But the Mariners do have a problem. They need to clear the way for a plethora of outfielders at some point, but still need youth and upside to stay on track for their 2021 contention goal. The simplest way could be to spend a little money in free agency but this runs its own risk.
The outfield free-agent class is weak and very few options have a good enough chance to retain or increase their trade value down the line. The free agents who may be able to do this will be expensive and will have other suitors with legitimate playoff aspirations for 2020.
