The Mariners optioned Trammell to Triple-A Tacoma on Tuesday.
Trammell broke camp with the big club in 2021, but after turning in a .160/.256/.359 slash line with a 42.1 percent strikeout rate across 178 plate appearances in multiple stints with Seattle, he didn't see any action with the Mariners after mid-July. Though his production at Tacoma was much better (.818 OPS, 22.9 K% in 323 plate appearances), he didn't mash at a level that made him a strong candidate to earn a spot on the Opening Day roster this time around. Trammell will thus return to Tacoma to begin the 2022 campaign, and his odds of getting an extended look in the majors will likely dim further once the Mariners are ready to give top prospect Julio Rodriguez a look in the big leagues.
