ST. LOUIS —The St. Louis Cardinals shifted pitcher Adam Wainwright to the 60-day disabled list Thursday because of persistent pain in his right elbow, with no set timetable for his return.

Wainwright has been bothered by the elbow most of the season, and is on the DL for the second time this year.

“Adam is a different sort of equation right now,” said John Mozeliak, the team’s president of baseball operations. “Obviously being placed on the 60, it’s clearly hitting the pause button.”

The Cardinals also put catcher Carson Kelly on the 10-day disabled list with a strained right hamstring, a setback for a team already without the injured Yadier Molina behind the plate. Catcher Steve Baron was called up from Triple-A Memphis.

Wainwright, 36, went on the 10-day disabled list Monday, a day after struggling in a start at San Diego. He walked six in 21/3 innings, giving up two runs and three hits in his first start since April 17.

BRAVES: Rookie Mike Soroka said tightness in the back of his right shoulder isn’t a big concern, even though he was placed on the disabled list for the first time in his four-year pro career.

Soroka, the major leagues’ youngest pitcher at 20, told Manager Brian Snitker on Wednesday that he wasn’t feeling 100 percent heading into his start Thursday against the Chicago Cubs.

Atlanta placed him on the 10-day disabled list with a right shoulder strain only hours before what would have been his fourth career start.

NATIONALS: The team said catcher Matt Wieters had an operation on his left hamstring.

Wieters had the surgery Wednesday.

The Nationals indicated more information would be provided after Wieters is examined by the club’s medical staff.

RANGERS: Texas scratched left-hander Cole Hamels from his start against the Chicago White Sox due to neck stiffness.

Hamels said he woke up Wednesday with a stiff neck and it kept getting worse. He could barely sit on the plane from Seattle to Chicago.
