According to Patrick Newman of NBP Tracker, the Tokyo Yakult Swallows and Lastings Milledge agreed to a one-year contract with an option for 2013.
Milledge signed with White Sox on a minor league deal last winter and looked to be pitted against Alejandro De Aza and Brent Lillibridge for a backup outfielder role coming out of spring training. Milledge tore up the Cactus League and earned a spot on the team's opening day roster, but after two games and some shaky outfield defense in Kansas City, he was designated for assignment and accepted an assignment to Charlotte, where he spent the rest of 2011.
Given his success against left-handed pitching in previous seasons with Pittsburgh and Washington and his blue-chip pedigree, it's surprising Milledge didn't find a spot in the majors last season. The Sox didn't have any need for him with the emergence of Lillibridge and De Aza, but no team claimed him when he went through waivers just after his 26th birthday in early April. Maybe Milledge's defense is regarded so poorly that no team wanted to pick him up and risk an outfield blunder with him playing defense.
