Mets RHP Anthony Swarzak has been placed on the disabled list with right shoulder inflammation, the team announced.
Jacob Rhame was promoted from Triple-A Las Vegas to take Swarzak's place.
Manager Mickey Callaway said Swarzak's MRI showed "just a little bit of inflammation" and that he believes the right-hander will only be on the disabled list for a short period of time.
"It's something that kind of happened over time," Swarzak said while noting that he was glad the inflammation was caught early on.
Swarzak had been sharing closer duties as of late and turned in four straight scoreless outings, but his season overall has been marred by struggles on the mound and trips to the disabled list. He was placed on the 10-day disabled list April 1 with a strained left oblique injury and did not return until June.
Swarzak has a 6.00 ERA with 24 strikeouts in 22 games this season for the Mets.
