Sunday's game against the Rockies might help clear up half of that issue. If Vicente Padilla has a strong outing against the Rockies, he could secure a spot in the rotation.
If he falters, then that could insert Jon Garland back into the mix.
And Chad Billingsley will travel to the Dodgers' training complex in Arizona on Monday to pitch a simulated start in what also could be considered an audition for a spot in the postseason rotation.
"We still have a decision to make," Torre said. "We're going to meet here the next couple of days and try to figure out matchups -- if anything makes sense or stands out."
Padilla is the only pitcher out of the trio who hasn't faced the Cardinals this season.
Garland didn't fare particularly well in his two starts against St. Louis this year when he was with the D-backs. He lost both games and gave up seven runs in just 3 2/3 innings during an April start.
He did recover to give up only two runs in six innings against the Cardinals on July 16 but still took a loss.
Billingsley is 1-1 vs. the Cardinals this year. And his last win of the season came against St. Louis on Aug. 18, when he allowed two runs in six innings.
Torre said Billingsley would pitch around five to seven simulated innings in Arizona.
In other news, Ronnie Belliard, who hit the go-ahead RBI single in Saturday's NL West-clinching win over the Rockies, did not start Sunday.
It was thought that the Dodgers would try to give Belliard a start in the final game of the season so that he could get some tuneup at-bats. Belliard sat out five games after straining his left groin Sunday in Pittsburgh.
Belliard should get one pinch-hit at-bat Sunday.
"I wanted to get at-bats, but they talked to me and I understand the situation," Belliard said. "If I played today and got hurt, that would be real bad. I'll get one at-bat and then I should be 90 or 95 percent by Wednesday. So, I understand."
