McCullers (foot) will start either the second or third game of the regular season, Brian McTaggart of the Astros' official site reports.
McCullers, who was forced to leave his last start due to a foot injury, will make his fourth spring start Saturday against the Nationals. The injury was not considered serious at the time, a notion supported by manager A.J. Hinch penciling him in for a start during the first rotation of the regular season. The only thing to be determined is the rotation's order. As expected, Hinch named Dallas Keuchel the Opening Day starter followed by McCullers and Charlie Morton in a yet-to-be-determined order.
