Peacock is scheduled to start Game 2 of Saturday's doubleheader against the A's, Jake Kaplan of the Houston Chronicle reports.

Peacock will take one more turn in the rotation as the Astros look to give Dallas Keuchel an extra day of rest before his next start. While the 29-year-old has held his own in a starting role this season, compiling a 3.34 ERA and 115 strikeouts in 89 innings (17 starts), he could ultimately be headed back to the bullpen following Saturday's outing with Lance McCullers (back) nearing a return to the rotation. Even if Peacock is shifted to the bullpen, he'll remain the Astros' top option for a spot start down the stretch.
