Especially bad considering that the initial reasoning behind waiving Volpatti was to accommodate bringing Pinizzotto off of the IR (who was then immediately sent down for a conditioning stint).
Pinner was only really on the roster on paper and only for a day. Could have easily made room for this by doing a paper demotion of a non-waiver eligible player with an immediate recall, subsequent to Pinizzotto being demoted (haven't read the new CBA yet but I'm assuming a couple of the young guys wouldn't go through waivers under 2013 rules). Clear the space to move Pinizzotto off IR and down for conditioning without risking the waiver loss of a roster player.
So, even without the Kesler situation, Volpatti appears to have been needlessly exposed.
That all said, I'm pretty OK with swapping Sestito for Volpatti. Like most people, I liked Peppermint and like to have players with local connections but, strictly in terms of roster strength, this is most likely a net gain (albeit marginal).
