Marlins signed OF Joe Benson to a minor league contract. The agreement includes an invitation to spring training. The 25-year-old hasn't been in the majors since a 21-game stint with the Twins in 2011. Benson was a top-100 prospect before 2011 and 2012 but has struggled to hit for average at the minor league level. He'll have a shot to win a bench job with the Marlins this spring.
