Nationals signed LHP Sean West to a minor league contract. West hasn't appeared in the majors since 2010. He had a 5.59 ERA in 87 innings last year at the Triple-A level.

Marlins sent LHP Sean West outright to Triple-A New Orleans. West is off the 40-man roster after clearing waivers, which speaks volumes about how much his stock as dropped since being selected as a supplemental first-round pick in 2005. The 25-year-old southpaw posted an ugly 5.59 ERA and 56/46 K/BB ratio over 87 innings at the Triple-A level last year and underwent offseason elbow surgery.
