Hagel has only played 26 games this year for the Iowa Wild, likely due to the Wild having too many vets and the vet exception rule. As mentioned by danielpalfredsson above, the Sens just moved out two AHL vets in Robinson and Stortini and likely wanted to fill that void somewhat. Kleindorst knows Hagel from his days with the Wild. Minnesota opens up a contract slot which might be a big deal, but they already had 2 slots anyways (Mike Russo believes this brings them down to 47 contracts).
