After clearing waivers, the White Sox sent veteran right-handed pitcher Jose Contreras to the minor leagues to work out his difficulty with his command.
According to sources close to the situation, Contreras was the one who suggested that he goes to the minors instead of being relegated to the bullpen.
In the meantime, the Sox have called up left-handed pitcher Jimmy Gobble from Class AAA Charlotte to plug into the bullpen. Left-handed pitcher Clayton Richard will start Tuesday night's game in Cleveland and become the temporary replacement for Contreras.
Contreras had to clear waivers, which meant all 29 teams had 48 hours to claim him and his $8 million-plus contract that remains from the original $11 million deal.
Contreras will work on his split-fingered pitch, which he has not been able to command, in particular against left-handed hitters this season.
