The Blue Jays designated Fleming for assignment Tuesday.
Toronto will continue to churn the final spot in its bullpen, as Fleming was dropped from the 40-man roster just one day after long reliever Austin Voth was DFA'd to clear a spot for him. The veteran lefty was unlikely to be available for at least a couple of days after he worked in long relief in his Blue Jays debut during Monday's 14-2 loss to the Dodgers, covering three innings while yielding four earned runs on six hits and two walks.
