The offense came alive, and starting pitcher Rich Harden turned in a good performance.
The Cubs entered the second half of the season 15th in runs scored in the National League, and that was a big reason for their lackluster 43-43 record at the All-Star break.
"We need to score more runs," manager Lou Piniella said. "We didn't score nearly enough runs in the first half."
The Cubs led the league in runs scored last year, and they also were first in walks, on-base percentage and slugging percentage. They've been no better than middle-of-the-pack in those key categories this year.
Harden snapped a two-game losing streak, during which he gave up a combined 11 runs. Harden's command has been off for much of this year, but he walked none while striking out seven Nationals on Thursday.
CUBS 6, NATIONALS 2: Harden worked six innings, giving up three hits and one unearned run. 1B Derrek Lee hit a solo homer in the third, and the Cubs added three runs in the ninth.
-- Harden continued to shine on the road. At home, Harden is 2-5 with a 7.59 ERA. After Thursday's victory, he is 4-1 with a 2.17 ERA away from Wrigley Field. Harden turned in the Cubs' 56th quality start of the season. That leads the major leagues.
--SS Ryan Theriot extended his hitting streak to nine games with a third-inning double Thursday. He also had a sacrifice fly in the Cubs' three-run ninth inning.
--RHP Carlos Zambrano's home run in the first game of Sunday's doubleheader was his third of this season and the 19th of his career. The switch-hitting Zambrano is the Cubs' all-time home run leader among pitchers. On the mound, Zambrano is 1-1 with a 1.86 ERA in three July starts.
--LHP B.J. Ryan, released by the Blue Jays last week, signed a minor league contract with the Cubs. He will pitch at the team's facility in Mesa, Ariz., before a likely assignment to Class AAA Iowa. In 25 appearances for Toronto this season, Ryan was 1-1 with two saves and a 6.53 ERA.
-- Lee doubled, homered and singled Thursday, and he showed no ill effects from the neck spasms that forced him out of a game last weekend. The homer was the 18th for Lee, who leads the team.
--LF Alfonso Soriano has batted sixth in six of his last nine games, including Thursday, when he went 1-for-3 with a walk. He was moved out of the leadoff spot July 4 and has batted sixth, fifth and third since then. He has not homered since June 7.
--3B Aramis Ramirez's five-game hitting streak was snapped. Ramirez came off the disabled list July 6 after spending nearly two months on the shelf with a dislocated left shoulder. He was 6-for-20 during the hitting streak. He has not homered since May 6, and the power may not return fully until the shoulder is close to 100 percent. Ramirez said he was about "85 percent" when he came off the disabled list.
