Morgan (knee) began a rehab assignment at the rookie-level Arizona Complex League on Wednesday, yielding one hit and two walks with one strikeout in one-third of an inning, Jeff Sanders of The San Diego Union-Tribune reports.
It's the first game action since late June for Morgan, who is coming back from left knee inflammation. If all goes well, the reliever could make a few more rehab appearances before rejoining the Padres' bullpen at some point in the latter portion of July.
