Geraldo Perdomo’s fielder’s choice erased Marte at the plate, but Carroll moved to third. Nolan Arenado struck out to end the inning with no runs scoring initially. However, the Diamondbacks broke through in the eighth. Gabriel Moreno singled and advanced to second on a sacrifice bunt that first baseman Josh Naylor misplayed for an error.

In the top of the 10th, Arizona put a runner on third with one out after a sacrifice bunt moved Ildemaro Vargas to third. But Luis Castillo induced a groundout and a strikeout to escape. In the bottom half, Seattle’s Victor Robles delivered the decisive hit. With the bases loaded after an intentional walk and a sacrifice bunt, Robles singled to shortstop, scoring pinch-runner Randy Arozarena for the walk-off win.
