The Mariners have firmed up their 40-man roster ahead of today’s 3 PM deadline to protect players from the Rule 5 draft, and opted to protect four players. This is a few more than we projected them to keep, but the additions aren’t surprising.
OF Taylor Trammell was an obvious choice to add; he’s a Top-100 prospect who was the primary target in the Austin Nola trade with San Diego and someone the Mariners are said to have been interested in for a while. An MLB-adjacent player with upper minors experience, TT was already a lock to be protected, but he added to his case with a strong performance both at the alternate site in Tacoma and in the fall development league, where he was somewhat unfairly unleashed against a crop of unsuspecting pitchers and lit up the box score seemingly every game.
