Chris Cotillo of MLB Daily Dish reports that six to seven teams are interested in free agent reliever Matt Thornton. Cotillo hears that the Nationals are one of them. Thorton, 37, is coming off a 3.74 ERA and 30/15 K/BB ratio over 47 1/3 innings this past season between the White Sox and Red Sox. He's not the dominant reliever he once was, but should still be useful in 2014.
