Gregory Santos has been the Chicago White Sox’s most effective reliever. Recently moved into the closer role, he retired all five batters he faced on 16 pitches for the save in Tuesday’s 5-3 win against the Cubs in the City Series at Wrigley Field. Santos again got the call in the ninth Wednesday. “Things didn’t go my way,” he said through an interpreter. Christopher Morel hit a walk-off, three-run homer as the Cubs beat the Sox 4-3 in front of 40,869. “He’s been unbelievable for us all year long,” Sox first baseman Gavin Sheets said.
