The White Sox claimed 25-year-old first baseman Lars Anderson from the Arizona Diamondbacks.
Anderson, rated as the Red Sox' No. 1 prospect in 2009, had one hit in eight at-bats with Boston last season. At AAA Pawtucket he batted .259 with nine home runs and 52 RBI. Anderson was traded to Cleveland on July 31 and finished the season with Class AAA Columbus.
In 30 career games over three major-league seasons with Boston, Anderson is 8-for-48 (.167) with four RBI.
Anderson was sent to Arizona in a five-player trade in December and designated for assignment on Jan. 24.
The Sox have a need for a left-handed bat but are set at first base with Paul Konerko and left-handed hitting Adam Dunn. The Sox 40-man roster is now full.
