Harrison (back) will make at least one additional rehab start after Saturday's outing for Double-A Frisco, the Dallas Morning News reports.
The original plan was for Harrison to return around April 23, but a rainout prior to his last rehab start threw the lefty off schedule. He struggled to get loose the day after the rainout, and lumbered through just 3.1 innings. Harrison expects to throw six innings Saturday, but it sounds like there's at least a chance the team leaves him in the minors for two additional starts.
