Of course, the Mariners best remaining trade piece left is Mitch Haniger. At 28-years-old (in 5 days) with 4 years of club control coming off a Top 10 MVP caliber, 6 win season, finding comps for a Haniger trade isn’t easy. Players like this rarely come on the market.
Thankfully for us, we don’t have to look that far back to find a comparison that works reasonably well for Haniger. In the winter of 2016, the Chicago White Sox shipped off then 27-year-old OF Adam Eaton off to the Washington Nationals. Eaton had 5-years of club control remaining, thanks to team friendly extension signed in 2015, but was also coming off a 6 win season, like Haniger.
