Sellers. Regroup for 2018. Sign 2 SP this offseason. Hope and pray at least one of Heaney and Richards/Skaggs can come back and be a #3 type SP. Build the bullpen around Bedrosian/Parker by adding 2-3 more quality arms there. Get a left fielder and 2B that can hit their weight.
Players that should be traded before July 31st for whatever you can get (assuming we are out of the race like I think we will be): Espinosa, Revere, Maybin, Cron/Marte (one of them), Escobar, Chavez, Nolasco. Those players aren't bringing back anything significant, but maybe you get back a guy or two that can contribute to a team that actually has a chance to be successful. Injuries killed that chance this year, as much as it sucks to say that on May 7th
