Covey stayed behind at the White Sox's training complex in Glendale (Ariz.) and threw 75 pitches, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Covey is building up endurance in preparation for an expected start Saturday. With news that Carlos Rodon (biceps) may not return until mid-May, Covey is in position to make five or six starts in place of Rodon. Of course it would take a bold fantasy player to activate a player with no experience above Double-A.
