The 2020 Seattle Mariners will begin the season without eight of the nine players who made up their Opening Day lineup in 2019. Seven of those players have either retired, moved on to other teams via free agency, or got traded, while one – Mitch Haniger – will miss the beginning of this stunted season due to a back injury. With a wide-ranging yet inexperienced pool to choose from, the Mariners have the luxury of trying on several different outfits before figuring out which one looks the best.
The only certainties for Opening Day, barring any unforeseen circumstances, are Kyle Seager at third base and Tom Murphy behind the plate.
