Plouffe was designated for assignment by the Athletics on Thursday, Jane Lee of MLB.com reports.
No surprise here, as the Athletics opted to cast the struggling veteran off the 40-man roster in order to bring top prospect Matt Chapman up to the big leagues. Plouffe only batted .214 this season, although he's not too far removed from some quality big-league innings, so it wouldn't be too surprising to see him land another MLB job relatively soon.
