Grading Sox Young Pitchers

De La Rosa. Workman. Webster. Ranaudo. Do you throw a blanket over these 4 & pick one to be the 5th starter next year. All have been good at times. All have been bad at times. ERA's are around 4.50, but that's not uncommon for young arms finding their way. De La Rosa & Webster have swing & miss stuff. Ranaudo & Workman pitch to contact. Early returns is that Workman may be better suited to the bullpen, like Matt Barnes. Ranaudo pitched a good game last night in an 11-3 win. But De La Rosa & Webster have had some success as well. It may come down to what other teams think about these 4 pitchers & whoever doesn't get moved in a trade. To me the 5th spot is between De La Rosa, Webster & Ranaudo. What do you think?
