Chicago, IL (SportsNetwork.com) - The Chicago White Sox have promoted top pitching prospect Carlos Rodon from Triple-A Charlotte.

Rodon will initially work out of Chicago's bullpen. The No. 3 overall pick in last year's amateur draft went 1-0 with a 3.60 ERA in two starts with the Knights this season.

The White Sox also activated pitcher Jake Petricka from the 15-day disabled list prior to Monday's game against Cleveland. The reliever had been out with a right forearm strain.

The 26-year-old Petricka went 1-6 with a 2.96 ERA and 14 saves in 67 appearances last year. He led all major league rookies in saves and ranked third in IP (73.0) and appearances.

Pitcher Javy Guerra was placed on the DL with right shoulder inflammation. The move is retroactive to April 13.

In addition, pitcher Kyle Drabek was designated for assignment.
