Young, who is on the disabled list with a strained right shoulder, allowed four walks and allowed two hits while getting two outs. He threw 35 pitches, 15 for strikes.
San Diego manager Bud Black said after Sunday's 8-0 victory over the Brewers that he had yet to receive a report about Young and how he felt after the start.
If Young feels no residual pain from his start, he'll likely get at least one more, possibly with Triple-A Portland, later in the week before any determination is made on when and if he'll return to the Padres' rotation.
Young has been on the disabled list since April 7, a day after he threw six shutout innings in his first and only appearance this season with the Padres.
