The A's bullpen was a major strength in 2018, but it likely will look a bit different next season.
Veteran right-handers Jeurys Familia, Cory Gearrin and Fernando Rodney are unlikely to return, and Shawn Kelley is uncertain on his future.
The good news is that All-Star closer Blake Treinen should be back in green and gold, along with Lou Trivino, J.B. Wendelken, Ryan Buchter and Yusmeiro Petit. That still leaves a few openings for Oakland to fill, potentially in free agency.
Since they already have their closer and back-end setup men, the A's don't need to make a huge splash, but they certainly could use another veteran arm or two.
