Flande was designated for assignment Saturday, Thomas Harding of MLB.com reports.
Jake McGee's return from the disabled list meant that the Rockies needed to clear a roster spot, and Flande's recent performance put him on the chopping block. After a clean outing against the Diamondbacks last weekend, things fell apart for Flande on Tuesday against the Blue Jays when he gave up a staggering five runs over just 2.2 innings of work. He'll now be subject to waivers and could benefit from joining a club that does not call Coors Field its home park.
