After being reassigned to the bullpen in July, Correia is making his second spot start on Tuesday as the Pirates reshuffle their rotation in the midst of a stretch of playing 20 straight games.
Correia began the season 1-5 with a 4.50 ERA, but he has won a career-best seven straight decisions. He is 9-6 with a 4.49 ERA.
What is next for Correia after this start is still uncertain.
"We're evaluating it day to day, start to start," manager Clint Hurdle said. "This won't be a make-or-break for him."
Correia will be opposed by Billingsley, who has looked like a completely different pitcher in the first half compared with the second.
After missing his first scheduled post-All-Star break start, the veteran righty has won four straight starts. He made a brief trip to the disabled list after the break with a sore elbow after losing five straight starts heading into the break.
Billingsley, who has given up just six runs in 26 2/3 innings in his last four starts, couldn't come up with a reason for his turnaround after his last start.
"He's been around the plate and he's been throwing strikes," said manager Don Mattingly, who tried his best to give an answer.
Dodgers: Hairston hits the disabled list
Infielder Jerry Hairston was placed on the 15-day disabled list on Monday with inflammation in his left hip. He was replaced by Elian Herrera, who was called up from Triple-A Albuquerque.
Hairston, who said he has been playing through hip tightness all season, felt discomfort diving for Donovan Solano's bouncer inside third base in Saturday night's 7-3 loss to the Marlins. He exited the game in the seventh inning.
"Obviously, the hip thing was more of an issue than we thought," Mattingly said. "It kind of went from being a day-to-day thing for us to, all of a sudden, looking at 15 [days] -- hopefully 15. He said it's been bothering him like three months."
Hairston has hit .273 with four home runs and 26 RBIs in 78 games this season.
Pirates: Team shuffles rotation
Manager Clint Hurdle and pitching coach Ray Searage reworked the rotation so every starter gets at least an extra fifth day of rest, except for A.J. Burnett, who will now face the Dodgers in Thursday's series finale.
Correia's start on Tuesday gives the other starters an extra day of rest. Burnett voiced a preference to stay on a five-day schedule.
With the rotation changes, Burnett gets an extra start at PNC Park, where he has won seven of eight decisions with an ERA more than two runs lower than on the road (2.33 vs. 4.43).
"We tried to figure out how our staff ace is best served and adjust accordingly," Hurdle said. "
The Pirates entered this week's four-game series having scored four runs in three previous games against the Dodgers, going 19-for-94 in those games. They scored four runs on eight hits in Monday's opener.
Shane Victorino hit his first Dodgers home run Monday night with a two-run blast in the fifth inning. He hit nine home runs with the Phillies before being traded.
