Washington, DC (Sports Network) - Adam Dunn tallied the go-ahead, two-run single in the bottom of the sixth and the Washington Nationals held on to beat the Baltimore Orioles, 7-6, in the second installment of this interleague three-game series.
Josh Willingham homered and Cristian Guzman finished 3-for-4 with an RBI for the Nationals, who ended a two game skid. They had lost seven of eight games overall.
Craig Stammen gave up six runs -- four earned -- on nine hits in 5 1/3 innings. Tyler Walker (1-0) earned the win after finishing off the sixth inning and Matt Capps picked up his 16th save in as many chances.
"The feel of the game was there was tremendous energy in the dugout," said Nationals manager Jim Riggleman. "There were great attitudes going in the dugout, there was a will to win the ball game and the guys kept getting after it."
Ty Wigginton homered and drove in four runs, and Adam Jones hit an inside-the- park round-tripper for the Orioles, who have dropped three of four.
Brad Bergesen was knocked around for six runs on 11 hits in five-plus frames. Mark Hendrickson (1-2) was saddled with the loss after giving up Dunn's decisive hit.
"If you look at his fly-ball ground-ball ratio, it probably wasn't very good for a guy that's a sinker-ball pitcher," said Orioles manager Dave Trembley. "Obviously, that's got to tell you there wasn't a whole lot of finish on his pitches. But he competes, he battles, he had leads the entire ball game. We didn't make enough pitches and plays for it to happen."
Baltimore got on the board early, scoring two in the first. Nick Markakis and Miguel Tejada put together back-to-back one-out singles. Markakis advanced on the latter as Nyjer Morgan booted Tejada's single to right. Tejada then advanced to second on a wild pitch and scored along with Markakis on Wigginton's single to center.
Washington countered by loading the bases with two down in the bottom half, but Ivan Rodriguez flew out to center, ending the threat.
But the Nats tied the affair in the third on Willingham's two-out, two-run blast to left-center.
The O's took a two-run edge in the fourth. Luke Scott reached on an error from Stammen and moved to second on Wigginton's groundout. With two down, Jones drilled one high off the wall in center field. It took a bounce away from Morgan in center, who threw his glove down in digust after thinking the ball went over the fence, allowing both runners to score on Jones' inside the park homer for a 4-2 lead.
Washington got a run back in the fourth on Guzman's two-out single to left. Stammen scored on the play after doubling two batters before.
Wigginton drove in his third and fourth runs in the sixth with a one-out fences-clearer to left for a 6-3 Orioles advantage.
In the bottom of the frame, Roger Bernadina plated one with a triple to the right corner. The next batter, pinch-hitter Alberto Gonzalez, made it 6-5 with an RBI single up the middle. Ryan Zimmerman then reached on an infield single to load the bases as Dunn gave the Nats a lead with a two-run single through the middle off Hendrickson.
Baltimore didn't have a man on base the rest of the game.
The all-time series is tied at 13-13...Washington stranded 11 runners...Zimmerman finished 3-for-4...Tejada went 2-for-4....Rodriguez left the game with a lower back injury and is day-to-day.
