Reliever Frank Francisco has elected free agency rather than accept his outright assignment from the White Sox, MLBTR has learned.

Francisco, 34, struggled in his limited time with Chicago this year. Through 3 2/3 innings, he allowed 5 earned runs on 7 hits (2 home runs) while striking out 5 and walking 3 batters. Francisco signed a minor league deal with the White Sox over the offseason.
