Umm, well depends a lot of how you got to 50-40. If it is the All Star break Brinson/Hader are on the team. If they are making dreams come to fruition it is a mix of #1 and #3. I am not going all in, but I would definitely be trying low profile moves to bolster a hole/bullpen. At 50-40 it is a no brainer to try and compete to some extent. No way you are trading away any meaningful player especially if they are controllable. At that record you are probably holding a postseason spot. No management is trading away contributors while holding a postseason spot. Now if we are like 45-45 then I probably do little to nothing and if we have any players who are FAs after the season I would trade them if I get a good deal.
