Federowicz was released by the Dodgers in September after batting .200/.291/.371 with three home runs in 25 games (79 plate appearances) at Triple-A Oklahoma City. "After 14 years playing the game that I love, I have decided to call it a career," the 34-year-old catcher wrote on social media Tuesday. "As for what’s next, I have recently accepted a role to become the AAA manager for the Tacoma Rainiers. I am very excited about this opportunity and can’t wait to get started." He replaces Kristopher Negron, who was named first base coach of the Mariners this offseason. 

Federowicz hasn't appeared in the majors since 2019. The 34-year-old veteran backstop served as organizational catching depth for the Dodgers, hitting .200/.291/.371 with three homers across 25 games at Triple-A Oklahoma City this season.

Federowicz broke the news himself on his personal Twitter account. The veteran catcher is a career .192/.241/.328 hitter at the major league level and will probably be somewhere around third or fourth on the Dodgers' organizational depth chart behind Will Smith, Austin Barnes, and top prospect Keibert Ruiz. 

Federowicz appeared in 29 major-league games in 2019, hitting .160/.213/.347 with four home runs and seven RBI. The catcher will likely begin the season with Triple-A Nashville, although he'll get the chance to work out of the big-league camp during spring training.
