The Mariners designated him for assignment last Wednesday to make room on their 40-man roster for first baseman Adam Lind, who was acquired in a trade with the Brewers.
Wilkins played 17 games for the White Sox in 2014, batting .140 in 43 at-bats. He hit .251 with 18 home runs and 79 RBIs in 126 games in Triple-A last year in the Dodgers' and Blue Jays' organizations.
