Pecko will start for the Astros in Sunday's series finale against the Mets, Chandler Rome of The Athletic reports.
Mike Burrows (elbow) made his third rehab outing this past Wednesday, so Pecko will get one more turn through the rotation until the former is officially cleared to return from the injured list. Pecko has struggled over the first two games of his major-league career, allowing seven runs on eight hits (including two homers) and seven walks while striking out five across eight innings.
