LOS ANGELES -- Anybody who has followed the Dodgers this season must have been confused as to who exactly suited up as Los Angeles' starter in Game 2 of the National League Championship Series.

It sure didn't look like Chad Billingsley, the blossoming ace who went 12-3 the last three and a half months of the season, ranked seventh in the NL with a 3.14 ERA -- 0.05 behind Game 5 counterpart Cole Hamels -- and beat both of Arizona's co-aces, Dan Haren and Brandon Webb, in crucial contests that swung the division's momentum in Los Angeles' favor down the stretch.

Billingsley punctuated that stellar season by yielding just one run on five hits in 6 2/3 innings, while striking out seven to just one walk, in a Game 2 win in the National League Division Series at Wrigley Field in which the 24-year-old right-hander was proving that he could pitch on a national stage.

But then came Game 2 of the NL Championship Series at Philadelphia.

Billingsley threw the worst game of his career, giving up a career-high eight runs -- seven earned -- on eight hits in 2 1/3 innings, with three walks and five strikeouts. He twice allowed four-run innings without the aid of a home run, and 10 of 12 batters reached base before he was mercifully pulled.

Now with the Dodgers trailing the Phillies, 3-1, following Monday's Game 4 loss, Billingsley has a chance to atone for that outing.

"I think after the last outing and how disappointed he was, whether this outing was pitching 2-2 or down 3-1, he was knowing how pivotal it was going to be," said Dodgers manager Joe Torre.

Added catcher Russell Martin, "I'm sure he wants another shot at it."

For the Dodgers to keep their reservations for a Thursday afternoon flight to Philly, Torre said the young right-hander needs to do a better job of working both sides of the plate and changing speeds than he did in Game 2.

"I think the last time out he may have tried to over-prepare," Torre said. "[It] looked like he was trying to do too many things or think about doing too many things, as opposed to just going out there and staying with his plan of using his stuff and changing speeds and the variety that he has."

The eight runs were as many as he had given up in his final six regular-season appearances combined besides a shelling of seven runs (six earned) in 4 2/3 innings Sept. 17 at Pittsburgh. That outing would have been much cleaner if not for a grand slam he yielded to Adam LaRoche on his final pitch.

Going back further, Billingsley yielded three runs or fewer in 18 of his previous 20 starts dating back to July 17, during which time he was the Dodgers' most consistent pitcher.

He's been particularly good at Dodger Stadium, going 6-0 with a 1.65 ERA over his past seven home starts.

"We have confidence in him," said Dodgers first baseman James Loney. "He just left a few balls up last time, but his stuff's been great."

It's been a rough week for Billingsley. After his Game 2 start, some veteran teammates chirped they were not happy that nobody retaliated after Phillies Game 2 starter Brett Myers threw under the chin of Martin and over the head of slugger Manny Ramirez.

After the game, Billingsley said pitches intended to back Pat Burrell and Jayson Werth off the plate ended up being called third strikes.

"I wasn't doing it to retaliate, but I tried to come inside, but I couldn't get it in enough," Billingsley said. "I was having a hard time, and that was my fault."

Added Torre, "I think he was mad at himself for being sort of in between in that start." After a relatively calm Game 4 as far as extracurricular activity is concerned following a chippy Game 3, such issues appear to be by the wayside.

But for Billingsley and the Dodgers, no margin of error exists on the playing field with a 3-1 deficit staring them in their face.

"It's pretty much do or die," Billingsley said. "We've just got to come ready to play."
