Denard Span scored from second on third baseman Jordan Pacheco's throwing error in the ninth inning, and the Washington Nationals stretched their winning streak to 10 games with a 1-0 victory over the Arizona Diamondbacks on Thursday.
Five of Washington's last six wins have come in its final at-bat of the game, and the streak is tied for the franchise record. Kansas City is the only other team to win 10 consecutive games this year.
Rafael Soriano (4-1) pitched a scoreless ninth for the Nationals, who swept three-game series against the New York Mets and Pittsburgh Pirates before winning all four games of this series.
Oliver Perez (2-3) got the loss for the Diamondbacks.
