The Rays picked up Luke Scott and Carlos Pena this winter to replace Johnny Damon and Casey Kotchman, and so far it's paying dividends. Although Scott is now hurt, both sluggers have had great starts to the 2012 season and have made immediate impacts in the lineup.
Fernando Rodney has also proven to be a smart addition to the roster, as he has excelled so far in the closer role for the Rays.
Jose Molina hasn't exactly got it going with the bat yet—although he is starting to hit a little better—but still bolsters the Rays' defense behind the plate. Jeff Keppinger is one more offseason acquisition that has paid off, as he's had some big hits during Opening Week.
