Unlike Surprise, the 2020 Shiner team is loaded with young talent and should remain competitive. However, there are opportunities for improvement. Most notably SP, RP, CF, C, and maybe RF. I'll list some potential trade bait below.
Batters: Raimel Tapia, Jose Peraza, Martin Maldonado, Billy Hamilton, Yairo Munoz, Franklin Barreto, and maybe Nomar Mazara
Pitchers: Ivan Nova, Jonathan Loasiga, Matt Strahm, Richard Rodriguez, Joe Ross, Andrew Miller, Yoshihisa Hirano, and CC Sabathia's final season!
I would also consider trading cash, picks, and/or prospects. However, just don't bother asking about Wander Franco or other elite prospects.
