"I was very impressed with what took place today all over," Dodgers manager Grady Little said. "It takes a toll on you, but not really as bad if you lost both of these games."
In the opener, Bobby Abreu hit a three-run homer in the ninth inning in a 6-3 victory that stopped a season-opening four-game losing streak. The Phillies avoided their first 0-5 start since 1934.
In the second game, Penny (2-0) was in command throughout, striking out six and allowing only one runner to reach second base after the first inning. Penny also put the Dodgers ahead 2-1 in the fourth with a broken-bat bloop single off Jon Lieber (0-2).
Lance Carter completed a seven-hitter for Los Angeles, which had 15 hits.
Penny was at his best in the seventh after giving up a one-out single to Abraham Nunez. He fanned Sal Fasano, then struck out pinch-hitter Ryan Howard looking to end the inning.
"He stayed strong all the way through," Little said. "Probably the last pitch he made was the best one he made all game."
After rallying from a 3-0 deficit in the first game, the Phillies scored first in the second. Leadoff hitter Jimmy Rollins singled, stole second and came around on Abreu's one-out single. Abreu added an RBI double in the eighth, making him 4-for-6 with five RBI in the doubleheader.
Sandy Alomar Jr.'s RBI double in the second tied it for L.A. Former Phillie Ramon Martinez drove in two more runs with a double in the eighth, then scored on pinch-hitter Olmedo Saenz's double that made it 5-1.
"It was important for us to start pitching that way," Alomar said. "If I get a few knocks, that's great."
It also was great for the Dodgers for Penny to pitch deep into the game and settle down after a shaky first inning. With a quick turnaround that has the Dodgers playing Monday afternoon at Pittsburgh -- their third game in 24 hours -- Penny wanted to save the bullpen.
"I was just throwing strikes with all my pitches," he said. "I got a little more focused and made sure I was making pitches."
Lieber allowed two runs and struck out four in seven innings. Lieber is 1-7 in 12 career starts against the Dodgers, even though he's pitched at least six innings in seven consecutive starts against Los Angeles. He did lower his season ERA from 21.60 to 8.71.
"It was just a rough day," Lieber said. "Things snowballed."
