Edward Cabrera (hamstring) allowed three runs over 1 2/3 innings on Friday in a minor league rehab start for Triple-A Iowa.

The results are a secondary concern since Cabrera looked sharp from a raw stuff standpoint, hitting 98.8 mph with his fastball during his first rehab outing. The 28-year-old, who is working his way back from a moderate left hamstring strain, struck out three and threw 43 pitches. Cubs manager Craig Counsell told reports on Friday that he’ll probably need two additional tune-up outings to continue building up his pitch count and stamina. That timeline puts Cabrera back in the Cubs’ rotation sometime around mid-August.
