Miguel Amaya hit an RBI single in the eighth inning — only the second hit for Chicago — and four Cubs pitchers combined for a one-hitter in a 1-0 victory over the Cleveland Guardians on Sunday in the opener of a traditional doubleheader. Amaya's hard shot to right-center field off Connor Brogdon (2-1) scored pinch-runner Dylan Carlson from second base. The Guardians managed only one hit — a double that possibly could have been caught — against Cubs starter Edward Cabrera (5 2/3 innings) and relievers Caleb Thielbar (1-0), Hoby Milner and Daniel Palencia, who worked a perfect ninth for his first save.
