The White Sox have released outfielder John Mayberry Jr., the team’s Triple-A affiliate announced (Twitter link).

Mayberry had signed a minor league pact with the Sox back on Aug. 7, though his stay with the team’s Triple-A affiliate lasted just 13 games. In those 13 games, the 31-year-old was unable to correct the struggles he displayed earlier this season with the Mets, batting .162/.225/.189 in 40 plate appearances. Typically a potent weapon against left-handed pitching, Mayberry has slashed a combined .175/.246/.381 in 69 plate appearances versus southpaws in the Majors and minors. Throughout his big-league career, Mayberry has hit .260/.315/.517 against lefties.
