WASHINGTON, April 13 (UPI) -- Jayson Werth singled in Danny Espinosa from third with one out in the 13th inning Friday, giving Washington a 2-1 victory over Cincinnati.
A dozen pitchers combined to give up 13 hits in the marathon, which ended with the Nationals winning their fourth in a row.
Washington tied it at 1-1 in the eighth on a homer by Xavier Nady and finally won it in the 13th after loading the bases against Sean Marshall (0-1).
Marshall came on for his first inning of work in the 13th and got the lead-off batter.
Espinosa, however, reached on an infield single, Ryan Zimmerman drew a walk and Adam LaRoche walked as well to fill the bases. Werth then hit a 1-2 pitch up the middle to produce the winning run.
Washington also won a 10-inning meeting with the Reds Thursday with Zimmerman scoring the decisive tally on a wild pitch.
The win went to Craig Stammen (1-0), who struck out the side in the top of the 13th as the sixth Washington pitcher.
