Pyatt is a UFA at the end of the season and has a cap hit of $1.55 million.
The Rangers, according to Cap Geek, after losing Pyatt have $2.669 million in cap space.
The Rangers play the Penguins tomorrow night.
Adam Rotter: The most important thing about Pyatt being claimed is that all of his salary comes off the books for the Rangers. Had he been sent to Hartford the Rangers would have had $625,000 in dead cap space.
