Lee broke a streak of 126 at-bats without a home run with a three-run shot in the second inning to help the Chicago Cubs complete a three-game sweep of the Houston Astros with a 7-6 win on Sunday.
The Cubs have won 15 of their past 19 games and swept the Astros in a three-game series at Wrigley Field for the first time since May 1984.
The Cubs fought back from a five-run deficit in the second inning.
"We're playing with confidence, regardless. ... We never felt we were out of the game," Lee said. "We knew we had a good team, but now we have that confidence to go along with it. There was a time where we got down like that we might not of been sure that we could come back."
"The club is gaining confidence and that's the important thing," Cubs manager Lou Piniella said. "They're playing with confidence and confidence is a good thing."
The Cubs used five relievers to preserve the victory, who combined for five scoreless innings.
Mike Lamb homered for the Astros, who have lost six straight on the road.
Astros starter Wandy Rodriguez (6-8) couldn't hold an early 5-0 lead. He allowed six runs on seven hits in the second inning. With one out, Mark DeRosa doubled and scored on Geovany Soto's single. On the next pitch, Pagan hit a two-run homer. It was his fourth of the season. Jason Marquis and Theriot followed with back-to-back singles. Then with two outs, Lee hit a three-run home run into the left-field bleachers, giving the Cubs a 6-5 lead. It was his seventh of the season, his first since June 3 against the Braves.
"It's been a long time," Lee said. "It felt good, plus it gave us the lead and put us back in the game, so it felt very good."
Rodriguez was coming off an impressive four-hit shutout of the New York Mets on July 6, but left after 3 1/3 innings. The lefty gave up seven runs and nine hits in his shortest outing of the season.
"He got in situations where he didn't use his breaking ball or couldn't use his breaking ball, and they hit his fastball," Astros manager Phil Garner said.
Marquis, who started for the Cubs, didn't last long. Lamb tied the game with a solo shot in the third inning off Marquis. It was Lamb's eighth of the season.
Theriot's leadoff homer in the fourth inning broke a 6-6 tie. It was Theriot's second of the season.
Marquis went four innings and gave up six runs on six hits. Marquis' ERA in his past seven starts is 6.75.
The Astros threatened in the seventh inning, they had runners on first and second with no outs. Luke Scott drove a ball to the warning track, but DeRosa made a nice over-the-shoulder catch. With runners on second and third with one out, Cubs reliever Will Ohman got Brad Ausmus to line out to third. Then Wuertz came in and walked pinch-hitter Morgan Ensberg to load the bases but ended the inning by striking out Chris Burke.
"That's a great play out there with the (basket) hanging out over the field," Piniella said.
The Astros added four runs off Marquis in the second inning. Marquis gave up a leadoff single to Lamb and Scott drove in Lamb with a double. Ausmus followed with an RBI single. After a sacrifice bunt by Rodriguez, Marquis walked Burke. Then with two outs and the count full, Berkman doubled to center, scoring Ausmus and Burke, giving the Astros a 5-0 lead.
"All I ask is we hit the ball hard and we did today. We had good at-bats when we had opportunities to drive somebody in, and we hit the ball hard and we didn't get anything for it," Garner said.
- Before the second inning, Rodriguez pitched 17 consecutive scoreless innings.
- Piniella dropped Alfonso Soriano to fifth in the batting order from the leadoff spot, hoping it would lead to more offense against lefty starters.
