The Dodgers completed a three-game sweep in this matchup of last-place teams with a 4-3 victory on Sunday. They did it without first baseman Nomar Garciaparra, who hasn't played since July 24 because of a strained ligament in his right knee and was placed on the 15-day DL before the game.
Cesar Izturis doubled home the go-ahead run in the eighth inning and the Los Angeles Dodgers hit three home runs against Ramon Ortiz.
James Loney doubled with one out in the eighth against Jon Rauch (3-2) and scored when Izturis grounded a 2-0 pitch up the first base line and off the glove of Nick Johnson on a backhanded attempt.
"I have to take the blame for this one because I didn't do my job in the eighth inning," manager Frank Robinson said. "If I'm going to pitch to Izturis, I've got to move Nick over towards the line a little bit -- or don't pitch to him."
The timely hits were a pleasant sight for manager Grady Little, who watched his team waste leadoff doubles four times in the first six innings.
"We got four doubles to lead innings off and didn't score, but Loney finally got a double for us at the right time," Little said. "We're proud of the way things have gone the past three days. That was an exceptional game in all ways."
Jonathan Broxton (2-0) pitched a scoreless inning for the victory. The right-hander retired pinch-hitter Daryle Ward on an inning-ending double play grounder with runners at the corners in the eighth.
Takashi Saito pitched a perfect ninth for his ninth save in as many attempts.
Andre Ethier and J.D. Drew homered for the Dodgers, who placed first baseman Nomar Garciaparra on the 15-day disabled list - retroactive to July 25 - because of a strained ligament in his right knee. Pinch-hitter Jose Cruz Jr. tied it in the seventh with a leadoff homer while batting for reliever Brett Tomko.
Mark Hendrickson allowed three runs, six hits and a career-high seven walks over six innings, remaining winless in six starts since joining the Dodgers in a trade with Tampa Bay on June 27. The left-hander, who was 4-8 in 13 starts with the Devil Rays, had never walked more than four batters in any of his previous 113 big league starts.
One of Hendrickson's three strikeouts came in the third, when he caught Damian Jackson looking after walking three straight batters with two out.
"That's not the way I pitch. That's totally uncharacteristic of me, to walk that many guys," Hendrickson said. "It was just one of those days where I was having trouble finding command of the strike zone. But I can feel proud that I made pitches when I had to and kept the team in it."
Third baseman Wilson Betemit made his Dodgers debut following Friday's trade with Atlanta, becoming the eighth player to start at third base for them this season and the 12th since Adrian Beltre left for free agency after the 2004 season. Betemit doubled twice and singles in his first three plate appearances.
"I know a lot of people here, I feel welcome here and I'm happy to be here," Betemit said. I was surprised about the trade because I never heard `Dodgers.' All I heard was the Yankees and the Padres."
Washington took a 3-2 lead in the fourth when Ortiz singled with one out and scored all the way from first on Lopez's double to left-center.
Ortiz allowed three runs, nine hits and three homers in 6 1/3 innings. On June 14, 2002, when he was with the Angels, the right-hander beat the Dodgers at Chavez Ravine with complete-game four-hitter -- all home runs.
The Nationals went ahead 2-0 in the second as Jackson singled home a run and Ryan Church scored on an embarrassing balk by Hendrickson. The 6-foot-9 former NBA player's back leg buckled as he tried to make a pitch to Ortiz, and he fell with the ball still in his hand.
"It was one of those things that happens," Hendrickson said. "My spike caught in the middle of the mound when I tried to stride out. It cost us a run, but what can you do? I just tried to regroup and do the best job I could."
Ortiz retired his first two batters in the third before Drew homered on the next pitch for his 11th of the season and second in three days. His grand slam on Friday night ended a personal home run drought of 168 at-bats spanning 42 games.
Ethier followed with his 10th homer, marking only the second time this season that the Dodgers homered back-to-back. Garciaparra and Drew did it on May 9 against Houston's Andy Pettitte in a 12-7 victory.
Nationals rookie LHP Mike O'Connor, who allowed a career-high seven runs and five walks over four-plus innings in Saturday's 7-5 loss while pitching with a sore elbow, was optioned to Triple-A New Orleans. The Nationals won't need a fifth starter again until Aug. 12. ... Washington C Brian Schneider left the game after three innings because of a mild strain in his lower back.
