Padres manager Bud Black said Young will be held to three innings of work or between 50 and 55 pitches on Tuesday night, when he toes the rubber for Triple-A Portland.
"This is not unlike a Spring Training situation," Black explained before San Diego opened a three-game set in Arizona. "He's got to build up pitch count, got to build up just the consistency of his pitches in game-like conditions.
"If Chris does come back, we don't expect a nine-inning complete game."
Young, on the 60-day disabled list since April with a strained right shoulder, threw 55 pitches in an issue-free simulated game on Thursday at PETCO Park. He pitched for Double-A San Antonio in May but had a setback.
