Urias will make a spot start Thursday against the Nationals, Bill Plunkett of the Orange County Register reports.
Urias had been recently pitching out of the bullpen in Triple-A, which could limit his pitch count further than the mid-80s he tossed prior. Wednesday's starter, Hyun-Jin Ryu (elbow), was placed on the 15-day disabled list Tuesday, leading to Bud Norris being bumped up and the youngster's insertion (possibly temporarily) into the rotation for Thursday's start. Given the team's attempt to limit his innings, it's possible Urias' stay with the big league club will be a short one.
