Pena, who turned 35 last week, has not played a Major League game since he was a member of the D-backs and Mariners in 2011. However, he has remained somewhat relevant in the world of baseball, thanks to several excellent seasons -- and some tape-measure home runs -- in Japan's Nippon Professional Baseball Organization.
From 2012-15, Pena collected 71 homers and 222 RBIs with the Fukoka Softbank Hawks, Orix Buffaloes and Tohuku Rakuten Golden Eagles. He then took the 2016 NPB season off, before playing most recently in the winter league in his native Dominican Republic.
