2021 Seattle Mariners Fantasy Baseball Rankings
#266 – Justus Sheffield – Left-handed pitcher (LHP) – SP
Justus Sheffield switched to a two-seam fastball in 2020, and it paid off well. The question for Sheffield is whether he’s ready to take the next logical step in his progression. If that happens, then Sheffield could be and stash player. One of many potential Mariner sleepers. He does have value in AL-only roto leagues, especially with ERA and possibly wins. The six-man rotation jeopardizes his usage in accumulative leagues.
Expected round to draft: Sleeper. He’s young. You should be able to draft him towards the tail end of your draft.
#248 – Jarred Kelenic – LH – OF
In dynasty formats, Jarred Kelenic is a top fifty pick. In 2021 rookie fantasy impact articles, he’s top five. The recent injury is a concern for when he’ll make his MLB debut, but as far as straight-up fantasy value for 2021, he’s a late-round stash-and-hope player.
There isn’t much value in his professional statistics, which will definitely raise questions about how effective he can be against major league pitching, especially with such a small sample size at AA in 2019. If Kelenic comes up and rakes, he’ll become a 5×5 star and likewise in accumulative leagues.
Expected draft position: NA. His draft position depends on the design of your league. In a dynasty league, he could go in the first four rounds. If it’s a traditional keeper league, then he could go in the first ten rounds. If it’s a yearly renew league, then consider him a sleeper.
#237 – Kyle Lewis – RH – OF
Kyle Lewis has tremendous upside, and while this lower ranking will come as a shock to some of you, for fantasy baseball diehards, this is exactly where he should be. The biggest thing for Lewis is which month is he more like from 2020? August or September. Mariners’ fans want it to be August and will settle for consistency. For roto leagues, Lewis’ value is his potential power.
Expected round to draft: 17. Lewis has value as a team’s fourth or fifth outfielder but not as a starter. Because of his age and experience, reaching for him can certainly be justified, maybe as early as the 12th round. Any earlier, and you will be called a homer.
