If you just look at the back of a baseball card, the Major League career of Rolando Arrojo looks like a one-year wonder.  That is true, but there is a lot more to digest with the Cuban defector.

An eighth round pick in 2007, Matt Moore was called up late in 2011 and was called up late in 2011.  He only played three Games for Tampa that regular season, he was on the post-season roster, winning a game in the playoffs. 

A Tampa Bay Ray for the first six seasons of his career, Jake McGee debuted in the Majors in 2010.  The southpaw only played eight Games for the parent club that year, but he managed to hurl more innings in 2011, and by 2012 he was a permanent player in the Rays bullpen.  From 2012 to 2014, McGee appeared in at least 69 Games, peaking with a 19 Save and 1.89 ERA year in 2014. 

In the up and down career of Fernando Rodney, the two seasons that the Dominican closer spent in Tampa Bay were mostly up.
