Players piled out of their dugout for a wild celebration near second base after Schumaker's pinch hit ended the Reds' longest slump since they dropped 11 in a row under manager Jack McKeon in 1998.
Cincinnati had the second-longest losing streak in the majors this season, trailing Colorado's 11-game slide from April 28 to May 13.
Brooks Brown (0-2) walked Marlon Byrd opening the ninth. Kristopher Negron's sacrificed, and Schumaker hit an opposite-field liner that landed just inside the left-field foul line. Jay Bruce led the charge of Reds players onto the field, and injured pitcher Johnny Cueto poured a bottle of water of Schumaker's head.
Aroldis Chapman (3-3), who had given up runs in each of his prior two appearances, escaped a two-on threat in the ninth by striking out Nolan Arenado.
