Should the Orioles sign Renyel Pinto?

The Orioles, reports show, are interested in reliever Renyel Pinto. Pinto didn't pitch anywhere in 2011. In his major league career, he had a 2.1 WAR in 5 seasons, .42 WAR a season, which is worth $1.26 million a year. However, this is with a FIP over a run higher than his ERA as shown by his -.87 PE but an Adjusted PE of .24. His career FIP - is 109, and while he gets slightly more groundballs than flyballs, he has a career SIERA 4.46. He has really struggled with walks, walking nearly 6 hitters per 9 innings. His TR is actually about average at 8.41. I know the Orioles have had real pitching problems, but getting a pitcher who was average in the first place, and didn't pitch at all last year doesn't make a lot of sense.
