino, or Manaea. And I might be coaxed into including Bader.Next 10 games are against Nats, Rockies, Marlins. 6 of the 10 at home. In my opinion if after that stretch you're still piddling around with win one, lose one, win two, lose three and are still latching onto a record that's .500 or 1 game under or one game over then you need to consider being limited sellers. Not gonna have a better chance than this of getting to a record 4-5 games over .500 like the the last 2 teams currently in wild card position.
If you are making Alonso available, then you've gone beyond just limited.
