The Chicago White Sox have signed first baseman Dan Johnson to a minor league contract, according to Marc Topkin of the St. Petersburg Times. Johnson had previously been with the Tampa Bay Rays since being acquired by them in 2008. The 31-year-old is probably best known at this point for the epic ninth-inning, two-out, pinch-hit, game-tying home run that he hit against the New York Yankees to complete a stunning comeback that kept Tampa Bay's season alive. Otherwise, Johnson has hit .235/.334/.405 in 1520 plate appearances across six different seasons with the Rays and the Oakland Athletics
