The Astros said Monday that McHugh will make a rehab start for the Grizzlies in Thursday’s 7:05 p.m. game against the Reno Aces.
McHugh started the regular season on the 10-day disabled list, where he went after suffering a dead right arm during spring training. He was in Houston for Monday’s season-opening festivities as the Astros hosted Seattle.
The five-year major-league veteran was 13-10 with a 4.34 ERA and a career-high 177 strikeouts last season for Houston.
In 2015, he had a career-high 19 wins and was the Astros’ starter in Game 1 of the American League Division Series against Kansas City.
