Souza Jr. made the official announcement on his Twitter account. The 33-year-old veteran outfielder, who appeared in six games this season for Seattle, retires after logging eight years in the majors since 2014, including stops with the Nationals, Rays, Diamondbacks, Cubs, Dodgers and Mariners. He was drafted by Washington in the third round back in 2007. He finishes with a .229/.318/.411 triple-slash line with 72 homers and 42 stolen bases across 1,895 plate appearances in 505 games.

Souza was designated for assignment on Sunday and has now officially been cut loose. The veteran outfielder went just 3-for-19 (.158) with eight strikeouts during his short stay on Seattle's active major league roster.

Souza Jr. was waived to make space on the roster for Taylor Trammell. The 33-year-old veteran outfielder was just 3-for-19 with eight strikeouts with the Mariners. 

Souza Jr. gets the call back up the majors for the first time this season amidst the Mariners' flurry of activity Friday afternoon. The 33-year-old veteran outfielder was hitting .267/.417/.533 with five homers and three steals in 96 plate appearances this season at Triple-A Tacoma.
