Wells, 28, has had quite a ride this season. He began the season with Seattle before being claimed off waivers by Toronto on April 10. He was then designated for assignment by the Blue Jays on April 15 and traded to the A's seven days later. He was 0-for-5 in three games for the A's before being designated for assignment on Sunday.
Wells, a right-handed hitter, began his career with the Tigers and owns a .244/.314/.431 career slash line with 25 home runs in 227 games.
