Lamb was designated for assignment by the White Sox on Wednesday.
EDGE Analysis
Lamb had sporadic playing time with the major-league club and had appeared in just two of the last six games. He slashed .212/.321/.389 with six homers, 20 runs and 13 RBI across 43 games in the big leagues this year but will now be cast off the 40-man roster to help make room for Romy Gonzalez, whose contract was selected Wednesday.
