White Sox call up top prospect Carlos Rodon, activate Jake Petricka from the disabled list

The White Sox have promoted their top prospect to the big leagues. Left-hander Carlos Rodon will be available to work out of the bullpen Monday night when the South Siders take on the Cleveland Indians at U.S. Cellular Field.

The Sox also have activated relief pitcher Jake Petricka (forearm) from the disabled list. To make room for Rodon and Petricka, relief pitcher Javy Guerra was placed on the 15-day disabled list (retroactive to April 13) with shoulder inflammation, and relief pitcher Kyle Drabek was designated for assignment.

Rodon's early call-up is a bit of a surprise. He made only two starts in Triple-A Charlotte. The first was a good one, as he struck out nine and allowed only a run on two hits in five innings against Norfolk on April 11. His second outing was just average, three runs on six hits with four strikeouts in five innings against Gwinnett on April 16.

The Sox had indicated a preference to have him work as a starter, presumably because he might eventually be called up to take the place of one of the Sox's two middling starters -- John Danks and Hector Noesi -- later in the season.

But apparently, the Sox have changed course and decided to let Rodon get his feet wet at the big-league level by using him as a reliever. It's the same philosophy they used with Mark Buehrle and Chris Sale in previous years.

Some have speculated the Sox are bringing Rodon up to try to give a slow-starting 4-7 team a jolt, but let's hope he's actually being called up because he's ready for the opportunity. I would suspect that's the case. I can't believe the Sox would rush Rodon to the big leagues for public relations reasons. The organization makes some questionable moves, but there is no way they are that stupid.

Petricka, who had 14 saves for the 2014 Sox, fired a scoreless inning in each of his two rehab outings at Triple-A Charlotte. He figures to give manager Robin Ventura another option in the seventh or eighth inning moving forward.

Guerra is unscored upon in three appearances for the Sox this season, but he's worked only 1.2 innings. Perhaps the shoulder issue was a reason for his scarce workload to this point in the year.

Drabek has not distinguished himself in three outings this season, allowing three runs on nine hits over 5.1 innings. If he clears waivers and reports to Charlotte, that's nice, but if another team does claim him, the Sox have other pitchers in their organization who can do what he does.
