Poreda called up

The Chicago White Sox promoted rookie Aaron Poreda, according to multiple sources. Poreda, a big lefty, has dominated at Double-A Birmingham. Poreda just missed making the big league roster out of camp with Jose Contreras and Bartolo Colon taking the No. 4 and No. 5 rotation spots.

Fantasy Impact: You'd have to believe the White Sox called up Poreda to join the rotation, but does that mean the end of days for Bartolo Colon? Contreras dazzled Monday night against Detroit while Colon served up four gopher balls to the lowly Indians over the weekend. The Sox top three of Mark Buerhle, John Danks and Gavin Floyd is solid. Poreda would need to unseat Colon for a rotation spot. The Sporting News says the White Sox might go with a six-man rotation, but it's more likely that either Clayton Richard or Poreda ends up in the 'pen. Maybe both do for the time being and the Sox give Colon a couple more chances to start.
