There was a trade Wallner, Trade Kiriloff, Trade Polanco.
What I would start off with is fire the hitting coach. That should have happened in the first half of the season.
Sign a right handed hitting first baseman with some pop in free agency. Those are a dime a dozen.
Figure out if Buxton can actually play the field but I feel like his knee problem/problems are chronic. You can't have a part time CF on the roster that can't make the DH adjustment(Some players just can't hit if they are not in the field). If he can't play the field because of his knee then try and get him to retire because this is just a wasted roster spot.
Bring back Michael A.
You have Pablo back so re-sign Gray or someone in that caliber. Honestly I would prefer Jordan Montgomery because we need a lefty in the rotation and he is also very durable.
Sign a lefty for the pen like Matt Moore.
I have been calling for Rocco's head for a while because I hate these 100% analytics guys but I will settle for a new hitting coach.
Take a flyer on Teoscar Hernandez as he is a right handed hitting outfielder with some pop. Yeah he strikes out a ton I know.
