Wuertz, 34, has not pitched in the big leagues since notching 33⅔ less than stellar innings with the Oakland Athletics in 2011.
The right-hander was released by the A's following the season and was not picked up by another club until May of 2012, when the Reds took a flyer on him. Wuertz was battling injuries, however, and did not get the chance to throw even one inning before Cincinnati let him go the next month.
That the Marlins are willing to give Wuertz a full-fledged deal complete with an invitation to camp gives the indication that the right-hander's injury problems are behind him.
At one point a dominant set-up man, Wuertz owns a career 3.71 ERA, 4.3 BB/9 rate and 9.6 K/9 rate in parts of eight big-league seasons with the Chicago Cubs and the A's.
