Chicago White Sox outfielder Carlos Quentin, on the disabled list since May 29, will begin a rehabilitation assignment at Triple-A Charlotte.

Quentin, who had 36 home runs and 100 RBIs last season in his first year with Chicago, has been sidelined with plantar fasciitis, a painful foot condition. He hasn't played since May 25.

Manager Ozzie Guillen said Friday that he hoped to get his slugging outfielder back shortly after the All-Star break, but was not certain.

Guillen said Quentin would be brought along slowly, playing three innings for Charlotte in his first game, then five innings the following game.
