The Chicago White Sox filled out their 40-man roster Wednesday by claiming right-handed pitcher Raul Fernandez off waivers from the Colorado Rockies.
Team officials then assigned the 24-year-old reliever to Class A Winston-Salem.
Here's some background on Fernandez as provided by the White Sox:
• Fernandez was 0-1 with a 7.00 ERA (21 ER/27.0 IP), seven saves and 20 strikeouts in 29 relief appearances with Class A Modesto this season. He converted seven of his eight save opportunities.
• The 6-foot-2, 180-pound Fernandez spent the entire 2013 season with Class A Asheville, appearing in a career-high 35 games in relief and converting 16 saves, the third-most in the Colorado system. His best season came in 2010 with the Dominican Summer League Rockies, going 4-3 with a 1.52 ERA (11 ER/65.0 IP) and 46 strikeouts over 12 games (11 starts).
• A native of Boca Chica, Dominican Republic, Fernandez spent the 2008 season as a catcher before being converted to a pitcher full-time in 2009.
