The Padres placed Pomeranz on the 10-day injured list Friday with left forearm inflammation.
The lefty has appeared in four games since returning from a lat injury June 29, allowing three hits and walking two in 3.1 scoreless innings. Per Dennis Lin of The Athletic, manager Jayce Tingler said Friday that Pomeranz could be activated when he's first eligible to come off the IL on July 17, so the injury doesn't appear to be serious as of now.
