The Twins start right-hander Mike Pelfrey in Game 1 of Thursday's day-night doubleheader, and left-hander Kris Johnson will be recalled from Triple-A Rochester to start Game 2.
The Dodgers start right-hander Dan Haren in the opener, and starter Red Patterson will make his Major League debut in the nightcap at Target Field.
Manager Don Mattingly had said Wednesday it would "probably" be Patterson, an interesting choice as a non-roster invitee to Spring Training who had been pitching for Triple-A Albuquerque and wasn't on the 40-man roster until Thursday.
By calling up Patterson, the Dodgers are skipping past Matt Magill and Stephen Fife, who have been struggling in the Albuquerque rotation.
Pelfrey has struggled this season with a 7.32 ERA in four starts, but was a tad better in his last outing against the Rays on April 23, giving up three runs over five innings. Here's what he said:
"I thought it was better, but it's obviously nowhere close to where I want to be."
Johnson, meanwhile, was pitching well at Rochester, posting a 2.86 ERA with 20 strikeouts and eight walks in 22 innings.
"He was throwing very well," Twins manager Ron Gardenhire said. "He was the recommended guy. He also threw the ball well for us Spring Training. So we'll see how it goes."
And here's Johnson on what was working for him:
"I was able to locate my fastball pretty well and change speeds when I needed to. Just miss the barrel."
And how he got the jitters out of the way, making his first big league start with the Pirates last September.
"It's a different clubhouse and a different group of guys but it's still the same game. I got the jitters out of the way. So hopefully I can just go out there and pitch like I know I can."
Dodgers: Kershaw passes test
• Clayton Kershaw threw 86 pitches in his Wednesday night rehab assignment at Double-A Chattanooga, and one of the most interested teammates was Zack Greinke, who said he checked pregame Twitter feeds to keep track of Kershaw's progress.
"It's fun watching him pitch," Greinke said of Kershaw. "He's as good as it gets. It sounds like he's doing pretty good."
Kershaw figures to return to the Dodgers' rotation next week in Washington.
Twins: Escobar has big night at the plate
• No. 9 hitter Eduardo Escobar set a single-game career high with four hits Wednesday night and joined Jason Kubel as the only Twins with four hits in a game this season.
Escobar's .345 average is the highest on the club.
• Official scorer Don Hartack ruled that a Rockies' run from Sunday's game against Hyun-Jin Ryu was unearned because of Ryu's fielding error.
• The Dodgers are 11-4 in their last 15 Interleague games and are 9-3 on the road this year.
• Minnesota has lost five straight Interleague games dating to last year.
• The Twins are 11-3 in split doubleheaders since 2012.
