Williamson was optioned to Triple-A Tacoma on Thursday.

Analysis
Williamson had been the Mariners third baseman prior to the Eugenio Suarez acquisition, and it makes more sense for Williamson to be playing every day at Triple-A than playing sparingly in the majors. Known more for his glove than his bat, Williamson is slashing .253/.294/.310 with one home run and five steals in 85 games as a rookie.
