johnson (groin) completed a bullpen session Tuesday, Kevin Acee of The San Diego Union-Tribune reports.

EDGE Analysis

The activity represents another step in the right direction for Johnson, whom the Padres are hoping can make a full recovery from his strained groin in advance of Opening Day. Johnson could be cleared to face hitters in live batting practice or a simulated game by the end of the week, though he appears unlikely to pitch again during the Padres' Cactus League schedule.
