The White Sox traded Dunn to the Rays on Tuesday in exchange for Joe Rock.
Dunn doesn't own a 40-man roster spot, though he may soon receive one from the Rays after slashing .296/.397/.533 with eight homers, 33 RBI 31 runs scored and nine steals through 40 games at Triple-A Charlotte. Until then, he'll fill in as organizational infield depth at Durham.
