The Padres placed Adam on the 15-day injured list Thursday, retroactive to Tuesday, with a right shoulder strain.
In a corresponding move, the Padres reinstated German Marquez (forearm) from the 15-day injured list. Adam will be eligible to return after the All-Star break if he's recovered by then. The reliever had a 0.90 ERA heading into June, but he had a 5.11 ERA across his 12.1 innings pitched during that month.
