In not very surprising news, the Yankees designated David Aardsma for assignment.
Via Andy McCullough of the Star-Ledger:
The Yankees designated David Aardsma for assignment. Team felt he couldn't provide distance in 'pen. "He didn't really fit," Girardi said.

Aardsma signed as a free agent with the Yankees in February 2012, as he was making his way back from a 2011 Tommy John surgery. He appeared in one game for the Yankees last year, giving up a home run, walking one and striking out one batter in one inning of work.
