The New York Yankees have signed David Aardsma to a one-year deal worth $500k, Joel Sherman of the New York Post reports. The deal includes a club option for 2013 as well.

Aardsma can also earn an additional $500k in incentives this season. However much he earns in incentives this season, that amount will be added to his base salary for next season which is also $500k.

Aardsma saved 69 games for the Mariners in 2009 and 2010 but was out all last season after Tommy John surgery in July.

In six seasons, Aardsma has gone 13-15 while posting a 4.20 ERA with 69 saves and a 9.1 k/9.
