What happened: The Arizona Diamondbacks close out their three-game weekend series against the Washington Nationals on Sunday at Chase Field. The Nationals are looking to complete a series sweep after taking the first two games.

Why it matters: A win would help stabilize the Diamondbacks, who enter the finale with a 33-31 record and sit 8.5 games behind the Dodgers in the NL West. Getting swept at home could stall their momentum as they try to keep pace in the division race.

What to watch: The Diamondbacks will try to salvage the final game of the homestand before turning their attention to their next matchup.
