Right-hander Reynaldo Lopez (0-1, 13.50) will pitch for the White Sox. Duffy last pitched on Friday, going five innings and allowing one run during a 7-2 win. Also on Friday, MLB celebrates Jackie Robinson Day as teams across the league will wear No. 42 patches to honor Robinson. The date, Aug. 28, honors the day in 1945 when Dodgers president Branch Rickey sat down with Robinson in Rickey’s Brooklyn office in hopes of signing MLB’s first Black player.
