Contrary to what it may seem, the Seattle Mariners are a mess at first base.
Justin Smoak was supposed to be Seattle's first baseman of the future, but has been wildly inconsistent, even getting demoted to Triple-A for stints in each of the past two seasons. The relegations have helped, but he hasn't made great strides in his offensive game.
Dustin Ackley can play first, but may need to share time at second base or in the outfield next season, depending on who Seattle can sign in free agency. He's also been disappointing and may be better suited for a utility role until further notice.
First round pick D.J. Peterson will probably eventually be making the transition from third to first, but is in Single-A and won't be seen in Seattle for at least another season or two.
Kendrys Morales is the ideal first baseman for the Mariners, although he was mostly a DH. He's already said he won't accept Seattle's qualifying offer, but that doesn't mean Morales won't play for the Mariners next season. He'll be tough to bring back, considering the limited power on the market, but his familiarity with the club and the organization could help Jack Zduriencik's chances of bringing him back, or hurt them depending on their relationship.
Based on their career-long body of work and estimated salaries, here are free agent first basemen the Mariners should target this winter.
