The word was too good to keep to themselves yesterday, but the White Sox made it official today: Carlos Rodon is on the 25-man roster. If all goes according to plan, he won't be leaving it for a while.
The Sox purchased Rodon's contract from Charlotte, the headliner of four announced roster moves. They also answered a question we didn't try to answer: After wearing No. 80 in spring training and No. 41 at Charlotte, Rodon will make his MLB debut wearing No. 55.
*Jake Petricka is back from the disabled list after completing his rehab stint for a sore forearm in Charlotte. He pitched twice for the Knights, throwing a scoreless appearance in each outing.
*Kyle Drabek was designated for assignment, to the surprise of nobody. Drabek bounced back from an awful debut, but didn't show much to distinguish himself even during better innings. If he clears waivers and goes to Charlotte, that's cool. If he doesn't, the Sox have comparable pitchers serving as Triple-A depth.
*Javy Guerra was placed on the 15-day disabled list retroactive to April 13 with right shoulder inflammation. Guerra might be one of those conveniently timed DL stints, but given that he's only recorded five outs on the season, his noticeably light workload provides some cover.
