Smith signed a minor-league deal with the Mets on Wednesday, Tim Britton of The Athletic reports.
The 27-year-old was traded from the Rays to the Mariners ahead of the 2019 season, but he struggled after being sent west with a .612 OPS in 148 games before getting removed from the 40-man roster in September. Smith had a .773 OPS and 40 stolen bases in 2018 with Tampa Bay, and the Mets will take a low-risk flier in the event he's able to rediscover that form.
