I'll go ahead and say my final needs:
(1): A pitcher that can start Game 1 or 2 of a playoff series. I prefer Ryan, but not sure if the Twins will trade him. I love the Cabrera/Alcantara combo because of stuff. I wouldn't mind Keller either, but not sure if Cubs would want to trade Caissie in division.
(2): Suarez: I would trade for Suarez even if Shaw is red hot as of late. It lengthens the lineup, and improve the bench, and it'll keep teams like Milwaukee and Philadelphia away from getting Suarez.
(3): Bullpen. I'll go after another difference maker like Classe or Duran. But, if the Cubs don't want them, then I'll go after a specific lefty that can get guys like Harper/Schwarber and Ohtani/Freeman out in October.
(4): Another batter that can come off the bench and produce. Not sure who that'll be, but the bench needs to get better.
If we can get two of those options, I'll be thrilled. Doubt we will get 3 of those 4.
