McCullers (forearm) is scheduled to make a rehab start Friday for Double-A Corpus Christi, Mark Berman of Fox 26 Houston reports.
McCullers is expected to toss two innings Friday in San Antonio in what will mark his first game action since October, when he exited in Game 4 of the Astros' ALDS matchup with the White Sox due to forearm discomfort. Given the length of his absence, the right-hander will need to make multiple starts during his rehab assignment while gradually upping his pitch count. He could be ready to make his return from the 60-day injured list at some point around mid-August.
