Indians signed RHP David Aardsma to a minor league contract with an invitation to spring training. Aardsma has an uphill battle on his hands to win a roster spot, barring injury, as he'll have to beat out Bryan Shaw or Vinnie Pestano for a bullpen job. Aardsma posted a 4.31 ERA and 1.46 WHIP over 43 appearances for the Mets last year. He hasn't been effective since he was a 28-year-old pitching for the Mariners in 2010.
