Notable Losses
After a few months of scouring the free agent and trade markets for a replacement for second baseman Jorge Polanco, the Mariners ended up signing….third baseman Jorge Polanco, brought back on a one-year deal worth $7.75MM in guaranteed money, and with a vesting option that could guarantee Polanco at least $6MM in 2026. Polanco has played the vast majority of his nine MLB seasons as a middle infielder, but he does have 24 games of experience as a third baseman, with 15 of those games coming as recently as the 2023 season when he was still a member of the Twins.
Polanco’s defensive metrics as a second baseman were mostly subpar, and his lack of a strong throwing arm raises questions about how well he’ll translate to the hot corner. However, the bigger issue might be whether or not Polanco can rebound from a rough year at the plate. The infielder hit only .213/.296/.355 over 469 plate appearances with Seattle in 2024, while also missing a month due to a hamstring strain, and undergoing surgery in October to correct a lingering left knee problem.
