Petruzzelli has a 6-0 record this season with the Marlies posting a 2.31 goals-against average and a .922 save percentage. While it hasn't been ideal for the Leafs to sign him now, with the way he was playing, he was bound to get outside interest.
As Sheldon Keefe said yesterday, "Certainly, his signing is probably expedited given our situation, but he's a guy that our organization has believed in and, frankly, the way it was going his signing was somewhat inevitable."
Petruzzelli likely won't see much game action, possibly a start against Pittsburgh or Vancouver in the Leafs' back-to-back next weekend, but other than that it will likely be Kallgren's net until Murray, Samsonov or both return.
