CLEVELAND (Interstat) — Miguel Amaya’s eighth-inning RBI single broke a scoreless tie and lifted the Chicago Cubs to a 1-0 victory over the Cleveland Guardians in the first game of a day-night doubleheader Sunday at Progressive Field.

The game was a tense pitchers’ duel. Cubs starter Edward Cabrera allowed one hit over 5 2/3 innings, while Cleveland’s Slade Cecconi yielded one hit over six scoreless frames. The Cubs managed only two hits total, with Amaya’s line drive scoring Dylan Carlson against reliever Connor Brogdon (2-1).

Caleb Thielbar (1-0) earned the win with 1 1/3 innings of relief. Daniel Palencia pitched a perfect ninth for his first save. The Cubs evened their record at 4-4, while the Guardians fell to 5-4.
