Marquez will serve as the Padres' opening pitcher for Tuesday's game against the Diamondbacks, Jeff Sanders of The San Diego Union-Tribune reports.
Marquez made six starts for the Padres earlier this season and made a three-inning relief appearance in Thursday's 12-7 loss to the Dodgers following his return from the injured list, so he'll be able to provide more length at the beginning of the game than the typical opener. The Padres are expected to recall Jhony Brito from Triple-A El Paso and have him cover multiple innings behind Marquez during Tuesday's contest.
