Correia is expected to make his debut for the NL-leading Dodgers as they try to halt Julio Teheran's success at home for the Atlanta Braves on Monday night.
Amidst 20 straight days without a day off, Los Angeles (67-52) was scheduled to start Dan Haren in this game, but instead will go with Correia, who was acquired from Minnesota on Saturday.
''As of right now, we'll use (Correia) for a spot start and out of the bullpen,'' Mattingly said. ''Hypothetically speaking, during this stretch of games in a row we can give our guys a bit of a breather.''
An All-Star with Pittsburgh in 2011, Correia was 5-13 with a 4.94 ERA in 23 starts for the Twins this season. However, the right-hander has yielded four earned runs in 12 innings in his last two.
"I'm getting toward the end of my career and you want to play in some meaningful games," said Correia, a Southern California native who has pitched for San Diego and San Francisco.
He is 3-3 with a 4.24 ERA in eight starts versus Atlanta (60-57).
Teammate Adrian Gonzalez is 9 for 14 with three doubles, two home runs and seven RBIs in the last four contests. He had two doubles and two RBIs as the Dodgers salvaged the finale of their three-game set at Milwaukee with a 5-1 victory on Sunday.
''Hopefully it gets us going in the right direction again,'' Mattingly said.
