Junk is scheduled to start Wednesday's game against the White Sox, Jeff Fletcher of The Orange County Register reports.
Junk will pick up a second start after he made his big-league debut Sept. 5 against the Rangers, covering 3.2 innings while giving up five runs (one earned) on six hits and a walk to take a loss. The Halos could get Alex Cobb (finger) back from the injured list for Thursday's series finale in Chicago, so unless the team expands its rotation back to six men, Junk may not draw any additional starts beyond Wednesday's outing.
