The Cubs have designated 23-year old righty reliever Lendy Castillo for assignment. Castillo pitched in 13 games (0 starts) in his first taste of the majors for the Cubs last year and was 0-1 with a 7.88 ERA and a 2.25 WHIP. He also pitched in 7 games (all starts) in Rookie+A+AA-ball last year for the Cubs in which he was 0-0 with a 0.90 ERA and a 0.95 WHIP. The Cubs hope that Castillo clears waivers as they likely want to keep him around.
UPDATE: (2/6/2013) - Lendy Castillo has cleared waivers and he has been outrighted to AAA-ball by the Cubs.
