According to La Velle, the Twins have traded Jeff Cirillo to the Diamondbacks for a minor-leaguer, whose identity is unknown at this time. (Update: La Velle is now reporting that the D-Backs actually claimed Cirillo off waivers, meaning that the Twins will get nothing in return.)
Why? Beats me. They needed to clear a spot on the roster for Michael Cuddyer's return from the DL, but Cirillo is certainly more valuable than, say, Luis Rodriguez.
