The Mariners have already made well on this trade with Domingo Santana leading the American League in RBIs with 27 going into April 25.
Ben Gamel is a role-player who, if he had stayed in Seattle, would have been platooning in left fielder facing right-handers. Meanwhile, Noah Zavolas was drafted last year by the Mariners in the 18th round. He probably would not be a member of the Mariners staff for at least two more years if he makes it at all.
Santana had a fantastic season in 2017 at the age of 24 years old.
