"The Orioles continue to add to their crowded 40-man roster.

The club has signed reliever Luis Ayala, a 34-year-old right-hander who had a resurgent 2011 when he was 2-2 with a 2.09 ERA in 52 games with the New York Yankees, to a one-year, major league contract. The deal is worth a guaranteed $925,000. There is a team option for 2013 for $1 million with a $100,000 buyout.

Ayala will earn $825,000 in 2012, and there are performance bonuses, mainly based on appearances, worth up to $350,000 for both 2012 and 2013."
