The White Sox released Chavez on Saturday, Bob Nightengale of USA Today reports.
The White Sox signed Chavez to a minor-league contract Feb. 8 and invited the right-hander to compete for a bullpen spot in spring training. The 31-year-old struggled over his seven innings pitched as he allowed nine runs on 12 hits and two walks while striking out eight. Chavez will weigh his options in free agency.
