Yoán Moncada hit a three-run homer, Touki Toussaint pitched five scoreless innings and the Chicago White Sox beat the Oakland Athletics 6-2, finishing a difficult week for the franchise with a sorely needed victory. Lenyn Sosa and Andrew Benintendi also homered for the White Sox, who had dropped four of five. Approaching the end of a disappointing season, Chicago fired executive vice president Ken Williams and general manager Rick Hahn on Tuesday. Then two women were injured Friday night in a shooting that occurred during the Athletics’ 12-4 victory at Guaranteed Rate Field.
