CHICAGO -- The Cardinals will need to find two spot starters for their upcoming series in Cincinnati now that right-hander Carlos Martinez has been placed on the 10-day disabled list with a right oblique strain.
Martinez described feeling a pull in his right side when he lunged for a ground ball in the final inning of his start on Thursday. He didn't make the play and went on to allow five runs in a 28-pitch fifth inning that turned the game. Martinez assured the Cardinals that he could continue to compete, but the Cardinals opted to go ahead and move him to the DL so that they could add an extra reliever for their doubleheader on Saturday.
Interim manager Mike Shildt said the club is "super optimistic" that Martinez will miss only one start.
Taking Martinez's place on the active roster Saturday was John Brebbia, who gives the Cardinals a long-relief option out of the 'pen. The Cardinals also activated starter Miles Mikolas from the paternity list, optioned reliever Matt Bowman to Triple-A and added Luke Weaver as the 26th man in a series of roster moves before the doubleheader.

Though Mikolas won't pitch until Sunday, the Cardinals were required to reinstate him 72 hours after he went on paternity leave. Mikolas, who had returned to Jupiter, Fla., for the birth of his twins on Monday, was scheduled to arrive in Chicago midday on Saturday.
The Cardinals intend to announce their pitching plans for next week following Saturday's game.
As for Martinez, he will remain with the club through the remainder of the road trip and will be eligible to return from the DL on July 30. The Cardinals did not feel the injury was severe enough to order an MRI for Martinez, though they did give him an anti-inflammatory injection on Friday to promote healing around his oblique.
"It's possible that in a different situation, we would have held off on a DL and seen how he reacted," general manager Mike Girsch said. "We're hoping it's only going to be one [missed] start."
The Cardinals characterized this oblique strain as much milder than the one that has sidelined starting pitcher Michael Wacha since June 20. Wacha has still not been cleared to begin a throwing program and is unlikely to return to the rotation until at least late August.
Martinez already missed four weeks earlier this year while nursing an injury to his right lat muscle. Since returning, he has posted a 5.32 ERA and finished six innings in just three of nine starts. The Cubs tagged him for six runs (five earned) in five innings on Thursday.
"Just rest right now and take care of myself every day," Martinez said. "It's hard for me because I want to compete. I want to help myself and help my team."

Call from the Hall
The National Baseball Hall of Fame reached out to Matt Carpenter to request a donation from his historic performance on Friday afternoon. Carpenter became the first player in Major League history with five extra-base hits in the first six innings of a game, and just the second to hit three homers and two doubles.
As of Saturday morning, Carpenter was still deciding what to send to Cooperstown, N.Y. Of course, if it was hoping to procure some batting gloves, the Hall of Fame will be disappointed. Carpenter hasn't worn any for years.
The Cardinals did set aside Friday's lineup card for Carpenter to take home as a keepsake.
Minor matters
• After going 12-for-24 in eight games with the Gulf Coast League Cardinals, Cardinals second-round Draft selection Luken Baker earned a promotion to Class A Peoria (Ill.). Girsch said the Cardinals planned for Baker's GCL stint to be short, as they were treating it as a rehab assignment of sorts given that Baker was returning from a left leg and ankle injury suffered this spring at Texas Christian University.
• Injured prospect Ryan Helsley is progressing through a throwing program, Girsch said, and is expected back in a Minor League rotation soon. Helsley has been sidelined by shoulder fatigue since June 9.
